Summary

This trial compares two techniques for guiding botulinum toxin injections to treat leg spasticity after a stroke: ultrasound and electrostimulation. The goal is to see which method improves ankle flexibility and reduces pain during the procedure. Adults with stroke-related spasticity in the calf muscles are eligible to participate.

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 injection guided by either ultrasound or electrostimulation
What this could lead to: If ultrasound proves superior, it could become the preferred method for guiding botulinum toxin injections, improving accuracy and reducing pain for stroke survivors with spasticity.
What could go wrong: This is a small, early-stage trial, and the results may not be conclusive. Ultrasound guidance might not show a clear advantage over the existing technique, and individual responses can vary.
