Could shock waves boost botox for Stroke-Related foot stiffness?
NCT ID NCT07758322
First seen Aug 11, 2026 · Last updated Aug 12, 2026 · Updated 1 time
Summary
This trial investigates whether adding focused shock wave therapy to standard Botox injections can better ease foot stiffness and improve walking in people with post-stroke spastic equinovarus foot. Participants are randomly assigned to receive Botox alone, shock waves just before Botox, or shock waves two weeks after. The study measures changes in spasticity, ankle movement, muscle strength, and walking ability over a year to see if the timing of shock wave therapy makes a difference.
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 type A (Botox) combined with focused extracorporeal shock wave therapy
- What this could lead to
- If adding shock wave therapy improves outcomes, it could establish a better standard of care for post-stroke foot spasticity, enhancing mobility and quality of life.
- What could go wrong
- This is a small, early-stage trial, and the optimal timing of shock wave therapy remains uncertain. Results may not generalize, and individual responses to Botox and shock waves can vary.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Adults aged 18 to 87 years. * Clinical diagnosis of chronic stroke. * Presence of unilateral spastic equinovarus foot. * Lower-limb spasticity requiring treatment with botulinum toxin type A. * Ability to understand the study procedures and provide written informed consent. Exclusion Criteria: * Botulinum toxin type A injection in the affected lower limb within the previous 12 weeks. * Previous extracorporeal shock wave therapy in the affected lower limb within the previous 12 weeks. * Fixed ankle contracture preventing passive correction. * Other neurological or musculoskeletal disorders affecting gait assessment. * Pregnancy or breastfeeding. * Contraindications to botulinum toxin type A or extracorporeal shock wave therapy. * Severe cognitive impairment preventing participation or informed consent. * Participation in another interventional clinical trial.
