activity coach in TKA following a homebased exercise program

Patients in which the expectancy is that they could rapidly recover after a Total Knee Arthroplasty should not always go to the physical therapist. This group of patients could benefit from a homebased exercise program. The effect of exercise training depends on adherence to the activity instructions. The activity coach is an app on a smartphone. Patients wear the smartphone the whole day with them. The activity coach measures the activity level of the patient and gives feedback on it to the patient. The hypothesis is that if patients receive an activity coach alongside a home based exercise program, they are more active in Activities of Daily Living. This results in better physical functioning and better recovery after a TKA

Control group: homebased exercise program of 2 weeks (mobility, muscle force) instructed by specialised physical therapists.

Intervention group: homebased exercise program of 2 weeks (mobility, muscle force) instructed by specialised physical therapists and use of the activity coach.

The activity coach is developed by the Roessingh Research & Development (RRD) and is researched on other patient populations, such as COPD and Total Hip Arthroplasty. It gives the patient feedback about his activity level and doing exercises.
