Arms of the Study
Arm 1
Experimental
FES in patients with hemiplegia
Patients will be equipped with 5 inertial measurement units. Two wireless bluetooth pressure insoles will be connected to the Raspberry. Electrical stimulation will be delivered via a wireless stimulator to the quadriceps and hamstrings via surface electrodes. Insoles will be used to online analyze Paretic Foot Support to discriminate between stance and swing phases. Stimulation will also be delivered just before initial contact at the end of swing phase. In stance phase, stimulation will be triggered either to quadriceps or hamstrings, depending on the paretic knee angle estimation relatively to the knee angle setpoint defined by the practitioner as the optimal flexion during stance phase (around 5°).
