The adherence gap: why home exercise programs fall short, and what actually helps
Every clinician knows the moment. A patient returns for review, and it becomes clear the home program hasn't really happened. The exercises were done a few times in the first week, then life took over.
It's not an isolated experience. In people with chronic conditions, poor adherence to exercise therapy often exceeds 50%, and home programs are where the problem is sharpest (Ricke et al., Frontiers in Sports and Active Living, 2023).
Who is most likely to follow through?
The same 2023 systematic review and meta analysis looked at which factors predict adherence to home exercise. The strongest signals were:
Exercise history: people who were already active were about four times more likely to adhere (OR 4.05).
Self efficacy: confidence in being able to do the exercises (OR 1.58).
Motivation and perceived control over the program (OR 1.25 and 1.21).
Fewer comorbidities, less fatigue and less depression were also linked to better adherence.
The practical message: adherence isn't just willpower. It is shaped by confidence, health and circumstance, many of which clinicians can influence.
What the evidence says helps
A systematic review of 12 randomised trials in physiotherapy found four interventions with promise for improving adherence to prescribed exercise (Peek et al., Physiotherapy, 2016):
An activity monitor with a feedback system
Clear written exercise instructions
A behavioural exercise program with booster sessions
Goal setting
The authors were careful to say the evidence is not yet strong enough to mandate any single approach. An earlier review reached a similar conclusion: adherence is multidimensional, so strategies need to be "broad in spectrum" rather than a single fix (McLean et al., Manual Therapy, 2010).
Putting it into practice
Build confidence early. Walk through each exercise in the clinic and check the patient can do it independently before they leave.
Make instructions unmistakable. Clear visuals, simple language and a defined number of sets and reps beat a photocopied sheet.
Set goals together. Link the program to something that matters to the patient, like walking to the shops or getting back to golf.
Close the feedback loop. Patients do more when they know someone is seeing their progress, and clinicians can act sooner when they can see it too.
Plan the boosters. A short call or message at the point motivation typically drops can reset momentum.
The role of technology
Feedback and monitoring are where digital tools can help most. BIBO is designed to guide patients through each session at home, with corrections as they move, and to show clinicians which sessions were completed, so follow up is based on data rather than recall. Technology won't replace the therapeutic relationship, but it can make sure the program keeps going between appointments.
