Nerve zap plus robot arm may boost stroke recovery
NCT ID NCT07257107
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether combining a gentle nerve stimulation (taVNS) with robot-assisted arm training helps stroke survivors regain arm function better than robot training alone. Thirty adults who had a stroke at least 6 months ago and have moderate to severe arm weakness will participate. The goal is to see if this combo improves movement, strength, and daily life skills over 5 weeks.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * 1\) Individuals aged 18-70 years diagnosed with ischemic or hemorrhagic stroke lasting longer than 6 months, * Moderate to severe upper extremity weakness (20-50 out of 66 on the Fugl-Meyer Upper Extremity Motor Assessment Scale), * Ability to communicate and understand (Mini Mental State Examination (MMSE) score ≥ 23), and 4) Upper extremity spasticity of 2 or less on the Modified Ashworth Scale. Exclusion Criteria: * Use of any stimulation device, such as a pacemaker or other neurostimulator, * Presence of a medical or cognitive condition (personality disorder, anxiety, depression, etc.) that would prevent participants from participating in the study, * Receiving a Botox injection into the affected upper extremity at least 4 weeks prior, * Severe spasticity in the upper extremity (Modified Ashworth Scale ≥3), * Presence of dysphagia or aphasia, * Presence of cardiac problems such as atrial fibrillation, atrial flutter, sick sinus syndrome, or atrioventricular block.
