Introduction

Physical inactivity has been deemed "the biggest public health problem of the 21st century" and has been shown to kill more people than smoking, diabetes and obesity combined (Figure 1). It is ranked as the fourth leading risk factor for global mortality, killing approximately 3.2 million people (~6% of the total deaths) annually and accounting for approximately 32.1 million disability adjusted life years (DALYs; ~2.1% of global DALYs) annually.

Sedentary Behaviour

As emphasised in the video 23 and ½ Hours and embraced by the latest physical activity guidelines, the ‘dose’ of physical activity that seems to confer the majority of these health benefits (in adults) is 30 minutes of moderate to vigorous intensity on most days of the week. However, one aspect of physical activity promotion that this dose recommendation does not address is sedentary behaviour. See Sedentary behaviour link.

Given the amount of time potentially spent sitting each day evidence suggests that short breaks in sedentary time can confer substantial health benefits , as highlighted in the short video below.

Is Sitting On Your Backside Dangerous?

Thus, it is clear that the physical activity paradigm should incorporate sedentary behaviour, and physical activity initiatives and recommendations should adapt accordingly .

The Development and Evolution of Physical Activity Guidelines

Beginning with Morris’ work on occupational physical activity in the 1950s , the evidence emerging from the years of epidemiological research of the risks associated with inactivity or a sedentary lifestyle provided the rationale for the development of physical activity guidelines. Identifying the appropriate ‘dose’ of physical activity that would extract the greatest reward in public health requires an ongoing examination of data emerging from both epidemiological and exercise training studies. It also requires the decision to focus these recommendations on the population who would benefit most, namely those who are inactive, thus contributing to the public health burden.

Physiotherapists have the potential to make a substantial impact on individual, community and public health. Their holistic, biopsychosocial, and non-invasive approach, professional autonomy, specialist knowledge and skill set, relatively prolonged patient contact time and varied clinical practice populations and settings (including prisons) places the physiotherapist in the ideal position for the widespread promotion of physical activity (Figure 9).

Figure 9. Summary of why physiotherapists are in an ideal position to take the lead as 'physical activity champions'. (Figure adapted from Europa 2012 [presentation])

In the past, physiotherapy intervention, including exercise prescription, has predominantly focused on the restoration of function lost as a result of an acute incident or on the maintenance of function in neurological or cardio-respiratory disease. However, a shift in the public health agenda towards the prevention or management of chronic lifestyle conditions, including NCDs, obesity, osteoarthritis and depression, and towards the mitigation of the effects of ageing in an increasingly ageing population has demanded a change in the role of the physiotherapist in addressing this need through the widespread promotion of physical activity (and other health-promoting lifestyle changes). Recognising this emerging role and “professional and ethical responsibility”, physiotherapy professional bodies around the world have brought physical activity promotion to the forefront of their agenda with links to two clear examples - CSP and WCPT - provided below.

Physical Activity For The Individual

Physical activity promotion at the level of the individual is not a novel concept. As first points of contact, primary care providers, particularly GPs, have acknowledged a necessary role in physical activity promotion for decades, with varying degrees of follow-through in different countries. The various medical-practitioner-based physical activity schemes developed have typically involved (1) links to commercial exercise centres; (2) the provision of simple advice on physical activity or (3) a behavioural counselling approach to the provision of physical activity advice.

Assessing Physical Activity

Assessment is an important tool in the physiotherapist's arsenal, enabling the collection of relevant information for a clinically-reasoned, holistic and patient-centred approach to diagnosis and subsequent management. Despite the evidence, patients’ habitual physical activity and sedentary levels are generally not assessed as part of the standard physiotherapy assessment.Yet, all patients coming into contact with a physiotherapist suffer from and/or are susceptible to the effects of physical inactivity, regardless of their presenting complaint. Thus, the assessment of physical activity and sedentary levels has a relevant place in the physiotherapy examination.

In the general medicine community, physical activity has been declared the fifth vital sign – a modifiable sign that should be assessed at every clinical encounter. Different approaches may be used to measure levels of physical activity (e.g. observation, heart rate monitors, motion sensors), but questionnaires are likely to be the most appropriate in the context of a typical physiotherapy assessment, given time and resource constraints. Three alternatives for the assessment of a patient’s physical activity levels are described below.

The Kaiser Permanente Approach: The ‘Exercise Vital Sign’

Kaiser Permanente is a not-for-profit, California-based integrated managed care consortium that have adopted a simple method for assessing physical activity levels in each patient, at every visit. Coined the ‘Exercise Vital Sign' (EVS), it is a brief screening tool that consists of two questions and has shown good face and discriminant validity. It is described in the 40-second video below.

Kaiser Permanente: Making Exercise a Vital Sign

Key Points: The EVS: "2 questions, 1 minute"  1) “On average, how many days per week do you engage in moderate or greater physical activity?”   2) “On those days, how many minutes do you engage in activity at this level?”

Mobilising Behaviour Change

Physical activity is a complex, multifactorial (Figure 3) and multi-dimensional (Figure 7) health behaviour. The role of the physiotherapist in counselling a patient to adopt, change or maintain such a behaviour can be equally complex. It may involve forming a partnership with the patient, defining the target behaviour (e.g. increasing physical activity and decreasing sedentary behaviour), exploring and addressing the unique combination of personal, socio-cultural, environmental, policy factors underlying the patient’s behaviour and identifying the most suitable (patient-centred) approach(es) to mobilise and help the patient sustain the behaviour. Long-term adherence to physical activity is essential for the health benefits to be realised.

Several theoretical models of and counselling approaches for health behaviour change have been developed. A working knowledge of these models and the various approaches to their practical application is another essential tool in the physiotherapist’s arsenal, if s/he is to help effect and sustain behaviour change in the patient.

A summary of these models and approaches is provided below.

Theoretical Models of Health Behaviour Change

Table 2 provides a brief description of and practical suggestions for some of the most prominent theoretical models. Among these, the Transtheoretical Model (TTM) has received the most attention in the field due to its ease and utility in clinical practice. It assumes that a patient’s readiness to change falls within one of five stages, based on his/her level of engagement with the particular health behaviour

Determining the patient’s stage of readiness through a series of specific questions facilitates the identification of strategies or subsequent interventions that will be most effective in guiding the patient to progress to the next stage . The Health Behavior Change Research (HBCR) workgroup at the University of Hawai’i at Mānoa provide a series of relevant questionnaires for applying the TTM to physical activity. The American Council on Exercise® (ACE) offers practical guidance on how to use the TTM to help a patient make healthy behaviour changes. Links to both the HBCR and ACE are provided below. In particular, motivational interviewing, has gained wide acceptance as an effective means of motivating behaviour change within the TTM framework.

Methods to Promote Behaviour Change

Behavioural counselling encompasses a spectrum of interventions, which can be rooted in one or more behavioural theories. Two approaches - Brief Advice and Brief Intervention - do not require extensive training to be effectively executed

Brief Advice 

Brief Advice consists of a short (~3 minute), structured conversation with the patient aimed at raising awareness of the benefits of physical activity, exploring barriers and identifying some solutions. It may be suitable for a patient in the early stages of readiness, namely precontemplation and contemplation, or for a patient in the maintenance stage, requiring only reinforcement to maintain the behaviour. 

Brief Intervention

Brief Interventions are longer (~3-20 minutes), structured conversations, which delve deeper into the patient’s needs, preferences and circumstances with the aim of motivating and supporting the patient toward the behaviour change in a non-judgmental and positive manner. More time is spent discussing the benefits of the behaviour change, addressing barriers, setting goals and building confidence.

Motivational Interviewing

Motivational interviewing is a behaviour change intervention that has been most recently defined as “…a collaborative, person-centred form of guiding to elicit and strengthen motivation for change”. See link.

Physical Activity 'On Prescription'

Having assessed the patient’s physical activity levels and having begun to develop a behavioural approach and partnership with the patient, the final major component of physical activity promotion at the level of the individual is the actual substance of the intervention – the health education, physical activity prescription and other ‘stuff’ received by the patient to be able to adopt and/or maintain a more physically active and less sedentary lifestyle. Interestingly, while it is generally acknowledged that physiotherapists have a significant role in health promotion and prescription, physiotherapists’ perceptions of this role varies. The next few subsections provide relevant information intended to facilitate physiotherapists in achieving this role.

Education

Patient education has become an essential part of health care for the patient, enabling him/her to participate in the decision-making. Critically, it is also the responsibility of physiotherapists to educate their patients. Given their unique patient contact and broad patient access (Figure 9), they are advantageously positioned to do so – in every patient, across the lifespan and among all settings. Furthermore, education as a physiotherapy intervention has proven to be successful for the management of low back pain and other conditions, with a recent report of patient waiting times being cut by half as a result of a patient education pilot.

Thus, by combining effective education, which should be tailored in content and delivery to the patient’s individual learning needs, and the principles of behavioural change, physiotherapists have the potential to achieve:

• Increased knowledge and awareness of risks of physical inactivity and the benefits of physical activity.
  
• Increased knowledge and awareness of physical activity, what it can entail and how it can be achieved, including use of the services available, hence increasing self-efficacy and potentiating adherence to a new lifestyle.
• A change in attitudes and motivations for engaging in physical activity.
• A change in beliefs and perceptions about physical activity, sedentary behaviour and social norms.

Summary

Figure 16. Illustration of the process of the physical activity prescription in the context of the ICF.

While this section on physical activity promotion at the level of the individual has been presented in a linear or sequential fashion, the phases are intertwined and continuous (Figure 16). The assessment of physical activity and stage of readiness and the provision of the prescription occur using a relevant behavioural counselling approach in the context of the patient’s biopsychosocial status, as guided by the International Classification of Function and Disability (ICF).

In forming a partnership with the patient, the physiotherapist aims to understand the barriers preventing the patient from engaging in a more physically active lifestyle and begin to consider ways in which the patient may negotiate them. These barriers are not only the practical ones, such as time and equipment, but also physical and mental. In particular, identification of the patient’s physical and mental barriers, including disease or disorder, and proper, ongoing risk assessment (e.g. PAR-Q) in the process of physical activity promotion is essential and the essence of why physiotherapists are ideal candidates for this role. While risk assessment is essential it falls outside the scope of the current topic but with regards to promoting physical activity in the the following groups:

• Individuals who are healthy but sedentary.
• Individuals that are apparently health and sedentary.
• Individuals with comorbidities.
• Individuals with a disability.

The same fundemental rigour of safe and competent practice remains unchanged from the policies set out by the CSP and HCPC.

Ultimately, three key issues will challenge the physiotherapist and the patient:

1. Uptake of adequate levels of physical activity
2. Adherence to adequate levels of physical activity and avoidance of relapse
3. Avoidance of prolonged periods of physical inactivity

Finally, it is important that clinicians avoid the assumption that:

• “If you recommend exercise, they will do it…”
• “If you write a programme, they will follow it…”

Support, guidance and follow-up are critical to the maintenance of the patient’s physical activity behaviour. Guides and leaflets, such as those produced by the CSP (below), are options of support that may be provided.

Physical Activity Beyond The Individual

The emergence of physical activity at the heart of the public health agenda has unveiled unforeseen opportunities and unprecedented roles for physiotherapists.

See Physical Activity Promotion in the Community

Volunteering 

In general, volunteering is an ever-emerging role for physiotherapists. It can entail anything from volunteering locally to travelling abroad.

Home:Physiotherapists can volunteer in their local communities in various ways from programme administration to teaching classes in the promotion of physical activity.
                                       Abroad: With rising prevalence in physical inactivity and the rising need of NCD prevention and control in underdeveloped nations, the need for targeted physical activity promotion is being realised, and the value of volunteering for initiatives such as GAPA cannot be dismissed. In addition, it has been estimated by the United Nations Development Programme that over 80% of the world’s 650 million disabled people reside in impoverished countries with little access to rehabilitation facilities, education, and employment. Overseas organisations are constantly looking for physiotherapists for the promotion of health and the development of rehabilitation services both in hospitals and in community-based clinics.

Conclusion

The Resource was created as a guide for physiotherapists and others interested in the physical activity agenda. Collating information from various sources in various media formats, it provides an overview of the relevant underpinning evidence supporting physical activity as a public health priority and the means by which it may be addressed. In particular, it focuses on the significance of the role of the physiotherapist in the promotion of physical activity at the level of the individual, in the community and in government and policy. Within each section, it offers relevant guidance and useful tools. It also offers suggestions for relevant further reading and CPD opportunities to encourage further exploration and consolidation of learning. In conclusion, given the significance of the role of the physiotherapist in the physical activity agenda, one issue remains and calls for further reflection.
