Remote exercise program for people with knee replacements
Optimizing a Remote-based Physical Activity Intervention for Adults with Total Knee Replacement
Different online program features will be tried to help adults who had a total knee replacement become more active.

What this research studies
You would join a 6-month, fully automated online program called Energize! that helps you plan and report daily exercise, watch brief behavioral videos, and get automated feedback. The study enrolls adults at least 12 months after total knee replacement and uses activity trackers (accelerometers) to measure movement. Using the Multiphase Optimization Strategy (MOST), participants are randomized to receive different additional program components so researchers can find the most effective, scalable combination. Participation is remote and nationwide, so you can take part from home if you have internet access and can wear the activity tracker.
Who could benefit from this research
Good fit: Adults at least 12 months after total knee replacement who can use the internet and wear an activity tracker are ideal candidates.
Not a fit: People less than 12 months after surgery, those without reliable internet or mailing addresses, or those who cannot safely increase activity due to other medical conditions may not benefit.
Why it matters
Potential benefit: If successful, this could provide an affordable, home-based way for people with knee replacements to increase daily activity and improve long-term health.
How similar studies have performed: Automated online physical-activity programs have shown benefits in other older-adult groups, but they have rarely been tested specifically after total knee replacement.
