Efficacy of Focused Shock Wave Therapy Before and After Botulinum Toxin Injection in Patients With Post-Stroke Spastic Equinus/Equinovarus Foot: A Randomized Clinical Trial
Spain69 participantsStarted 2024-10-10
Plain-language summary
Spastic equinovarus foot is the most common lower limb motor impairment after stroke and has a significant impact on gait, mobility, and quality of life. Botulinum toxin type A (BoNT-A) is considered the first-line treatment for focal post-stroke spasticity. Extracorporeal shock wave therapy (ESWT) has shown promising results as an adjunctive treatment; however, the optimal timing for its administration in combination with BoNT-A remains unknown.
This prospective, randomized, evaluator-blinded clinical trial aims to determine whether focal ESWT administered before or after BoNT-A injection is more effective than BoNT-A alone in patients with chronic post-stroke spastic equinovarus foot. Sixty-nine participants will be randomly allocated to one of three treatment groups: (1) BoNT-A alone; (2) one session of focal ESWT immediately before BoNT-A injection; or (3) one session of focal ESWT two weeks after BoNT-A injection. The primary outcome is spasticity measured with the Modified Ashworth Scale (MAS). Secondary outcomes include the Modified Tardieu Scale, passive ankle range of motion, muscle strength (MRC), 10-Meter Walk Test (10MWT), Functional Ambulation Classification (FAC), pain (VAS), Patient-Specific Assessment Scale (PSAS), muscle echogenicity using the Heckmatt scale, and muscle stiffness assessed by real-time elastography. Assessments will be performed at baseline and during follow-up through week 54.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
