Clinical Trial 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.

Description:

This randomized clinical trial will assess the efficacy of using physical activity behavior change intervention for Veterans recovering from total knee arthroplasty. Testing will occur at baseline (before surgery), at intervention midpoint (8 weeks after surgery), end of intervention (14 weeks after surgery), and 24 weeks after intervention. The primary outcome is accelerometer-assessed daily step count. Secondary outcomes include the percent time engaged in standing and walking activity and physical function (Six-Minute Walk, 30-Second Chair-Stand Test, Timed Up-and-Go, Western Ontario and McMaster Universities Osteoarthritis Index, and the Veterans RAND 12-Item Health Survey.

Related Conditions & MeSH terms

• Osteoarthritis
• Total Knee Arthroplasty

Intervention

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Free-living daily step count	Accelerometer-based measurement of free-living daily step count	Change from pre-surgery to end of intervention (14 weeks)
Secondary	30-Second Chair-Stand Test	Physical function test that assesses the number of sit-stand-sit transitions that a participant performs in the span of 30 seconds.	Change from pre-surgery to end of intervention (14 weeks), persisting at 24 weeks after intervention
Secondary	Six-Minute Walk Test	Physical function test measuring the total distance walked in a span of six minutes.	Change from pre-surgery to end of intervention (14 weeks), persisting at 24 weeks after intervention
Secondary	Timed Up-and-Go Test	A physical performance measure that includes rising from a chair, walking 3 meters, turning 180 degrees, returning to chair, and sitting.	Change from pre-surgery to end of intervention (14 weeks), persisting at 24 weeks after intervention
Secondary	Western Ontario and McMaster Universities Osteoarthritis Index	Self-report health status measure of pain, stiffness, and function for people with osteoarthritis of the hip or knee.	Change from pre-surgery to end of intervention (14 weeks), persisting at 24 weeks after intervention
