Adherence and outcomes: is personal physical activity the missing pillar of physiotherapy rehabilitation?

In the field of physiotherapy, one truth is becoming increasingly clear from a scientific standpoint: what you do between your sessions matters just as much as what happens during them. This is also true in any field relating to health. Whatever the problem being treated: chronic pain, post-operative rehabilitation, neurological disorder or prevention of relapse, your personal physical activity level is one of the most decisive factors in your recovery.

This article is for everyone: patients undergoing rehabilitation, healthcare professionals, injured athletes, older adults losing independence, or simply anyone curious to understand why movement is, quite literally, medicine. You will discover the scientific evidence, the concrete mechanisms, and immediately applicable strategies to make your body an active ally in your healing. For curious therapists, we will also give you some points for reflection on the benefits that Andrew® can bring you in this setting.

Active vs passive rehabilitation: why is the patient the main driver?

The myth of passive rehabilitation

For decades, rehabilitation was thought of as something you endure: expert hands that mobilise, machines that stimulate, electrodes that work on your behalf. This so-called passive model remains useful in certain acute phases. But the scientific evidence is clear: it is not enough.

Active rehabilitation - the one in which you take part, move and exercise - produces significantly superior clinical outcomes in the long term. And the international data available in the field of rehabilitation and physiotherapy confirm this.

The scientific evidence

• A systematic review published in Disability and Rehabilitation analysed the predictors of adherence to home rehabilitation programmes. It shows that patients who maintain a regular exercise programme between sessions achieve clearly better outcomes than those who passively wait for their next appointment. (1)

• Similarly, a study published in 2010 in Arthritis Care & Research involving patients with hip or knee osteoarthritis shows that strong adherence to an exercise prescription is directly associated with better long-term outcomes, including pain and quality of life. They emphasise one essential point:

'Adherence to the exercise programme is one of the strongest predictors of lasting functional recovery, across all conditions.' (2)

• For neurological conditions, the results are just as convincing. The LAST study, conducted on post-stroke patients, shows that those who followed the personalised physical activity programme recovered their motor and functional abilities significantly better than non-adherent patients. (3)

What science clearly says: personal physical activity is not a 'bonus', it is a therapeutic pillar in its own right.

Biological mechanisms: why movement repairs

The human body is designed to move

Human beings are not meant to remain still. Our tendons, muscles, bones and cartilage need regular mechanical loading to maintain their integrity. Prolonged immobilisation, even partial, triggers a cascade of harmful effects: muscle atrophy, joint stiffness, reduced bone density, increased chronic pain.

By contrast, adapted exercise triggers a series of repair processes that no medicine can reproduce on its own.

The 5 major biological effects of physical activity

• Neuroplasticity and motor recovery: repeated movement creates and consolidates new neuronal connections. This is the fundamental principle of recovery after a neurological injury (stroke, traumatic brain injury). The more you practise, the more the brain reorganises its circuits.

• Tendon and muscle remodelling: progressive mechanical loads stimulate collagen synthesis, strengthen tendons and increase muscle cross-sectional area. This is why eccentric strengthening programmes are so effective in tendinopathies.

• Reduction in central sensitisation: regular physical activity modulates pain pathways by releasing endorphins and reducing inflammatory markers. It acts directly on pain, which is especially relevant for chronic patients. To support this point, you can find our study conducted on more than 600 patients with low back pain using Andrew® in collaboration with stane.

• Cardiovascular and metabolic improvement: even outside cardiac conditions, exertion improves tissue oxygenation, speeds up the removal of metabolic waste and promotes healing.

• Psychological impact: anxiety, depression and fear of movement (kinesiophobia) are major barriers to recovery. Physical activity is one of the most effective interventions for reducing them, with a direct effect on the patient's motivation and independence.

Adherence: the most underestimated factor in rehabilitation

Why do patients drop out of rehabilitation?

The scientific literature on rehabilitation is clear: adherence to exercise programmes is low. Some studies estimate that between 30% and 70% of patients do not carry out their home exercises properly. Yet this is precisely where the bulk of recovery happens.

The reasons for this drop-out are numerous and well documented:

• Lack of understanding: the patient does not know why they are doing the exercise, so they do not do it.

• Fear of pain: if poorly informed, they confuse productive pain (good) with dangerous pain (to be avoided).

• Lack of follow-up: between two sessions, they receive no feedback on progress and no possible correction.

• Lack of progression: exercises that are too easy become boring, exercises that are too hard are discouraging.

• Simple forgetfulness: without reminders or a tracking tool, exercise quickly becomes an abstraction.

Avoid these mistakes with Andrew®.

Which strategies work to improve patient adherence?

The 2016 systematic review cited above (1) identifies several factors that significantly increase adherence to active rehabilitation programmes:

• Patient therapeutic education: explaining the mechanism, the 'why', is more effective than simply prescribing exercise. Be careful not to give the patient a lecture, as Rémy Olier would say.

• Personalising the programme: an exercise adapted to your daily life, your constraints and your goals is followed much more closely than a standard protocol.

• Regular follow-up and encouragement: the simple fact of being reminded by a professional or a physiotherapy app measurably improves adherence.

• Gradual empowerment: teaching the patient to become independent and to modulate their own effort is a long-term lever.

• Patient-centred goal: getting back to sport, playing with their children, walking without pain... concrete personal goals that motivate infinitely more than an abstract functional score.

Tools such as Andrew®, exercise prescription and therapeutic education software, allow physiotherapists to personalise programmes, share them clearly with their patients, and ensure remote follow-up via teleconsultation and the Andrew® Coach app. A time-saver for the practitioner, and a proven lever for patient independence.

Sport and rehabilitation: moving beyond misconceptions

'I must not push myself during rehabilitation'

This is one of the most common and most counterproductive beliefs. Kinesiophobia, the fear of movement linked to the fear of getting injured again, is a major obstacle to recovery, particularly after orthopaedic surgery or a muscle injury.

Yet the evidence is clear: a progressive, well-dosed load speeds up healing, prevents recurrence and improves final performance. Controlled movement is not the enemy of healing; it is its engine.

'I'm not sporty, so physical activity is not for me'

Physical activity in rehabilitation does not necessarily mean running a marathon or lifting weights. It can take the form of brisk walking, swimming, cycling, therapeutic yoga, gentle exercise or simple postural work. The key is regularity; intensity comes later.

Recommendations such as those from the WHO remind us that even 150 minutes of moderate activity per week produces measurable effects on overall health, functional recovery and the prevention of chronic disease.

High-performance sport and rehabilitation

For athletes, the challenge is different but just as crucial: regain the previous level of performance without rushing the return to play or unnecessarily prolonging the lay-off. The concept of Return to Sport (or Return to Play - RTP) is now a field of expertise in its own right, based on objective criteria (strength, proprioception, functional tests) rather than the patient's feelings alone.

Sports physiotherapists use validated protocols to make this return safe, and the structured physical activity between sessions is inseparable from their effectiveness.

How can physical activity be integrated into rehabilitation? Practical guide

Step 1: Define the rehabilitation goals

First of all, discuss together what you want to get back to. Walking 5 km? Returning to tennis? Playing with the grandchildren? These concrete goals will guide the design of your exercise programme.

Step 2: Understand each exercise

Never give/do an exercise without understanding its therapeutic logic. It is important to clarify: 'Why this exercise? What does it repair? How should it feel while doing it?'. A patient who understands is a patient who adheres.

Step 3: Integrate movement into daily life

Exercise prescription should not be an additional burden, but an integrated habit. A few practical strategies:

• Link exercises to an existing activity (after the morning coffee, before the evening shower, etc.).

• Use reminders on your phone or a dedicated app so you never forget.

• Record progress: a journal or an app such as Andrew® will make it possible to visualise improvement and maintain motivation.

• Start small, but start now. An extra 10 minutes of walking a day is already a change in direction.

Step 4: Listen to the body, but do not fear it

Distinguish between productive muscle soreness (mild aches after exertion, a sign of adaptation) and joint or inflammatory pain (a warning sign). If in doubt, the patient should contact their physiotherapist; that is exactly why they are there.

Step 5: Maintain physical activity even after rehabilitation

The end of treatment does not mean the end of activity. Prevention of recurrence relies on continuity of movement. A regular maintenance programme, even a minimalist one, significantly reduces the risk of relapse and preserves the gains achieved during rehabilitation.

The role of the physiotherapist: movement prescriber and educator

Much more than a manual therapist

Today's physio is no longer just a specialist in therapeutic touch. They are also a movement coach, a health educator, a motivator. Their role is to make the patient independent as quickly as possible, not to create dependence on their treatment.

This approach, based on the biopsychosocial model of health, recognises that pain and disability are not purely biological: they are also influenced by psychology, social context, beliefs and behaviours. That is why therapeutic education (explaining, reassuring, empowering) is now considered an essential component of any treatment pathway, especially in physiotherapy.

Exercise prescription: a medical act in its own right

Prescribing a programme of therapeutic exercises is not trivial. It requires precise assessment, knowledge of contraindications, adaptation to the patient's capabilities and rigorous follow-up. It is a clinical act, not a simple recommendation.

Modern digital tools such as Andrew® make it possible to formalise this prescription: explanatory videos, progress tracking, patient-practitioner communication between sessions. This type of approach improves patient independence, reduces readmissions and optimises clinical outcomes while enhancing the physiotherapy practice.

Physical activity, a universal therapeutic tool: beyond borders and conditions

One of the most remarkable things in the rehabilitation literature is how much the findings converge, regardless of the condition, the patient's age or the country in which practice takes place.

Whether you are:

• A patient with chronic low back pain in France,

• An older adult in post-fracture rehabilitation in Japan,

• An amateur footballer in ligament rehabilitation in Spain,

• A post-stroke patient in neurological rehabilitation in the United States,

The conclusion is the same: the more active you are in your rehabilitation, the better your outcomes. Physical activity is the only treatment that transcends geographical, cultural and clinical borders.

WHO recommendations, echoed and expanded by recent studies published in the International Journal of Behavioral Nutrition and Physical Activity (2025), confirm that regular physical activity is associated with a reduction in all-cause mortality, improved mental health and better post-illness recovery.

What you can do today (patient or healthcare professional)

The good news is that you do not have to wait for your next session to start acting. Here are 5 concrete actions you can put in place right now to maximise the impact of your rehabilitation

• (Make) move every day, even if only for 15 minutes. Regularity matters more than intensity.

• Review the exercises prescribed. Has the goal been understood? Have they been integrated into a routine?

• (Patient) Talk about your fears with your practitioner. Kinesiophobia can be treated and it is an essential step towards healing.

• Agree together on a personal and realistic goal for returning to activity. Not an abstract number, but an activity that you enjoy and want to get back to.

• Explore digital tools together that can support your programme between sessions: tracking apps, exercise videos, automatic reminders.

• (Physios) finally enhance your treatment pathways by offering your patients support programmes, coaching in HN alongside rehabilitation. Speak to a member of the team by clicking here.

Conclusion: you are your own therapist

Physiotherapy is a science of movement. And like any science, it is based on evidence. The data are clear: the patient who invests in their physical activity programme between sessions, who understands the purpose of their exercises and takes ownership of their recovery, heals better, faster, and with fewer recurrences.

The physiotherapist is a guide, an expert, a safeguard. But the engine of active rehabilitation is yourself. Every movement you make is an investment in your own health. Every exercise completed between sessions is one more step towards your independence.

So let us move. Not to please our practitioner. But for ourselves, for our quality of life, to regain what pain or injury has temporarily taken away. Because we are capable of it, and science proves it.
