Digital Home-Based Exercise Program With or Without Personal Coaching to Boost Physical Activity After Hip Replacement in Older Adults

What this Trial Is About

Researchers are evaluating the effectiveness of a 12-week digital home-based exercise program, with or without personal coaching, to increase physical activity in older adults after total hip arthroplasty THA. This study aims to find out if combining the digital exercise program with personal coaching leads to higher physical activity six months after surgery compared to usual care. It also compares the effects of the exercise program alone to usual care and to the combined program with coaching. Participants are randomly assigned after a six-week postoperative assessment to one of three groups a 12-week digital exercise program with virtual personal coaching, the same exercise program without coaching, or usual care without additional intervention. The exercise program uses the Keep-On-Keep-Up KOKU app, which guides strength and balance exercises to be done three times per week at home. Personal coaching involves three video call sessions to support physical activity through goal setting, planning, self-monitoring, and overcoming barriers. Participants also receive a wrist-worn activity tracker to help monitor their activity. Participants are assessed one week before surgery, six weeks after surgery, and six months after surgery. Assessments include wearing a body-fixed sensor to measure daily step count and walking distance, along with other mobility and health measures such as walking speed, hip pain, psychological factors, and physical capacity. Researchers also track falls, adherence to the interventions, quality of life, and healthcare use. The total participation time includes the 12-week intervention and follow-up up to six months post-surgery, with safety and outcome monitoring throughout.
