A twelve-week home-based exercise strategy will be offered to patients after their discharge from the hospital. This home-based exercise strategy will be delivered by means of videos on a tablet-pc and consist of specified exercise instructions for improving muscle strength, balance and functional movements.

The intervention group will be compared with existing patientdata who received usual care in the Netherlands

The duration of the program is 12 weeks. Patients start the program within 7 days after of the surgery. Patients perform exercises independently at home using the tablet PC for instructions. The program includes strengthening and walking exercises based on increasing the muscle force, balance, and functionality. The exercises comprise movements that train abductors, flexors, and extensors of the affected hip. The content of the program is based on previous research and on guidelines from the American Association of Orthopaedic Surgeons. For the rest, the program is designed in line with the most recent guidelines from the Royal Dutch Society for Physical Therapy. Patients are asked to exercise at least 5 days a week, with rest days on Thursday and Sunday. Strengthening exercises will be performed 3 times a week. The instructions for the exercises will be provided by videos on the tablet PC, which patients have to imitate.

Adherence to the rehabilitation program will be evaluated on the basis of the completion of the planned exercises.

Patient experience will be done in week 4 (T1) with a questionnaire adapted from the sensing and action to support mobility in ambient assisted living subject evaluation form [12,13]. The questionnaire contains questions about the user experience, the perceived intensity of the intervention, coaching, wearing of the sensor, and acceptability of the technology.

Patient experience will be done at week 12 at the end of the program (T2) with a questionnaire adapted from the sensing and action to support mobility in ambient assisted living subject evaluation form [12,13]. The questionnaire contains questions about the user experience, the perceived intensity of the intervention, coaching, wearing of the sensor, and acceptability of the technology.

To assess mobility objectively, the Timed Up & Go test (TUG) will be performed. The TUG is an accepted test to measure mobility. During the TUG, participants will be instructed to stand up from the chair, walk three meters, turn around, walk back and sit down on the chair again. Participants will be asked to walk at a fast but safe pace. The test will be performed three times. The TUG is considered reliable and practical. Measurements will be taken preoperatively (T0) and postoperatively at 4 weeks (T1), 12 weeks (T2) and 6 months (T3).
