Study Summary

Although total knee arthroplasty is an effective intervention for decreasing knee pain and improving physical function, physical activity levels remain low up to a year after surgery. This study will use mobile-health technology to deliver an intervention designed to improve physical activity behavior for Veterans recovering from total knee arthroplasty. The study will assess the effectiveness of using behavior-change intervention as a supplement to conventional rehabilitation to improve physical activity. The intervention will be delivered using home-based tablet computers for Veterans to have remote interaction with the researcher and real-time physical activity feedback from a wrist-worn activity sensor.

Primary Outcome

Accelerometer-based measurement of free-living daily step count
