Robot knee brace shows promise for crouch gait in cerebral palsy
NCT ID NCT06887764
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This pilot study tested a powered knee orthosis called Agilik in 10 people with cerebral palsy who have crouch gait. Participants walked with the device and without it to see if it improved their walking distance, speed, and knee motion. The goal was to find out if the device can help reduce crouching and make walking easier.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Powered knee orthosis (Agilik device)
- What this could lead to
- If it works, this device could help people with cerebral palsy walk more easily and with less effort.
- What could go wrong
- This was a very small pilot study with only 10 people, so results may not apply to everyone. The device is still new and needs much more testing.
