Robot helper gets knee patients moving faster at home
NCT ID NCT07539948
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a new robot device that helps people with knee osteoarthritis do rehab exercises at home after surgery. Ten adults used the device for one month to see if it improved their leg strength and knee function. The goal was to make recovery easier and faster, especially during the weeks when patients usually exercise alone.
