The physiotherapy management of older adults is not a new concept however, as healthcare advances, the average age of the population increases and it is suggested that the prevalence of frailty will multiply. Subsequently, this causes further demand on the NHS; an already overstretched service. In response to this, there has been an increased drive to improve the efficiency of the management of frailty. There has been a shift of care from reactive to preventative strategies and a focus on providing early interventions to reduce costly unplanned admissions to hospital.
Frailty is defined as:
|“a biological syndrome of decreased reserve and resistance to stressors, resulting from cumulative declines across multiple physiological systems and causing vulnerability to adverse outcomes".|
The British Geriatrics Society (BGS) support that frailty is an age-related health state affecting multiple body systems. They describe Fried's phenotype model which concisely highlights the signs and symptoms of frailty. If an individual satisfies three out of the five criteria, they are diagnosed as being frail (Table 1). However, if one or two criteria are met, they may be deemed as being pre-frail. This can act as an early warning sign for frailty.
|Weight loss||A drop in bodyweight of ≥10lbs/4.5kg in the past year or a drop in bodyweight of ≥5% in the past year.|
|Weakness||Measured using grip strength. A result within the lowest 20 percentiles according to gender and BMI indicates a weakness.|
|Reduced energy/endurance||Self-reported, can also be a predictor of cardiovascular disease.|
|Slowness||The lowest 20 percentile of the population according to gender and standing height, 15ft walking time.|
|Low physical activity||Based on reported activity levels translated into a kilocalories score. Again with a cut-off at the lowest 20th percentile for each gender.|
The phenotype model can also be used as a quick screening assessment tool for frailty. However, the Comprehensive Geriatric Assessment (CGA) is often preferred due to the multi-dimensional and holistic nature. Furthermore, in an international systematic review, it was concluded that prevalence of frailty increased when a psychosocial model of assessment was used as opposed to the biomedical phenotype. Therefore, it would appear the CGA is a more robust measure of assessment and as a result we have decided to use it to illustrate physiotherapy assessment. This will be described in further detail in the assessment section.
The physiotherapist should be aware of the risk factors for frailty. If frailty is suspected, referral to other professionals may be required.
Frailty is associated with poorer outcomes including disabilty and even death. Frailty and disability do not always co-exist, however they can be linked. In some cases, frailty may be a consequence of disability and in others, the causation of disability.
It is important to note that although frailty is age-related, it is not an inevitability. In those aged 65 to 85, there is thought to be a 10% incidence of frailty. However, this figure increases to 25 to 50% in those aged 85 and over.
The success of modern medicine has resulted in an increase in average life expectancy. When the NHS was founded in 1948, 48% of the population died before reaching the age of 65; that figure has now decreased significantly to 14%. People are living longer, and as result, healthcare services are required to transform to better meet the population’s needs.
|Estimated and projected age structure of the UK population 2012-2037|
As seen from the above graph, the percentage of the population aged over 65 is set to dramatically increase. As a result, it is thought that there could also be rise in the number of frail older adults in Scotland. Older adults and indeed frail adults are more likely to require healthcare resulting in a surge of pressure on the NHS; an already strained service.
If you would like to view an animated version of the projected population growth, watch the video below.
|UK population pyramid|
70% of day beds are occupied by people over 65; this is more than 51,000 beds at any one time. 85 year olds on average stay in hospital eight days longer than their younger counterparts.
Most emergency admissions to hospital happen through accident and emergency departments. On average, a person over 85 spends 11 days in hospital. If they pass through accident and emergency the total spent is approximately £3241 per patient, per visit (Table 2). However, more than a 25% of over 85 year olds stay for 2 weeks and 10% stay longer than a month, when admitted as an emergency . This means that even more money is spent.
410,377 elderly persons were admitted to hospital due to a fall in 2013. Appropriate strategies could prevent this by up to 30%.
The length of time frail people stay in hospital differs throughout the world. The UK is 16th shortest in the world when it comes to average length of stay in hospital. However, admittance to hospital and the cost implications of long term hospital stays are similar worldwide to the UK.
Based upon the statistics and projections from the Scottish Government, over the next decade we will be faced with an ageing population with more elderly dependants. This means that there will be more of a financial strain on the NHS due to the prolonged hospital stays associated with age. This indicates a need for change avoiding costly hospital admissions unless absolutely necessary. There are three ways the NHS can help reduce costs
- Health and social care integration
- Preventative medicine
- Increased provision in the community.
Health and social care integration aims to increase the effectiveness of care while keeping associated costs low. The Department of Health report that at least one third of emergency admissions could be dealt with in the community Providing a free movement of information between hospitals and the community will allow increased communication and will reduce hospital admissions .
Preventative healthcare strategies include
- Promoting healthy behaviours like physical activity
- Reducing tobacco and alcohol use
- Improving community facilities to promote physical activities.
- Raising awareness of frailty
Older People's Acute Care Improvement Programme (OPAC)
As the number of older people is increasing, there is an increased need to ensure appropriate care for them. Improving older people's acute care is a priority for the Scottish Government and in 2012 “The Older People’s Acute Care improvement programme (OPAC)” was commissioned by the Scottish Government.
The programme focuses on 2 key areas:
In relation to frailty, the programme focused on identification and immediate management of frailty. This included screening for frailty and ensuring that older people who were identified as frail received a CGA within 24 hours of admission. 
Healthcare Improvement Scotland reported the impact of the programme and found that:
- Frailty screening in 3 surgical wards at the Royal Infirmary of Edinburgh decreased the length of stay, number of falls and number of complaints
- A reduced length of stay in NHS Grampian
- 50% decrease in the number of falls per month in 2 wards in NHS Greater Glasgow and Clyde
The report emphasises the importance to continue building on this work and Healthcare Improvement Scotland is committed to continue working with NHS Boards and staff to support learning and improvement of skills in relation to the management of frailty and delirium .
Think Frailty was an initiative funded by the Scottish Government and was part of the Healthcare Improvement, Scotland's policy to improve health care for older people due to the rising numbers of unplanned admissions of this population. There is strong evidence for the benefits of CGA for frail patients. The programme is aiming to ensure that 95% of frail patients have a CGA and are admitted or referred to a specialist unit within 24 hours of admission. This case study report focuses on the work to identify frailty and ensure rapid CGA in four NHS boards in Scotland: NHS Ayrshire & Arran, NHS Grampian, NHS Lanarkshire and NHS Lothian. Common themes underpinning the success in the NHS boards mentioned in the report included:
Easy to use screening tool
The use of these should be at first point of contact with older people; at the front door or at home
- Important to enable rapid identification and referral to CGA
- Valid screening tools reduce variability and increases the number of appropriate referrals to frailty services.
Early intervention & Senior decision makers
- Senior decision makers were valued, particularly in NHS Ayrshire & Arran and NHS Grampian. As senior clinicians were more likely to use a wider range of care management options other than admission
- Early intervention focusing on discharge planning
Multidisciplinary team working
- Having a strong, integrated team was valued by all sites
- Good communication between the members of the MDT was important
- Common aim for all sites: expanding the team. In particular physiotherapy and OT services so that a 7 day a week, around the clock service is available.
The sites involved in this project were able to show significant improvements in outcomes for the frail elderly presenting at the hospital.
These outcomes included a reduction in the number of admissions and re-admissions to hospital.

Fit for Frailty
Part 1: Recognition and management of frailty in individuals in community and outpatient settings
This part of the Fit for Frailty guidelines by the British Geriatric Society (BGS) are intended to support health and social care professionals working with frail older people in the community.
In order to recognise and identify frailty, BGS recommends:
- During all encounters with health and social care professionals older people should be assessed for frailty
- There are 5 main syndromes of frailty; Falls, change in mobility, delirium, change in continence and susceptibility to side effects of medication. Encountering one of these should raise suspicion of frailty.
- Gait speed, timed up and go test and the PRISMA questionnaire are recommended outcome measures to assess for frailty.
For managing frailty in an individual, BGS recommends:
- A CGA, which involves a holistic, multidimensional and multidisciplinary assessment of an individual
- The result of the CGA should be an individualised care and support plan (CSP).
- The CSP includes a named health or social care professional coordinating the person’s care. A plan for maintaining and optimising the person’s care as well as urgent, escalation and end of life care plans should be in place.
Gap in Literature
Clinical guidelines provide evidence-based recommendations in relation to the management of a specific condition or syndrome. They are aiming to assist health and social care professionals in their decision making and help reduce undesirable variations in practice.
The guidelines on frailty discussed above are aimed to all health and social care professionals and it has been found that these rarely go in depth in their explanation of specific healthcare professional's roles. As physiotherapists, it can be difficult to identify what recommendations are most applicable to our practice in relation to the management of frailty.
In the Fit for Frailty guidelines, it is suggested that physiotherapists should play a role in assessing and treating frailty. It is reported that during every encounter with healthcare professionals, older people should be assessed for frailty. In addition to this, they also suggest that frail older adults would benefit from multidisciplinary assessment and intervention.
In the Think Frailty document, NHS Grampian reports physiotherapists are involved in the rapid MDT assessment team, seeing those who meet the frailty criteria. NHS Lanarkshire states that physiotherapists work in an early discharge team to see frail patients at the front door. Whilst NHS Lothian’s frailty screening tool suggests a referral to physiotherapy if the patient meets the appropriate criteria.
Introduction to the Physiotherapists' Role
The nature of the physiotherapy profession is to help restore movement and function in someone affected by illness or injury. Physiotherapy input in the treatment for frailty is not a new concept. However, as previously discussed, the delivery of care is evolving in order to better meet the needs of this population. Physiotherapist’s are expanding their service to deliver intervention outwith standard inpatient care and moving to several different settings; for example, within day hospitals, in the patient’s home and in community clinics.
There is an emerging body of evidence supporting physiotherapy in emergency departments to assess and treat trauma and soft tissue injuries. However, could physiotherapists be included in emergency services to assist in preventing admissions of frail patients?
In 2015, a physiotherapist joined forces with paramedics to treat non-life threatening emergency calls, with the aim of preventing unnecessary A&E attendances and reducing hospital admissions. Commonly seen conditions included falls, chronic pain, decreased mobility, exacerbations of long-term conditions and frailty. 57% of patients remained at home and it is thought that £2850 was saved every time a patient was not transferred to hospital.
Furthermore, it has been suggested that physiotherapists could be stationed within hospital A&E departments to undertake frailty and falls risk screening and make rapid decisions on whether the patient can safely return to their pre-admission destination. However, little high quality research has been conducted and at present evidence is inconclusive, suggesting the need for further study in this area.
The Comprehensive Geriatric Assessment (CGA)
Many of the guidelines available state a need for a CGA to be completed to diagnose patients who may be frail. From this assessment, a holistic interdisciplinary treatment program can be devised to suit the problems and needs of the individual. The assessment is usually carried out by a geriatrician or another trained professional, such as a physiotherapist.
This assessment usually takes place when a patient is identified as possibly being frail; during acute illness, prior to surgery or when returning to a community environment. It is a multi-dimensional program, which looks at the patient's health (physical and mental), mobility and social status. This approach was introduced in 2001 by the Department of Health. There are five domains in which assessment takes place. Below is a table adapted from Martin, which identifies and outlines what should be included in each domain.
The assessment will allow health professionals to identify the problems and allow for onward referral now and in the future. Once specific problems have been identified, onward referral can be made to appropriate healthcare professionals. This can then allow for a thorough assessment to be made around these problems. For example, a patient may be referred to physiotherapy to help increase mobility.
A study examined whether a comprehensive assessment after an emergency admission is more effective when carried out by a team trained in a using a CGA. The paper showed that this approach reduced costs, length of hospital stay, deterioration and mortality. Routine follow up appointments are an essential part of the CGA and identify effectiveness of treatment. There is no specific time frame for these, yet follow up sessions usually occur when people are readmitted to hospital.
In hospitalised patients, it has been shown to improve the accuracy of diagnosis and enhances management in both the long and short term. Completing a CGA in the community can prevent reductions in mobility and problems which arise from poor mobility by implementing treatment programmes tailored to all the patients’ needs. It can also reduce hospital stay, decrease the likelihood of readmission to hospital and reduce mortality.
Below we have split the physiotherapy assessment into the CGA sections to show that physiotherapists can use its structure to help them carry out a comprehensive, holistic assessment.
There is a lack of evidence supporting the use of specific assessment techniques for physiotherapists to adopt to complete a comprehensive functional assessment of a frail elderly person. However, there is a lot of evidence supporting the use of specific outcome measures within this population. These will be covered later in this section.
Due to the above gap, only assessment techniques which have been reported in the literature will be included in this learning resource. There may be some common areas of assessment not covered; this does not mean they are not valid or useful to review when working with frail patients.
What is a Functional Assessment?
Functional assessments are a way of determining health needs now and in the future. Assessments of patients with frailty should occur after every illness or injury to establish the effect the episode had on the patient’s functional ability. More specifically, functional assessments should be done on every patient over 75 years old. The functional assessment element of the CGA compromises of: gait, balance, abilities to carry out activities of daily living (both fundamental and basic) and activity/exercise status. All these areas should be assessed by the attending physiotherapist.
The subjective assessment will be very similar to that of any other patient. Yet, some specific questions related to age and frailty must be asked.
- Has anything changed recently in terms of the patient's: vision, hearing, mobility status, cognitive ability, medication usage or activity levels?
- Falls risk assessment tool (FRAT) questions should be asked which regard falls history and mobility status. When did they last fall and why? How often do they fall? The context around circumstances of the fall should also be asked, like mechanism of fall, home set up and medication use.
- It is useful to know about the patient's dietary intake.
- Do they have help or support with activities of daily living from anyone? Do they give help or support to anyone?.
It is important to know any changes which could affect the rest of your assessment and treatment plan. How could these changes have impacted on the patient's life? Can we help to change any issue or problem? We need to know about any previous falls. This will help determine their mobility status and how well they are coping. The FRAT tool is helpful to determine future falls risk.We can then tailor treatment where it is needed. You can get an idea of what ADL’s they are able to do, how they are coping with these demands and how busy they are throughout the day.
The objective assessment should begin by observing posture, skin condition and body shape. This can give you clues as to their general health and the extent of their frailty.
The therapist should have an idea as to what level of independence the patient has and how much physical activity they carry out on a daily basis. This can be achieved by using outcome measures such as the timed up and go, which has been shown to have good reliability and validity as a tool for measuring the mobility status of patients who are frail . This type of information can also be gathered through the subjective assessment.
Gait. Keeping track of the patient’s gait speed will enable the physiotherapist to objectively measure patient progress. Endurance can be tested by completing multiple sit to stands or by carrying out a Six-Minute Walk Test. Monitoring the patient's heart rate during this will give an indication of their bodies ability to respond to increased effort. The six minute walk test has been shown to be valid and reliable within this population. Measuring endurance gives the physiotherapist an indication of how far the patient is likely to be able to walk, which can aid treatment planning and goal setting.
Analysing the individuals gait is also important. However, the difference in gait in people who are frail has not been widely researched. As well as frail individuals having reduced gait speed, they also have reduced stride length and cadence. Reductions in stride length are linked with the severity of frailty and come about due to sarcopenia and associated lower limb weakness. It is advised that in order to truly assess gait, the person should be asked to walk at their maximum speed.
Balance should be assessed comprehensively as this will allow for individualised treatment. 75% of people over 70 have reduced balance, which can increase falls risk. Whilst some physiotherapists prefer using their own observations to assess balance, others favour the use of standardised outcome measures. The Berg Balance Scale, Single Leg Stance Test and Timed Up and Go were seen by physiotherapists as useful tools to measure functional ability. Furthermore, balance outcome measures were assessed in a systematic review for their psychometric properties. There are many which the physiotherapist can use, however, very few measure all aspects of balance. Testing a patient's reactive balance was one area which was rarely examined. It is therefore important to know what aspects of balance and postural awareness are being tested by the outcome measure so that treatment will be tailored to problems. Reduced balance is linked with increasing falls risk and hospitalisation. Good indicators of falls risk are the Berg Balance Scale and the Tinneti Balance and Gait Assessment as these both look at functional balance. A home assessment can identify if modifications need to occur to allow for increased safety. See the Environment section.
Range of Motion (ROM) and Strength
As previously mentioned, reduced grip strength is an indicator of frailty. Grip strength can be tested by using a grip ball dynamometer and which has been shown to be accurate and comfortable for people with frailty to use. It is important to measure grip strength, as weakness can limit the patient's ability to carry out activities of daily living. Determining ROM is important with this population as a link between reduced lower limb mobility and fall prevalence has been found. Ankle plantarflexion and hip extension, internal rotation and abduction were found to be reduced. Tibiotarsal range is also important to measure as it can impact on posture. It is therefore important to establish if your patient has reduced ROM as tailored intervention may help reduce falls.
Activities of Daily Living (ADLs)
- Basic ADLs are self-care tasks, whereas,
- instrumental ADLs are activities which are needed for a person to live independently in the community.
ADLs are important to measure as an inability to do these is a better indicator of dysfunction than ability to self-care. The percentage of elderly people reported as being independent increased to 65.4% from 46.5% when looking at basic ADLs, when compared to IADLs. There are standardised outcome measures in which to assess IADLs, yet the specific activities needed to enable independence vary depending on the environment and social aspects of the patient's life. It is therefore important to have a grasp of what the patient needs to be able to do to remain independent and then review these activities. Functional dependence should be assessed, as there are correlations between dependence and increased length of stay in hospital.
Outcome measures may be useful to assess the patient's ability, but also to track the patient’s progress. There are many different outcome measures to choose from in this population. Some were specifically designed for frailty, while others were developed for other conditions but have been shown to have good psychometric properties within this population. The next section will review some commonly used outcome measures. However, this is not an exhortative list and will not necessarily be the best to use with each patient. It is up to the clinician to select the most appropriate measure for their practice.
| Outcome Measures (OM)
|| Description of OM
|| Psychometric properties|
| Frail elderly functional assessment
| 10 Metre Walk Test
|| 10 Metre Walk Test
| The Edmonton Frail Scale
|| 12 questions related to cognition, general health status, mobility, social status, medication use, nutrition, mood, continence and functional performance. It has a total score of 17 which depicts severe frailty. It is a very brief way of assessing for frailty and can be used to see whether a CGA should take place.
| PRISMA 7
|| A questionnaire devised of seven yes or no questions that can be used when the patient is unable to carry out a Stand Up and Go or a 10 Metre Walk Test. It was developed with a service in Canadian healthcare, to integrate frailty assessment and management and allow for increase patient-centred care.
| The Barthel Index
|| It measures the patient's ability to look after themselves by asking 10 questions and answers that are graded on the amount of assistance needed to carry out the activity.
| Tinetti Balance and Gait Assessment
|| The Tinetti is a 17 item OM used to assess gait and balance.
| Elderly Mobility Scale
|| Assesses mobility in the frail by completing 20 components.
Both the Edmonton frail scale and the PRISMA 7 can be used by physiotherapists to determine whether a patient who displays symptoms of frailty is frail or not. If a positive result is found, they could refer a patient back to their GP for further assessment and intervention.
The Effects of Ageing
As the human body ages, it is susceptible to various changes.
- Blood vessels and arteries stiffen
- Increase stress on the heart to maintain oxygen levels in the body.
- Increase risk of cardiovascular disease
- Reduced levels of minerals, bones become less dense and more fragile.
- Susceptible to osteoporosis and fractures.
- Reduced growth hormone
- Also affecting respiratory muscles and gastrointestinal tract
- 10% loss of brain volume after aged 80
- Reduction in blood flow and levels of chemical neurotransmitters
- Reduced attention and memory.
Frail adults are highly likely to be prescribed medication to treat their symptoms and co-morbidities. Below you will find a list of common medications, the conditions they are used to treat, some common side effects and some named examples.
Table 5 - Analgesia
|Medication||Conditions used to treat||Common side effects||Examples|
| Non- opioid analgesics
(Non-steroidal anti- inflammatory drugs, NSAIDs)
|Mild to moderate pain||Minimal side effects, however dizziness and headache may occur||paracetamol, aspirin, ibuprofen|
|Compound Analgesics||Mild to moderate pain, often as an addition to NSAIDs||Nausea, loss of concentration, constipation, confusion||co-codamol, co-codaprin, co-dydramol|
|Opioid analgesics||Moderate to severe pain.||Impaired balance, confusion nausea and vomiting, constipation, drowsiness and dizziness||codeine, tramadol morphine|
Table 6 - Other Medication
|Medication||Conditions used to treat||Common side effects||Examples|
|Beta Blockers||Angina, Heart failure, Atrial fibrillation and Heart attach||Dizziness, tiredness, blurred vision, slow heartbeat, impaired balance||atenolol, bisoprolol, acebutolol, metoprolol|
|Antidepressants||Depression|| Dizziness, impaired balance, slow reaction, headaches, loss of appetite, anxious, feeling agitated, blurry vision
|| duloxetine, venlafaxine, mirtazapine, amitriptyline, imipramine, lithium.|
|Benzodiazepines||Relief of severe anxiety||Drowsiness, difficulty concentrating, headaches and vertigo||diazepam, lorazepam, chlordiazepoxide|
|Angiotensin receptor blockers||Hypertension||Dizziness, confusion, muscle cramps and/or weakness, faintness||azilsartan, candesertan, eprosartan, losartan|
Water retention, high blood pressure and heart failure
Nausea, dizziness, muscle cramps, increased frequency and urgency of urination
furosemide, torsemide, chlorthalidone, amiloride
|Anticoagulants||Hypotension||Haemorrhage, dizziness, headaches.||heparin, warfarin and aspirin,|
Side effects of medication such as drowsiness, blurred vision and insomnia can interfere with the treatment session and also delay any recovery. It is therefore important for physiotherapists to know if the patient is on any medication and the associated side effects so they can modify treatments.
Polypharmacy is the use of multiple medications and is often unavoidable as the elderly population are more likely to have several co-morbidities. Polypharmacy introduces drug interaction, this can be harmful as when combined, some medications increase the risk of adverse drug reactions (ADRs).
ADRs can become a vicious cycle where more drugs are prescribed in order to treat side effects. This can result in increased numbers of unnecessary and potentially harmful medications. The physiotherapist can help prevent polypharmacy and the vicious cycle by recognising changes in the patient's response to their drug therapy and highlighting need for medication review. It is fundamental for physiotherapists to have knowledge and understanding of common medicine and their adverse side effects.
Nutrition is important for this population and it should be part of the physiotherapist's subjective assessment to check dietary intake. A physiotherapist can then reinforce good eating habits and if needed, refer the patient to a dietician. It is also important to have an idea about how much the patient eats as this could contribute to increased fatigue. A reduced tolerance to activity is present in frail patients and the physiotherapist should be mindful of this when assessing and treating.
Although it is not the prime role of a physiotherapist, in order to provide a holistic service, we must be aware of and understand the mental health of our patients and the impact that this may have on the individual. Mental health disorders can be classified as organic or functional
Age-related cognitive decline is inevitable, however, some conditions common amongst frail adults can have dramatic effects on cognition. Organic disorders are usually caused by disease affecting the brain, for example, dementia or delirium. Table 7 compares age-related cognitive decline with the early signs of dementia.
|Early signs of dementia||Normal ageing|
|Forgetting things more often than previously, forgetting names of people close to them||Briefly forgetting parts of an experience, forgetting the names of people they rarely see|
|Repeating phrases or conversations||Putting things away incorrectly|
|Unpredictable mood swings||Mood changes appropriately|
|Lack of interest in activities, difficulty making decisions||Changes in their interests|
The word dementia describes a set of symptoms that could include memory disorders, personality changes and impaired reasoning. There are various types of dementia, the most common are Alzheimer’s disease, vascular dementia and dementia with Lewy bodies. The likelihood of developing dementia increases drastically with age and it is thought that 1 in 14 people over 65 suffer from this condition. Due to the progressive nature of the disease, communication will gradually worsen over time.
Delirium is a common clinical syndrome categorised by fluctuating cognitive function and disturbed consciousness. It usually develops over 1–2 days, however, it is associated with poor outcomes. Delirium can be hypoactive or hyperactive, occasionally people will display signs of a mixed picture. Hyperactive delirium usually manifests itself as restlessness, agitation and aggression, whereas people with hypoactive delirium present as withdrawn and quiet. It is thought that the prevalence of delirium on medical wards is 20 to 30%, but reporting in the UK is poor and it is expected this figure is underestimated. People who develop delirium are more likely to stay longer in hospital and have more hospital-acquired complications, such as falls. The physiotherapist may be the patient’s first contact with healthcare and they may be required to screen for delirium. OPAC have created a delirium toolkit (see additional reading) and recommend the use of the 4AT. Any abnormal results should be discussed with the relevant healthcare professionals.
Implications for Physiotherapists?
With any cognitive condition, effective communication may become challenging and prove to be a barrier to successful assessment and treatment. Table 8 highlights some tips to tackle this.
| 1. Keep commands clear and concise with one request at a time – “Stand up please”|
2. Allow plenty of time for a response before repeating your question. If the patient is still struggling, try rephrasing.
3. Remove distractions – this could include talking, background noise, eye-catching pictures.
4. Use names and explanations where possible – “Your daughter, Ann”
5. Use other forms of communication:
Now watch this video which describes effective communication specifically for people with dementia, however, some of this could be applied to anyone with cognitive decline.
|Effective communication and dementia|
Functional disorders have a predominately psychological cause and may include conditions such as depression or anxiety.
1 in 5 community-dwelling older adults are thought to suffer from depression. Whilst this statistic is alarming, it has been suggested that older adults are more susceptible to depression as with age, they become more exposed to chronic conditions, health concerns and death, particularly of loved ones. Depression comes with a whole range of symptoms and these vary from person to person. The following video explores the cause of depression in ageing.
|Depression in ageing|
The most recently published statistics suggest that 17% of older adults suffer from an anxiety disorder. Anxiety has a wide range of physical and psychological symptoms that can have a debilitating effect on an individual’s life; they may be able to complete tasks physically, however, are limited by their mental health. Anxiety disorders are usually treated with medication but alternative therapies such as cognitive behavioural therapy and hypnotherapy are also known to be used.
Implications for Physiotherapists?
Lack of motivation is common amongst most frail adults, including those with a functional mental health disorder and treatment to tackle this can feature heavily in the physiotherapy treatment plan.
Social and Environmental Factors
Assessing this type of information is also a key component of the common assessment framework for adults, which was published by the Department of Health. It is primarily an occupational therapists (OT’s) role to devise interventions and amend any problems with these. Their assessment and the subsequent home modifications and adaptions can help increase the functional abilities of people who are frail. However, a patient's ability to carry out activities in the home is dependent on its layout and their social situation. As physiotherapy interventions try to help improve people's ability to perform ADLs, it is important for physiotherapists to know how the environment and social situation can impact on their treatment. The international classification of health, functioning and disability (ICF) can be used by physiotherapists to help establish the needs of the patient:
The ICF is a model which allows professionals to see the impact a health condition has on a person's life by taking a holistic viewpoint. Participation restrictions and activity limitations are the two areas of the ICF which relate to the influence of the patient's social and environmental circumstances. Activity limitations are the execution of a task by the patient, whereas, participation restrictions relate to how involved with a life situation the patient is due to the societal setup. The World Health Organization (WHO) has devised a checklist which allows clinicians to identify what activity and participation restrictions the patient has.
Frail people who have a high participation level in leisure activities also have better health outcomes. Reduced mobility and activity limitations directly reduce participation in leisure activities. Activity limitations can have a bigger impact on social involvement than the severity of the patient's medical condition. Specific activity limitations which may cause participation restriction are:
- Needing help with personal care
- Mobility aid use and walking speed
Musculoskeletal impairments cause the majority of activity limitations in elderly community-dwelling adults . Physiotherapists are therefore in a prime position to help reduce activity limitations. A study by Mast and Azar found a correlation between ADL limitations and readmission to hospital in the geriatric population. This shows that physiotherapy targeted at reducing activity limitations could reduce hospital stay as well as improving social network and participation.
Taking a Social history
Taking a social history allows the physiotherapist to understand the patient's current level of functioning and their desired functional goals. This should include assessment of activities they do in and outside their home and what formal or informal care or support they receive. 80% of nonagenarians have carers to help with some of their ADLs. Having a small amount of regular help with ADL’s may prevent an acute episode turning into an emergency, where the patient is no longer safe to stay at home. This shows the importance of knowing the patient's social circumstances.
Elderly people who experience activity limitations sometimes also have participation restrictions. Knowing what participation restrictions a patient has is important as they are linked to the patient's quality of life. Participation frequency should also be noted. It is common for people with frailty who live in the community to report having participation restrictions. This is due to reduced community mobility and a reduced ability to carry out work both at home and in the community. Increased participation restrictions are also linked with increasing age. The symptoms of frailty most closely linked to participation restrictions are grip strength, mobility and the number of co-morbidities a patient has. Participation is also linked to environmental factors such as, access to public transport. It has been shown that mobility levels can remain constant even though the patient's condition may decline. The mind map below shows the different things which should be checked in the patients' house on assessment, before a treatment plan is devised or goals are set. Sometimes these assessments are performed jointly with an OT.
It is important to know if any intervention is being put in place to help rectify these. Finding out if an OT is involved, what their findings were and what their plan is, is important as then interdisciplinary goals can be devised, which are safe and suited to the patient Being aware of the environment in which the patient lives will allow the physiotherapist to tailor treatments effectively and safely to their surroundings.
There are several clinical guidelines available for healthcare professionals to assist them in preventing hospital admissions providing quality care for patients. However, whilst they recommend physiotherapy intervention, these guidelines lack rigorous information and evidence surrounding treatment. As two thirds of NHS clients are aged 65 or over, there is a plethora of different occasions in which an older person may be admitted to hospital, however, it can be loosely split into two categories: injury and illness .
Injuries leading to hospitalisation are more common in people over 65 and they can be more critical and more often preventable. The increasing age of the population heightens the significance of this problem. Falls represent the most frequent and serious type of accident in people aged 65 and over in the UK . Gowing and Jain found that a fall is the most common mechanism of injury in elderly trauma patients presenting to accident and emergency units and falls cases are the most common presentation to the Scottish Ambulance Service in the older adult population.
A fall is an incident which results in a person coming to rest unintentionally on the floor or ground or other lower level and can result in fracture, dislocation, traumatic brain injury and even death. Anyone can have a fall, however, the natural ageing process means that older people are at higher risk. Over 400 risk factors leading to falls have been highlighted (Table 9).
The risk of falls and related complications increase gradually with age and can be an indication of increasing frailty. Falls represent the main cause of disability and are the leading cause of morbidity and mortality among people over 75 in the UK. Not all falls will result in injury, however in some cases, a fall could be fatal and it is thought that the repercussions of even a minor fall could have catastrophic effects on physical and mental health. Despite the above statistics, falls are not an inevitable consequence of old age. A multifaceted interaction of several risk factors relating to the ageing process, lifestyle choices, environmental factors and the presence of long term conditions determines an individual’s risk of falling. As risk increases with age, it is important for the physiotherapist to identify those at risk early, recognise and modify risk factors and provide timely intervention to prevent falls and subsequent injury. Below are examples of treatment options follows, although this list is not exhaustive.
A significant component of age-related weakness and frailty is sarcopenia. Sarcopenia is the gradual loss of muscle tissue, resulting in diminished strength and it is thought that 2% of skeletal muscle mass is lost each year past the age of 50. Sarcopenia increases the risk of frailty and falls and in turn, hospitalization in the older adult population. Resistance training has been suggested as a potential treatment for sarcopenia and its prevention. Resistance training is designed to improve muscular fitness by exercising a muscle or a muscle group against resistance. This could lead to improved function, increased quality of life and reduced likelihood for falls. Resistance training programmes have consistently shown to improve muscle strength and mass in older adults, however, it is questionable whether this transfers to reducing the risk of falling.
Latham and colleagues have conducted the only trial which has studied the effect of seated resistance training on risk of falls in an older adult population. This study solely involved home-based, progressive, seated quadriceps strength exercises using 60 to 80% of the individuals 1RM with ankle weights. It was found to have no effect on falls rate or risk of falling and an increased chance of musculoskeletal injury. As a result, seated resistance training or high intensity resistance are not recommended. Furthermore, Liu-Ambrose and colleagues examined the effect of a twice weekly course of 50-minute resistance training sessions on number of falls and risk of falls in a female population aged 75-85. Exercises included targeted upper limb, trunk and lower limb muscles and again, resistance training alone was found to have no significant effect on number of falls or risk of falls. However, when combined with agility training, participants did develop a decreased risk of falling. It has been proposed that strength training alone is not enough to fully manage falls risk, however, it should be part of a multi-component falls prevention exercise programme. We will discuss this in further detail later on in the learning resource.
Balance Re-educationBalance disorders are very common in frail older adults and are a key cause of falls in this population. They are associated with reduced level of function, as well as an increased risk of disease and death. Most balance disorders comprise of several contributing factors including long-term conditions and medication side effects. Recent research conducted examined the effectiveness of two-year progressive balance retraining in reducing injurious falls among community-dwelling women aged 75-85. The study took place over 20 centres and recruited 706 participants, who were randomised in to the intervention group, who received weekly dynamic balance exercise supplemented by prescribed home exercise, or the control group, who did not take part in the exercise. Over the two-year intervention period, the injurious fall rate was 19% lower in the intervention group than in the control group highlighting the benefit of a balance training programme.
Exergaming is a relatively new treatment concept and is thought to increase motivation and enjoyment for users.
The Nintendo Wii has a built in pressure sensor that allows for feedback to be delivered to the user on their performance. There is evidence that a Wii based balance exercise programme could improve balance ability in the frail elderly population, so as a result, Fu and colleagues conducted research into whether this would transfer to reducing fall risk and incidence.
Sixty participants aged 65 or over received balance training three times per week for six weeks. They were randomly allocated into the intervention group who undertook balance activity on the Wii, or the control group who received conventional exercise. The results showed that while both groups reduced their risk and incidence of falls, the intervention group showed a more significant improvement.
The Wii balance training has shown to reduce falls by 69% compared with conventional training. Additionally, the intervention group had a 35% improvement in the fall risk score, considerably greater than that of the conventional balance training at 11%. As a result, the use of the Nintendo Wii for balance re-education is highly recommended and perhaps this suggests the need for further research on various other computer games available.
Tai chi is a newly emerging exercise incorporating breathing, relaxation and slow and gentle movements with strengthening and balance exercises. Whilst originally an ancient 13th century Chinese martial art, it has recently become more prevalent around the world as a health-promoting exercise. Whilst there is room for more rigorous research on the health benefits of tai chi, it is thought that it could help adults aged 65 and over in improving balance, reducing stress and controlling osteoarthritis pain. Additionally, in a high quality systematic review, tai chi was not only found to significantly reduce rate of falls, but also lessen risk of falls. As tai chi is considered a low impact exercise, it is suitable for most to participate in and should be considered as a treatment option.
Declining muscle function in older adults reduces their ability to rise from the floor following a fall and up to a half of all non-injured fallers are unable to get up. When someone is unable to get up off the floor unassisted, the associated risks are far greater due to the complications that can occur from lying on the floor for an extended period of time – for example, dehydration, hypothermia, pneumonia, pressure sores, unavoidable incontinence and even death. This inability to get up has a poor prognosis in terms of hospitalisation and mortality, thus, a long lie is one of the most serious consequences of a fall. The responsibility of the physiotherapist is to ensure the patient has a plan should they fall and are unable to rise and educate them about available strategies to combat this.
Backward chaining is a method utilised to re-educate patients in rising from the floor unassisted. It consists of a sequence of movements combined together to help teach someone to be able to get down to the floor safely. Once learnt, the sequence is reversed and is applied to teach a safe and effective way to get up from the floor. The movement is broken into several stages depending on the patient’s ability. The patient will complete one stage, then return to a stand. Then they will add on the next stage and return to a stand. This is repeated until the patient is able to stand from lying on the floor.
The effect of backward chaining on an individual’s ability to rise unassisted from the ground has been proven to be beneficial. In the only study to compare backward chaining with a control of conventional therapy, it was found that the backward-chaining method significantly enhances ability in rising after an incidental fall (20-40%). The control group showed no improvement. The study took part over 12 weeks and included 120 participants aged 80-99. Additionally, Timed Up and Go and Tinetti measurements were also compared before and after the intervention and control and a notable improvement was only observed from the intervention group. This highlights the benefits for improving functional capabilities in addition to rising abilities.
Fear of Falling
The prevalence of fear of falling in community-dwelling older adults ranges between 12% and 65%. Whilst it frequently occurs after falls, it is also established in those without a fall history. It can lead to a loss of independence, activity restriction and ultimately a poorer quality of life. Not all will avoid ADLs due to fear but for those who do, it can have debilitating and devastating effects. Lethem et al introduced the psychiatric concept of a fear avoidance model and is it is commonly utilised in the prevention of acute musculoskeletal pain becoming chronic. However, the hypothesis behind the model can be adapted to explain fear of falling and avoidance of activity. Extreme avoidance can lead to a decline in physical function, and ultimately an increased risk of falls, further fuelling fear and avoidance of activities. This is illustrated in the below fear avoidance model, adapted from Lethem et al.
The physiotherapist is in an ideal position to steer the individual towards the route of confrontation and recovery as opposed to activity avoidance and disability. There is high quality evidence from two systematic reviews highlighting the benefits of treatment to improve confidence and reduce fear of falling. Recommended interventions include: exercise, including tai chi, and multi-component falls prevention programmes.
Multi-Component Falls Prevention Programmes
As most falls are multifactorial in origin, they usually require several interventions. Such interventions typically involve a combination of medication review and optimisation and education, environmental modification and exercise. This type of programme would be delivered by a multidisciplinary team in which the physiotherapist would be a key member. A Cochrane systematic review suggests that the physiotherapy treatment should combine all elements mentioned above; that is strengthening, balance, backward chaining, tai chi and confidence building with education, tailored to each individual. Clinic-based group exercise or individual exercise in the home setting is suitable. However, further research is needed into the effectiveness of medication management in preventing falls.
Additionally, in a systematic review, it was reported that for the greatest effect, exercise programmes should include a high level challenge to balance, alongside strength and walking training. However, brisk walking training should not be prescribed to those at a high risk of falls. Furthermore, it was found that exercise should not only target those at high risk but also the general community and it should be performed for at least two hours per week on an ongoing basis.
Self-Management. Emergency hospital admissions is a major concern for the NHS. There are a number of factors associated with increased rates of admission including area of residency, ethnicity, socio-economic deprivation and environmental factors. Older people are also identified as being at a higher risk of hospital admittance.
In Scotland, 40% of the population have at least one long term condition (LTC). People with LTCs and co-morbidities are known to have poorer clinical outcomes, poorer quality of life and longer hospital stays. The Scottish Government reports that people with LTCs are twice as likely to be admitted to hospital. The ageing population and the increased prevalence of LTCs requires healthcare professionals to move their focus towards preventative strategies and empowering self-management.
Physiotherapist's have a role in promoting self-management of long term conditions and physical activity. Disease-related self-management abilities such as taking medication and exercise are often promoted by health care professionals. However, there may also be a need for interventions aimed at self-management of overall health and well-being to contribute to healthy ageing. Older peoples’ abilities to self-manage the effects of the ageing process depends on physical, psychological and social aspects of their life. Physiotherapists working with frail older people could play a role in promoting healthy ageing. Evidence shows that interventions to promote healthy ageing can be used to the delay the onset of frailty and reduce its adverse outcomes among older people.
As older people often have co-morbidities leading to a mixture of physical and psychosocial issues, self-management interventions should focus on providing them with general behavioural and cognitive skills for dealing with range of problems, rather than focusing on health-related problems only. It is outwith the scope of this learning resource to go into detail about how to promote self-management strategies as you are likely to see a range of diverse patients presenting with multiple conditions and challenging psychosocial issues. Your treatment plan will depend on the patient's presenting condition. However, as physiotherapists, we believe our main role within self-management can be to promote physical activity to contribute to the healthy ageing process.
Resources for patients
Functional capacity declines with age and this is further accelerated by low levels of physical activity.
The recommendations for physical activity for older adults (65+):
- Older adults should aim to be active daily
- At least 150 minutes a week of moderate intensity activity
- Muscle strength training twice a week in addition to the 150 minutes of activity
- Balance training and co-ordination should be incorporated into activities to manage risk of falls
- Minimise sedentary time
Physical activity significantly decreases with age. The graph below shows the percentage of men and women meeting the physical activity recommendations in Scotland.
Benefits of Physical Activity in Frail Older Adults
Strength, endurance, balance and bone density is lost at a rate of 10% per decade, while muscle power reduces at around 30% per decade. Sarcopenia is highly prevalent among older adults and has been identified as a risk factor for frailty. Being physically active slows down these physiological changes associated with ageing. Physical activity can also reduce the risk of falls, promote cognitive health and self-management of chronic diseases. It can also slow down the deterioration in ability to perform ADLs and maintain quality of life in older adults. A meta-analysis found that exercise is beneficial to improve balance, gait speed and abilities to carry out ADLs in the frail older adult population.
Factors Influencing Participation in Physical Activity in Older Adults
Older peoples’ participation in physical activity can be effected by biological, demographic, physiological and social factors. These factors are important to be aware of when attempting to motivate older people to increase their activity levels.
- Men are more active than women
- A decline in physical activity with age is higher among: minority ethnic groups, those from lower socio-economic backgrounds, those with lower education and those living alone
- Older people might be less able due to pain, reduced mobility and the need of assistance to mobilise
- Physical activity can be influenced by trusted others such as health care professionals, care givers, family and friends
- Lack of transport often affects older people's abilities to part take in activity
Psychological Factors That Can Positively Affect Participation
- Beliefs and confidence in abilities to be active
- General values, beliefs and attitudes
Psychological factors that can negatively affect participation
- Fear of falling and over exertion
- Safety concerns
Physiotherapists Role in Promoting Physical Activity in Frail Older Adults
Due to their training and experience, physiotherapists are in a good position to promote health and well-being of individuals and the community through education on physical activity and exercise prescription. Recently there has been a shift in the general public's health agenda towards the prevention of chronic conditions and enabling the ageing population to stay active and manage conditions in the community. This has required a change in the role of the physiotherapist towards addressing these issues through promotion of physical activity and other lifestyle changes. When encouraging physical activity, physiotherapists should also aim to:
- Identify fears and barriers to being physically active and provide solutions to overcome these
- Provide ongoing support and encouragement
Exercises for Frail Older Adults
These are the recommended activities and intensity for frail older adults to increase physical activity. These aim to improve general health and well being, as well as reduce the risk of falls and manage chronic lifestyle conditions:
- Sessions as short as 10 minutes can provide health benefits
- Frail older adults should aim to accumulate numerous 10 minute sessions to achieve the recommended activity guides
- Take the stairs
- Do housework or gardening
- Tai Chi
- Home-based or group exercise classes
- Breaking up time spent sitting with short regular periods of standing or walking
- Encourage to move for longer. E.g. Going from moving 5 minutes to 10 minutes may increase the intensity
achieving a goal. Motivation often stems from a need we must fulfil and this leads to a specific behaviour. In 1943, Maslow developed a theory of human motivation aiming to explain and rank all types of human needs. Maslow’s Hierarchy model is made up of five levels ranked in importance with the most basic needs at the bottom. In order to progress up the hierarchy, the lower needs must be fulfilled.
Depending on your preferred ways of learning, choose if you want to read or watch the video below to learn more about the Maslow’s Hierarchy.
There are many factors that motivate the elderly to participate in exercise programs, see below. supports this idea of goal setting within the elderly population. Without goals, adherence to exercise is limited. The literature again reinforces the fundamentals of effective goal setting:
- Patient-centred goals
- Small goals incrementally increasing to large goals e.g. short term and long term
- Should adhere to SMART principles
Despite the need to motivate it is also important to listen to the patient and their needs. One of the ways we can encourage motivation is by arranging a group exercise class, as this not only promotes the physical benefits of exercise, but allows participation in a social gathering. Furthermore, research suggests that people are more likely to exercise if they have a companion.
The average age of the population is increasing and it is suggested that the prevalence of frailty will multiply. Subsequently, there has been a shift of care from reactive to preventative strategies and a focus on providing early interventions to reduce costly unplanned admissions to hospital. Several guidelines are available, but none specifically detail the physiotherapist's role.
