Botox for stiff legs: could it throw you off balance?

NCT ID NCT07108920

First seen Jun 25, 2026 · Last updated Jun 26, 2026 · Updated 2 times

Summary

This study looks at whether Botox injections in the thigh muscle (to treat stiff knee gait) affect a person's balance and risk of falling. Stiff knee gait can happen after a stroke, brain injury, or multiple sclerosis. The researchers will test balance before and after the injection using simple walking and standing tests. Only 15 people will take part, so the results will be very preliminary.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
Botulinum toxin (Botox)
What this could lead to
If this study finds no increased fall risk, it could reassure patients and doctors that Botox injections for stiff knee gait are safe regarding balance.
What could go wrong
This is a very small observational study (15 people) with no control group, so results may not apply to everyone. It only looks at short-term balance changes, not long-term safety.
