Optimizing a Remote-based Physical Activity Intervention for Adults with Total Knee Replacement
The purpose of this study is to identify which supplemental intervention components added to an online exercise program contribute to the greatest increases in physical activity (total MVPA and percent meeting guidelines \[≥150 min/week of MVPA\]) in adults with knee replacement at 6 and 12 months. Secondary outcomes will examine changes in pain and physical function.
• had a knee replacement (including primary, staged or independent bilateral, or revision) at least 12 months ago
• have a computer, tablet, or smartphone with active internet access
• self-report engaging in less than 60 minutes/week of moderate-intensity physical activity
• be English-speaking and able to read consent and study materials written in English
• be willing to complete the 4 remote assessments, including physical activity monitoring
• be willing to be randomized to receive 0-4 supplemental intervention components.
