What this trial studies

This study aims to evaluate the effectiveness of three different non-invasive brain stimulation protocols combined with occupational therapy for stroke survivors experiencing upper extremity hemiplegia. Participants will be randomly assigned to receive either conventional tDCS, unconventional tDCS, or sham tDCS alongside contralaterally controlled functional electrical stimulation (CCFES) during a 12-week treatment period. The study will include a 6-month follow-up to assess recovery outcomes. All participants, therapists, and assessors will be blinded to the treatment received to ensure unbiased results.

Who should consider this trial

Good fit: Ideal candidates are adults aged 21 to 90 who have experienced a stroke 6 to 24 months prior and have specific functional capabilities.

Not a fit: Patients with severe cognitive impairments or those unable to follow commands may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly enhance recovery of hand movement in stroke survivors, improving their quality of life.

How similar studies have performed: This study represents a novel approach, as it is the first randomized clinical trial combining tDCS with CCFES for this purpose.
