Improving online exercise for adults after knee replacement
Optimizing a Remote-based Physical Activity Intervention for Adults With Total Knee Replacement
NA · University of South Carolina · NCT06768762
This study is testing whether adding extra support like phone coaching and personalized feedback can help adults who had knee replacement surgery stick to an online exercise program and improve their activity levels.

What this trial studies
This study aims to determine which additional components enhance an online exercise program designed for adults who have undergone knee replacement surgery. Participants will engage in a 6-month automated online program that gradually increases their physical activity levels, starting from 75 minutes per week to 200 minutes per week. They will also receive weekly video lessons and activities to reinforce behavioral principles for maintaining physical activity. Additionally, participants will be randomly assigned to receive up to four supplemental interventions, such as phone coaching and individualized feedback, to assess their impact on physical activity levels and overall function.
Who should consider this trial
Good fit: Ideal candidates are adults who have had a knee replacement at least 12 months ago and currently engage in less than 60 minutes of moderate-intensity physical activity per week.
Not a fit: Patients with contraindications to physical activity or those currently undergoing physical therapy for knee issues may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could significantly improve physical activity levels and quality of life for patients recovering from knee replacement surgery.
How similar studies have performed: Previous studies have shown success with online exercise interventions for similar populations, indicating a promising approach.
