Geriatrics Rehabilitation

The goal of this clinical trial is to learn if a 12-week digitally supported, multimodal home rehabilitation program using the medical application Akina is as effective compared to routine care regarding functional independence in older adults undergoing hip surgery. How is this multimodal home rehabilitation program received by patients? Is this multimodal home program at least as effective in terms of functional indpendence, muscle status, mobility and quality of life compared to routine care? Researchers will compare the multimodal rehabilitation program using the application Akina to routine care to see if the program works to treat patients after hip surgery. Participants will: Undergo the rehab program at home or receive routine care (outpatient physiotherapy) for 12 weeks Visit the clinic after 6 and 12 weeks
