NCT ID NCT05488054
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study is testing a wearable sensor that measures muscle oxygen levels in high school and college athletes recovering from ACL or hip surgery. The goal is to see if the sensor can give doctors and trainers better data to decide when an athlete is ready to return to sports. About 226 participants aged 14 to 30 will wear the sensor during rehab, and the study compares the injured leg to the healthy one.
