Comparing Dry Needling and Botulinum Toxin for Post-Stroke Spasticity

Comparative Study of the Mechanism of Action of Dry Needling and Botulinum Toxin Type A as a Treatment for Lower Limb Post-stroke Spasticity: a Proof of Concept Controlled Trial

Phase2; Phase3 Interventional Universiteit Antwerpen · NCT06296082

This study is testing whether dry needling can help reduce muscle tightness in the legs of stroke survivors just as well as a common injection treatment.

What this trial studies

This clinical trial is a randomized parallel group study conducted in Spain, Canada, and Belgium, aimed at comparing the effectiveness of Botulinum Toxin type A (BTX-A) and Dry Needling (DN) in treating lower limb spasticity in patients who have experienced a first stroke within the last 12 months. Participants will be randomly assigned to receive either one session of BTX-A or 12 weekly sessions of DN. The study will assess the effects of these treatments on spasticity using blinded evaluators before, during, and after treatment, with a follow-up at four weeks. The primary hypothesis is that DN will have comparable effects to BTX-A in reducing spasticity by decreasing stretch reflex excitability.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-75 who have experienced their first stroke within the last 12 months and exhibit ankle plantar flexor spasticity.

Not a fit: Patients with medical conditions that interfere with data interpretation or those who have contraindications for BTX-A or DN treatment may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide an effective alternative treatment for post-stroke spasticity, improving mobility and quality of life for patients.

How similar studies have performed: Other studies have shown promising results with similar approaches, but this specific comparison of DN and BTX-A is relatively novel.
