What this trial studies

This project aims to evaluate the immediate and long-term effects of combining botulinum toxin type A (BoNT-A) injections with robotic-assisted gait training in patients experiencing stiff-knee gait following a stroke. The study focuses on patients who have had an ischemic or hemorrhagic stroke for at least three months and assesses the effectiveness of this combined approach in enhancing walking ability and reducing spasticity. By comparing outcomes between those receiving both treatments and those receiving only one, the trial seeks to refine rehabilitation strategies for post-stroke patients. The goal is to improve mobility and reduce the risk of falls and other complications associated with stiff-knee gait.

Who should consider this trial

Good fit: Ideal candidates are adults aged 20 and older who have experienced a stroke at least three months prior and exhibit spasticity in the rectus femoris muscle.

Not a fit: Patients who are pregnant, have severe cardiovascular issues, or have undergone previous surgical interventions on the affected leg may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly enhance walking ability and quality of life for stroke survivors with spastic gait.

How similar studies have performed: Other studies have shown promising results with robotic-assisted therapies in rehabilitation, suggesting potential success for this combined approach.
