Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are stroke survivors at least six months post-event with mild to moderate motor impairment in the affected lower limb.
✕Probably not a fit
Patients with severe spasticity at the ankle joint or those receiving concurrent lower limb rehabilitation interventions may not benefit from this study.

What this trial studies
This study evaluates a novel hybrid ankle-foot robot designed to assist in gait rehabilitation for individuals recovering from stroke. The device, known as the exoneuromusculoskeleton with balance sensing feedback (ENMS-BSF), integrates soft pneumatic muscles, functional electrical stimulation, and exoskeleton technology to improve muscle coordination and correct foot drop and inversion. Participants will engage in gait training with this wearable device, which aims to enhance their walking patterns and provide long-term rehabilitative benefits. The study focuses on individuals who have experienced a stroke at least six months prior and have mild to moderate motor impairments.
Why it matters
Potential benefit: If successful, this intervention could significantly improve walking ability and quality of life for stroke survivors with foot drop.
How similar studies have gone: While the approach is innovative, similar robotic-assisted rehabilitation methods have shown promise in improving mobility in stroke patients, suggesting potential for success.
