Clinical Trial Summary

In this work, a novel hybrid ankle-foot robot is designed for gait rehabilitation after stroke, i.e., exoneuromusculoskeleton with balance sensing feedback (ENMS-BSF) by integrating the advantages of soft pneumatic muscle, functional electrical stimulation, exoskeleton and foot balance feedback in one system. With the assistance of the ENMS-BSF the foot drop and foot inversion could be corrected with improved muscle coordination in the paretic lower limb. The device is wearable and light-in-weight for unilateral application during walking. It is hypothesized that with the intervention of the ENMS-BSF the gait pattern of persons after stroke can be improved with long-term rehabilitative effects.

Eligibility

Inclusion Criteria:

• At least 6 months after the onset of stroke
• Have sufficient cognition to follow simple instructions, as well as understand the content and purpose of the experiment (Mini-Mental State Examination (MMSE) score >21).
• Have mild-to-moderate motor impairment in the affected lower limb with foot drop but be capable of standing and walking without manual assistance.

• Cerebrovascular Stroke
• Foot Drop
• Peroneal Neuropathies
• Stroke

Intervention

Device:
• ENMS-BSF assisted gait training
ENMS-BSF will correct the foot-drop and foot inversion during post-stroke walking. Each participant will receive 20 sessions device assisted training, with an intensity of 3-5 sessions/week, 1 hr/session. In each session, a participant will complete the device-assisted walking on flat ground with a natural speed and with the aid of a four-pronged cane.
