What this trial studies

This study investigates the effects of transcutaneous electrical nerve stimulation (TENS) and transcutaneous vagus nerve stimulation (tVNS) on cognitive and upper limb motor function in individuals who have suffered a chronic stroke. Participants will be divided into three groups, receiving either TENS, tVNS, or a placebo treatment alongside upper limb exercises. The aim is to evaluate the effectiveness of these non-invasive interventions in enhancing both cognitive abilities and motor skills in stroke survivors. The study seeks to fill a gap in existing research regarding the impact of these treatments on cognitive function post-stroke.

Who should consider this trial

Good fit: Ideal candidates are individuals aged 50 to 80 who have experienced a single stroke at least one year prior and have some movement ability in their arms.

Not a fit: Patients with other neurological diseases or those with cardiac pacemakers or cochlear implants may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a new non-invasive treatment option to improve cognitive and motor functions in stroke patients.

How similar studies have performed: While similar approaches have been explored, this specific combination of TENS and tVNS for cognitive function in stroke patients is novel and has not been extensively tested.
