The patient's perspective on rehabilitation with wireless accelerometers, activity tracking and motivational feedback following knee replacement: A qualitative study prior to a randomised controlled trial (KneeActivity).

This study applied a user-driven approach to customise health technology for postoperative rehabilitation in knee replacement patients. Initially, the technology had both technical and functional problems, but system revisions based on patient feedback improved its acceptance. The refined technology is undergoing testing in a randomised design.
