Summary

A novel interactive exoskeleton robotic system with embedded force and motion sensors will be developed to facilitate walking of stroke patients with hemiparesis. The robot will synchronise with the gait pattern of the stroke patient to provide assistance in ankle dorsiflexion during swing phase. It is hypothesised that the robot can facilitate stable and longer walking distance for stroke patients with drop foot problem. It can be applied on unilateral side, which is suitable for stroke patients with hemiparesis. The whole system design is lightweight, compact, comfortable, and user-friendly in hospital or at home settings.

Conditions

Interventions

DEVICE

Ankle Robot with Power Assistance

Stroke patients will enrol in a 20-session gait training program for at least two sessions per week. In each session, the stroke patient will walk overground continuously for 2 \* 10 minutes and walk up/down a staircase (about 10 steps per flight) for 10 minutes, rest will be provided in between each round of walking or stair climbing. This training can promote gait recovery and physical fitness. They will wear the Ankle Robot during the gait training. The motor will synchronise with the paretic-side gait pattern to provide dorsiflexion moment during swing phase, and free the ankle joint when the sole is loaded.

DEVICE

Sham

Stroke patients will enrol in a 20-session gait training program for at least two sessions per week. In each session, the stroke patient will walk overground continuously for 2 \* 10 minutes and walk up/down a staircase (about 10 steps per flight) for 10 minutes, rest will be provided in between each round of walking or stair climbing. This training can promote physical fitness. They will wear the Ankle Robot during the gait training. The robot will synchronise with the paretic-side gait pattern to the Ankle Robot provides very low assistance which can be barely perceived by the stroke patient but does not suffice to support the ankle dorsiflexion.
