Optimizing a Remote-based Physical Activity Intervention for Adults With Total Knee Replacement
University of South Carolina
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.
Description
All participants will receive a 6-month, fully automated online behavioral exercise program (Energize! Exercise Program). This program is designed to increase moderate-intensity physical activity among individuals who engage in little to no physical activity at baseline. Over the course of the program, participants are given a physical activity goal which starts at 75 minutes per week and gradually progresses to 200 minutes per week. Participants are instructed to view a 10-15-minute video lesson weekly, during months 1-3, and monthly during months 4-6. These lessons teach behavioral principle…

Interventions
- BehavioralPhone Coaching
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.
- BehavioralProgress reports to providers
Progress reports on physical activity and program adherence will be sent to participants providers at 3 and 6 months.
- Behavioral'Hear from Others' Videos
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.
- BehavioralIndividualized Feedback
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.
