Digital Home-Based Physical Activity Promotion for Older Adults After Total Hip Arthroplasty

The goal of this clinical trial is to evaluate the efficacy of a 12-week digital home-based intervention program, consisting of a tablet-based exercise program with or without personal coaching, to promote physical activity (PA) in older adults after total hip arthroplasty (THA). The main question it aims to answer is: • Does the combination of the digital exercise program and personal coaching lead to higher PA six months after THA compared to usual care among older adults? Secondary questions are: * Does the digital exercise program alone lead to higher PA compared to usual care? * Does the digital exercise program combined with personal coaching lead to higher PA compared to the exercise program alone? Participants' PA will be objectively measured with a body-fixed sensor at 1 week before THA (T1), 6 weeks after THA (T2), and 6 months (i.e. after THA (T3). After the postoperative assessment at T2, participants will be randomly assigned to one of three groups: * 12-week tablet-based exercise program at home with virtual personal coaching for physical activity promotion * 12-week tablet-based exercise program at home * Usual care (control group, no additional intervention)
