Improving touch perception in one hand by stimulating the other hand

Stimulate One Hand to Improve Tactile Perception on the Other

Not applicable Interventional Hospices Civils de Lyon · NCT06149325

This study is testing if stimulating one hand can help improve touch sensitivity in the other hand for people aged 30-80 who have had a stroke.

What this trial studies

This study aims to compare the effects of repetitive somatosensory stimulation (RSS) on one hand with sham stimulation to assess improvements in tactile acuity in the opposite hand of patients who have experienced a stroke. Participants will be individuals aged 30-80 with unilateral stroke and varying degrees of sensory loss in the hand opposite to the stroke. The study will evaluate whether RSS can temporarily enhance tactile perception in the affected hand, potentially leading to better rehabilitation outcomes. The intervention will be conducted in a controlled environment to ensure accurate results.

Who should consider this trial

Good fit: Ideal candidates are adults aged 30-80 who have experienced a unilateral stroke at least three months prior and have sensory loss in the hand opposite to the stroke.

Not a fit: Patients with sensory impairments due to conditions like diabetes or those with severe cognitive impairments or multiple strokes may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly enhance tactile perception in stroke patients, improving their quality of life and rehabilitation prospects.

How similar studies have performed: While the approach of using RSS for sensory improvement is promising, it is relatively novel and has not been extensively tested in similar studies.
