Cervical tsDCS for improving hand and arm function after stroke

Official title: Clinical and Neurophysiological Evaluation of the Effects of Cervical tsDCS on Stroke Patients With Distal Upper Limb Strength Deficit

Run by IRCCS San Raffaele Roma · NCT06826274 · Data updated 2026-11-12

This study tests whether cervical transcutaneous direct current stimulation (tsDCS) can help people who have weakness or poor dexterity in the arm after a stroke to gain strength and perform daily tasks better.

Is this trial a fit for you?

Likely a good fit

Adults over 18 with a recent unilateral stroke (within 30 days) and mild-to-moderate arm weakness who can consent and understand instructions.

Probably not a fit

Patients with severe spasticity, aphasia, neglect, disabling neurological history, epilepsy, significant comorbidities, or contraindications to tsDCS may not benefit.

What this trial studies

This interventional study investigates the facilitatory effects of cervical tsDCS on upper-limb motor responses in adults who recently had a stroke. Participants with mild-to-moderate arm weakness will receive tsDCS in addition to usual care to see if it improves strength, dexterity, and daily-living function. The trial includes an ischemic or hemorrhagic stroke window of up to 30 days post-onset and compares outcomes in adults with residual upper-limb function. A healthy control group will be enrolled to help interpret physiological responses. Safety and tolerability of tsDCS will also be monitored.

Why it matters

Potential benefit: If successful, participants may experience improved arm strength, better hand dexterity, and easier performance of daily activities.

How similar studies have gone: Prior research suggests that noninvasive brain stimulation approaches can modulate motor function after stroke, but results vary and this specific cervical tsDCS approach is relatively novel.
