Shock therapy for wobbly ankles? new combo shows promise
NCT ID NCT06204861
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether adding a special electric therapy (CRET) to balance exercises helps people with chronic ankle instability recover faster. 31 adults with weak, unstable ankles were split into three groups: balance training alone, electric therapy alone, or both together. Researchers measured ankle function, balance, and stability to see which approach worked best.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Capacitive and Resistive Electric Transfer (CRET) therapy
- What this could lead to
- If it works, this could offer a faster, more effective rehabilitation option for people with chronic ankle instability.
- What could go wrong
- This is a small, completed study with only 31 participants. Results may not apply to everyone, and the therapy is not a cure—it aims to ease symptoms and improve function.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Age ≥18 years; * At least 12 months between the initial sprain and the current experiment, the sprain occurred with symptoms of inflammatory reactions such as pain and swelling, resulting in the inability to engage in physical activity for at least 1 day, and the most recent ankle sprain was more than 3 months away from the experiment; * The occurrence of a re-sprain or "sensory instability" condition after the initial sprain, as follows: a. "sensory instability": at least 2 times within 6 months from the experiment; b. re-sprain: 2 times or 2 times of the same ankle sprain " condition as follows: a. "Sensory destabilization": at least 2 times within 6 months from the experiment; b. Re-sprain: 2 or more sprains of the same ankle; * Ankle Joint Functional Assessment Tool (AJFAT) score ≤ 26; * No complaint of instability in the other ankle; * No mechanical ankle instability, i.e., negative anterior drawer test and talar tilt test * No intervention by any means of rehabilitation before participation in this experiment. Exclusion Criteria: * The presence of lower extremity fracture on either side; * The presence of central or peripheral nervous system injury * The presence of lower extremity surgery on either side.
