Brief 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.

Condition or disease Intervention/treatment Phase
Total Knee Arthroplasty Osteoarthritis Behavioral: Physical Activity Behavior Intervention Other: Attention Control Not Applicable

Detailed 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.

Arm Intervention/treatment
Experimental: Physical Activity Behavior Intervention
A 12-week behavior change intervention that supplements conventional rehabilitation including: 10 telerehabilitation sessions, daily activity sensor use, education, self-monitoring, tailored feedback, barrier/facilitator identification, promotion of problem solving, action planning, and encouragement.
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.

Active Comparator: Attention Control
Conventional rehabilitation with 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.
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.




Primary Outcome Measures :
  1. Free-living daily step count [ Time Frame: Change from pre-surgery to end of intervention (14 weeks) ]
    Accelerometer-based measurement of free-living daily step count


Secondary Outcome Measures :
  1. 30-Second Chair-Stand Test [ Time Frame: Change from pre-surgery to end of intervention (14 weeks), persisting at 24 weeks after intervention ]
    Physical function test that assesses the number of sit-stand-sit transitions that a participant performs in the span of 30 seconds.

  2. Six-Minute Walk Test [ Time Frame: Change from pre-surgery to end of intervention (14 weeks), persisting at 24 weeks after intervention ]
    Physical function test measuring the total distance walked in a span of six minutes.

  3. Timed Up-and-Go Test [ Time Frame: Change from pre-surgery to end of intervention (14 weeks), persisting at 24 weeks after intervention ]
    A physical performance measure that includes rising from a chair, walking 3 meters, turning 180 degrees, returning to chair, and sitting.

  4. Western Ontario and McMaster Universities Osteoarthritis Index [ Time Frame: Change from pre-surgery to end of intervention (14 weeks), persisting at 24 weeks after intervention ]
    Self-report health status measure of pain, stiffness, and function for people with osteoarthritis of the hip or knee.

  5. Veterans RAND 12-Item Health Survey [ Time Frame: Change from pre-surgery to end of intervention (14 weeks), persisting at 24 weeks after intervention ]
    A self-report assessment of health-related quality of life assessing the domains of physical functioning, role-physical, bodily pain, general health perceptions, vitality, social functioning, role-emotional, and mental health.
