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.

Conditions

Interventions

BEHAVIORAL

Physical Activity Behavior Intervention

Home-based weekly sessions (30 min) using behavior change methods for promoting physical activity. Sessions will occur using home-based computer tablets for real-time video interface between the participant and researcher. Participants will wear wrist-mounted activity sensors with direct physical activity feedback during the intervention period to allow for behavioral feedback and action planning.

OTHER

Attention Control

Conventional rehabilitation with supplemental 10 telerehabilitation sessions that match the frequency and duration of the experimental arm. Attention control intervention provided as 10 telerehabilitation sessions of non-physical activity related education-only sessions.
