Biofeedback may sharpen knee awareness after old injuries
NCT ID NCT07691528
First seen Jul 09, 2026 · Last updated Jul 10, 2026 · Updated 1 time
Summary
This pilot study tests whether a 3-week knee exercise program with visual and audio feedback can improve joint awareness (proprioception) and movement quality in adults aged 18–64 who had a knee injury at least a year ago. Participants complete both a supervised lab-based biofeedback program and an independent home program, separated by a rest period, to compare which approach works better. The study also checks if the training reduces fear of movement and whether simple tools can reliably measure joint position.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- biofeedback training program
- What this could lead to
- If effective, this approach could offer a simple, non-drug way to improve knee control and reduce fear of movement after injury.
- What could go wrong
- This is a very small pilot study with only 14 participants, so results may not apply broadly. The training is short (3 weeks) and effects may not last.
