Dry needling may unlock stiff muscles after stroke
NCT ID NCT04535479
First seen Jul 08, 2026 · Last updated Jul 09, 2026 · Updated 1 time
Summary
This study explores whether dry needling — a technique where thin needles are inserted into tight muscles to trigger a twitch — can reduce spasticity (stiffness) in people who have had a stroke. Researchers will measure changes in nerve pathways and movement over two visits. The goal is to see if this simple procedure can improve arm and leg function.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Dry needling
- What this could lead to
- If it works, dry needling could become a simple, drug-free way to ease muscle stiffness and improve arm or leg movement after a stroke.
- What could go wrong
- This is a small, early-stage study with only 32 participants, so results may not apply to everyone. Dry needling may cause temporary soreness or bruising.

Inclusion Criteria: For adults with no known neurological conditions: * ≥18 years old * no known neurological injuries. For individuals after stroke: * neurologically stable for \>6 months (and \>1 yr post stroke) * medical clearance to participate * unilateral ankle and/or wrist spasticity, confirmed by Modified Ashworth Scale (MAS) \> 1 and the presence of spastic hyperreflexia Exclusion Criteria: * motoneuron injury (i.e. the neurons that give rise to the axons innervating the muscles) with inadequate response to stimulation * a cardiac condition ( history of myocardial infarction, congestive heart failure, pacemaker use, coronary artery disease, atrial fibrillation, congenital heart disease, uncontrolled hypertension) * a medically unstable condition (including temporary infections and pregnancy) * age \<18 years old * cognitive impairment sufficient to interfere with informed consent or successful completion of the protocol * metal allergies * needle phobias * lymphedema over a limb (due to risk of infection/cellulitis) * abnormal bleeding tendencies * compromised immune system * vascular disease * uncontrolled diabetes * history of epilepsy (as DDN generates strong somatosensory sensation) * anxiety disorders or in distress.
