Telerehabilitation and Smartphone Apps in Physiotherapy

Introduction[edit | edit source]

The rapid evolution of technology has allowed health professionals to begin to adapt to these changes and deliver healthcare in a new, remote fashion. More recently, mHealth has come into play, which refers to the concept of using mobile devices, such as phones, tablets and smartphones in both medicine and public health [1]. mHealth is seen as an enabler of change worldwide because of its high reach and low-cost solutions [1]. The change towards technology-based practice and more specifically smartphone-based applications is an extremely relevant area for health professionals to effectively communicate and treat a variety of patient groups. Therapeutic compliance has been a topic of clinical concern since the 1970's due to the widespread nature of non-compliance with therapy and rehabilitation programs [2]. It can be proposed that these recent advances in technology can help improve therapeutic outcomes. 

Specific to physiotherapy home exercise programs, smartphone applications provide a new and emerging way to deliver physiotherapy that promotes active participation from both the physiotherapist and patient throughout the course of treatment.

Overview of Telerehabilitation[edit | edit source]

In recent years, technology has revolutionised all aspects of medical rehabilitation, from developments in the provision of cutting edge treatments to the actual delivery of the specific interventions [3]. Telerehabilitation refers to the use of information and communication technologies (ICT) to provide rehabilitation services to people remotely in their home or other environments [3]. Such services include therapeutic interventions, remote monitoring of progress, education, consultation, training and a means of networking for people with disabilities[4].

Using technology to deliver rehabilitation services has many benefits for not only the clinician but also the patients themselves. It provides the patient with a sense of personal autonomy and empowerment, enabling them to take control in the management of their condition [3]. In essence they are becoming an active partner rather than a passive participant in their care. It enables access to care for individuals in remote areas or for those who have mobility issues associated with physical impairment, access to transport and socioeconomic factors [4]. In addition, it cuts down the associated travel costs and time spent travelling for both the healthcare provider and the patient [5]. Research has found that the rehabilitation needs for individuals with long-term conditions such as stroke, TBI and other neurological disorders are often unmet in the patient’s local community [4].

As telerehabilitation expands, patient continuity of care improves. It enables clinicians to remotely engage and deliver patient care outside of the medical setting, thus eliminating the issue of distance between clinician and patient [3]. This opportunity to continue rehabilitation within the patient’s own social and vocational environment should lead to greater functional outcomes [6].

The shift in the global demographics towards an increasing elderly population brings with it an associated increase in chronic health conditions [7]. This highlights the need for changes to be made in the delivery of rehabilitation services with the incorporation of self-management strategies and technology. The predicted growth in the elderly population, individuals aged 65 and over, by 2035, will account for 23% of the total population in the UK [8].

Growing numbers of elderly people have an impact on the NHS, incurring considerable health costs due to the growing demand for treatments [9]. It is hoped that by integrating telehealth measures, these costs will be reduced. Kortke et al (2006) found a significant improvement in patient outcomes when using telerehabilitation with a 58% reduction in cost in comparison to in-patient rehabilitation [10].

Generally, most systematic reviews that have been carried out investigating the efficacy of telerehabilitation report the patient’s perspective on its use as a positive experience with significant clinical outcomes [11]. The hope for the future is to continue to develop and use new, innovative technologies that will transform current practice and make telerehabilitation an integral part of healthcare [4].

Progression of Technology[edit | edit source]

Telerehabilitation for physical disorders has been short-lived. The problems that arose for this type of rehabilitation stemmed from the difficulties it imposed on the so-called “hands-on” therapies, particularly physiotherapy and occupational therapy [4]. However, as technology has progressed in healthcare, the possibilities for effective telerehabilitation in therapies such as these have improved.

Early research into telerehabilitation was introduced with small pilot studies. In some of the first projects, clinicians used the telephone to provide follow up and to administer self-assessment measures [12]. From this, telerehabilitation continued to progress into the 1980s with pre-recorded video material for client use and interaction [13].

Eventually, live interactive video conferencing was introduced [14]. The potential uses for video conferencing in healthcare and telerehabilitation became apparent in the 1990s with many projects being carried out in physiotherapy. In a randomised control trial (RCT) by Russell and colleagues (2011), the efficacy of this internet-based telerehabilitation system was assessed versus conventional physiotherapy in the provision of outpatient rehabilitation to patients who had received total knee replacement (TKR). Comparable results were reported with the two rehabilitation methods and patients were satisfied with the telerehabilitation treatment provided [15].

The use of videoconferencing allows for the provision of consultations, diagnostic assessments and delivery of treatment interventions as well as providing verbal and visual interaction between participants. However, problems lay initially in the inability to measure participant’s physical performance; for example in physiotherapy, these would include measures such as range of motion and gait. This was soon overcome by measurement tools that were able to objectively quantify participant’s physical performance [4]. Developments continued to be made using sensor and remote monitoring technologies for within the home which further enhanced the benefits of these new innovative technologies of telerehabilitation [3]. These developments provided a means of home-based exercise monitoring by the patient and the rehab professional while also enabling the professional to track patient compliance to specific exercise programmes [16].

Virtual environments are another technological method introduced to healthcare. These allow users to interact with computer generated environments in real time [4]. Virtual reality begins with real world scenes which are then virtualized, thus mimicking real world environments [17]. It enables healthcare professionals to design environments which can be used in areas such as surgery, physical rehabilitation and education and training.

In recent years, smartphones have revolutionised communication within the medical setting. This modernisation is allowing the opportunity to provide medical support when and where people need it.  Recently, it has been reported that half of smartphone owners use their devices to get health information [18], with one fifth of smartphone users actually using health related applications (apps) [19]. There are a wide range of mobile apps available for healthcare professionals, medical students, patients and the general public [20].

Applications for Specific Conditions[edit | edit source]

In the innovation of mobile technology, mHealth (mobile health) in particular is helping with chronic disease management, empowering the elderly, reminding people to take medication at the right time, undergo scheduled exercise, extending service to underserved areas and improving health outcomes [21]. There is currently a vast range of mobile apps, interactive tools and podcasts that cater to an array of healthcare conditions and disabilities both formal and informal, recognized and promoted by the NHS [22]. In 2012, there were an estimated 40,000 health-related apps available [23]. Those formal in nature allow patients to record and send health measures and send them electronically to physicians and/or specialists.

As such the National Delivery Plan 2012 documents that by deploying technology in healthcare “provides an opportunity to treat patients in new ways and helps manage rising costs and demand” [24]. Theoretically, this allows for greater access to healthcare provisions, availability of care and supports self management and prevention in routine care, thereby reducing unnecessary admissions (therefore speeding up the treatment of patients requiring medical intervention) and helps to reduce healthcare costs in an aging population [25].

Currently, there are a number of generic healthcare apps available for download which cater for many different acute and chronic conditions. Which have either been approved by the NHS or the private sector. Not only that, but there are also many that function as self assessment, screening and testing tools and symptom checkers, goal setters and treatment/exercise logs and prescribers. Others are collections of support videos or advice.

Using Smartphone Applications in Physiotherapy[edit | edit source]

Following an understanding of what motivates patient behaviour and adherence to healthcare treatments discussed above, this section will look more specifically at factors that have an impact on the patient’s ability to respond and agree to treatment in the form of home exercise programmes (HEPs) as well as the potential for healthcare and physiotherapy smartphone applications to deepen the patient-physiotherapist relationship and improve overall rehabilitation of the patient in a musculoskeletal setting. 

In an outpatient setting, a HEP is tailored to an individual patient and targets their specific problems, as identified by the Physiotherapist. This exercise schedule, modified with repetitions, sets and/or additional strengthening/ endurance components, is to be performed by the patient in their home environment between treatment sessions with the Physiotherapist. Continuation of training at home ensures that a patient will begin to improve and that their progress can be monitored throughout time. The continued tailoring of the HEP from each session by the physiotherapist must be complemented by the patient’s continued determination and trust in their shifting programme. The understanding and commitment between both the patient and their physiotherapist to achieve both short-term and long-term goals indicates a better outcome for the patient once they are back to (or potentially better than) their baseline. However, various reports monitoring patient compliance with and to a HEP show non-adherence rates to be as low as approximately 20% ([26]; [27]).

In addition to factors and models described above such as goal setting, self-efficacy, intrinsic and extrinsic motivation (self-determination theory) and the transtheoretical model there are other circumstances which can affect the ability of patients to respond positively to a home exercise programme. While demographics such as age and gender have been shown to have little effect on these rates ([26]), there are a few factors that have been discovered and discussed in the research that may affect compliance such as:

  • Low levels of physical activity at baseline
  • Anxiety, depression and pain
  • Poor social support
  • Greater perceived barriers to exercise
  • Poor understanding about their condition
  • Difficult to commit to the time needed to exercise
  • High cost of treatment

Through a greater understanding of the patient perspective, Physiotherapists alongside the multi-disciplinary team can work to target and ensure that patients are kept on the right track and allow greater improvement of quality of life. However, with an adherence rate of 20% keeping most patients isolated from full recovery, what can we do to strengthen the patient-physiotherapist relationship?

This is where the potential of telerehabilitation comes in. Discussed in the beginning sections, telerehabilitation is the modernization of healthcare-related treatments and services. Mobile technologies are still fairly recent and just starting to emerge; therefore there is not a wealth information or research on their use or advantages.

Data Protection[edit | edit source]

With the increasing number of smartphone applications and rapid progression of telerehabilitation services available worldwide, it is important the the physiotherapist is aware of the quality and protection that the software offers. In the UK, compliance with the Data Protection Act is a minimum standard to protect your information and rights. The following table describes key rules so that information is:

(Scottish Government 2015)

Many applications provide a global sample of physiotherapy home exercise programs available through smartphone applications. Under the ‘terms and conditions’ and ‘privacy policy’ section of each application, they specifically describe data protection as well as liability concerns for using their software. Importantly, they all describe in some form that the company is not to be held liable for any health concerns that have occured while using the application. The physiotherapist must ensure that they are adequately insured.This is extremely important for the all applications, but specifically PhysioAdvisor as the patient can utilize resources to assist with self-diagnosis and have independent control over creating their own exercise program. It is important for both patients and physiotherapists to make themselves aware of the terms and conditions when using external applications.

Cost Effectiveness[edit | edit source]

The common occurrence of patients’ failing to attend scheduled appointments results in loss of revenue, underutilization of the healthcare system as well as prolonged waiting lists[28]. A smartphone application is a potential method to prevent cancellations through effective reminder systems. Each application costs a small renewable fee which is based on the number of physiotherapists and or clinics that require a subscription . Important to note is that therapeutic non-compliance has been associated with excess urgent care visits, hospitalizations and higher treatment costs [2]. These applications can be seen as an investment for the clinic or hospital to help increase efficiency, reduce cancellations and prevent future health care demand.[24]. While these applications provide an exciting new outlet for physiotherapy to proceed towards in the future, there are some barriers and limitations to the successful implementation of these new technologies. Through a discussion and understanding of these obstacles, further research can be directed at ways to improve and adapt technologies to suit the current needs of healthcare.

Concluding Remarks [edit | edit source]

With the ever enhancing realm of technology and mHeath applications, the future generation of physiotherapists must be aware of the evolving changes in technology to make physiotherapy an interactive environment with the patient. This will support an increase in motivation and facilitate participation in a home exercise program. As one review discovered, non-compliance remains a major issue in improving healthcare outcomes despite many studies highlighting this ongoing issue over the years [2]. The new face of physiotherapy applications can facilitate patient adherence by creating an interactive exercise environment that promotes self-efficacy and behavior change through enhanced communication, goal setting and progress reporting means. As this wiki has highlighted, there are many links that can be made between the models of behavior change and some of the smartphone applications discussed here, however due to wide variation in terms of study designs and applications, it is difficult to pinpoint potential influences of mobile-phone based strategies on physical activity behavior [29]. Additionally, the effectiveness of smartphone applications to improve health behaviours is an emerging field of research [30].

Government highlights for our way forward, we need to improve sustainability and value by establishing a baseline, and developing consistent outcome measures and indicators to track the impact of telehealth and telecare on working practices, productivity and resource use [24]. Future research is necessary to focus on these novel physiotherapy applications and the effect on patient behavior change and patient experience. Research should also target physiotherapy programs administered via these applications to identify any advances in rehabilitation and home exercise programs.
