Optimizing Physical Activity Outcomes for Veterans After Total Knee Arthroplasty
In Brief
A clinical study evaluating Physical Activity Behavior Intervention and Attention Control for Total Knee Arthroplasty and Osteoarthritis. Completed, enrolled 114 participants across 1 site.
Detailed 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.
Study Details
Timeline
Interventions
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.
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.
