NCT ID NCT07606534
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether strengthening the ankle, the hip, or both together works best for people with chronic ankle instability. 45 participants aged 18-35 will do isometric exercises three times a week for four weeks. Researchers will measure improvements in stability, strength, and balance to find the most effective approach.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- isometric strengthening exercises (ankle, hip, or combined)
- What this could lead to
- If successful, this could help clinicians choose the most effective strengthening program to improve ankle stability and reduce the risk of future sprains in people with chronic ankle instability.
- What could go wrong
- This is a small, early-stage trial with only 45 participants, so results may not apply to everyone. The exercises are isometric and may not fully reflect real-world movement.
