What this trial studies

This study aims to reduce a common movement impairment known as 'flexion synergy' that occurs after a stroke, making it difficult for patients to reach outward with their arm. Eighty-six individuals with severe hemiparetic stroke will be recruited upon admission to the Shirley Ryan AbilityLab for rehabilitation. Participants will receive either experimental or comparison therapy in addition to standard rehabilitation treatments and will be monitored for one year to assess their progress. Evaluations will occur weekly during therapy and bi-monthly after discharge.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 85 who have experienced a severe hemiparetic stroke within the last 90 days.

Not a fit: Patients with pre-existing disabilities or chronic neurological conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this therapy could significantly improve arm mobility and overall rehabilitation outcomes for stroke patients.

How similar studies have performed: Other studies have shown promise in using targeted rehabilitation approaches for stroke recovery, suggesting potential for success in this novel intervention.
