Electric knee sleeve aims to speed up ACL recovery in cadets
NCT ID NCT06341868
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests a wearable electrical stimulation sleeve called KneeStim in 60 military cadets recovering from ACL reconstruction. Half will use the device during rehab and daily tasks for 12 weeks, while the other half gets standard care with a low-intensity version. Researchers will measure changes in walking and running patterns, muscle mass, and how quickly cadets return to full duty.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- KneeStim device (wearable electrical stimulation knee sleeve)
- What this could lead to
- If it works, this could lead to faster and more complete recovery of walking and running after ACL surgery.
- What could go wrong
- This is a small, early-stage trial with only 60 participants, so results may not apply to the general public. The device may not improve outcomes beyond standard care.
