Mobile app to help recovery after hip, knee, or spine surgery

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a prospective, single-arm pilot enrolling older adults recovering from hip fracture fixation, spinal fusion, or total hip/knee arthroplasty at Yale New Haven Hospital Saint Raphael's Campus. Participants who are cognitively able and own a mobile phone will use an app that sets reminders and adjusts in-bed exercise difficulty based on patient feedback. The study will track app usage, patient satisfaction, and physical therapy outcomes and will collect therapist feedback. Initial enrollment is 15 patients with a planned expansion to a randomized controlled trial of 50 participants per arm if pilot results support it.
