Optimizing a Remote-based Physical Activity Intervention for Adults with Total Knee Replacement
University of South Carolina
336 participants
Jan 21, 2025
INTERVENTIONAL
Summary
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.

- 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.
Exclusion Criteria10
- any contraindications to physical activity (e.g., chest pain)
- have a scheduled surgery within the next 12 months (e.g., hip or knee replacement)

Interventions
Participants will receive 11 coaching calls with a health coach. Calls will occur weekly during the first month, twice/month during months 2-3, and once/month during months 4-6. Each call is expected to last 10-15 minutes.
Progress reports on physical activity and program adherence will be sent to participants providers at 3 and 6 months.
Participants will receive monthly 'Hear From Others' videos. The videos will include other adults with knee replacement discussing the challenges they have faced and strategies to overcome barriers to activity.
Participants will receive individualized feedback from a coach via email. The feedback will specifically focus on participant responses to the 'Apply Your Knowledge' activities and will correspond with the video lessons. Feedback will be weekly during months 1-3 and monthly during months 4-6.
