Is this trial a fit for you?

Likely a good fit

Adults aged 18 to 70 with recent unilateral stroke (ischemic or hemorrhagic) and balance impairment (BBS 21-44) within 6 months of onset.

Probably not a fit

Patients with unstable vital signs, significant cognitive impairment, or implanted cardiac devices may not benefit and could be excluded for safety.

What this trial studies

In this randomized trial, participants with recent ischemic or hemorrhagic stroke and balance impairment will receive taVNS combined with balance training or balance training alone. The study aims to see if taVNS can enhance postural control and modulate autonomic responses such as heart rate variability and blood pressure variability. Rehabilitation will focus on practical balance tasks, with outcomes including standardized balance scores and autonomic measurements. The trial uses non-invasive stimulation delivered through ear electrodes, paired with a structured therapy program. Safety monitoring and standardized assessments will be conducted to compare the two groups.

Why it matters

Potential benefit: If successful, taVNS with balance training could improve balance and stability, potentially reducing fall risk in stroke survivors.

How similar studies have gone: Prior neuromodulation approaches show potential in supporting motor and autonomic recovery after stroke, but this exact taVNS plus balance training approach is novel.
