A Low-Cost Biofeedback System for Electromyogram-Triggered Functional Electrical Stimulation Therapy: An Indo-German Feasibility Study
Figure 7
Ensemble averaged linear envelope of EMG (mean EMG), normalized (norm) by the maximum voluntary contraction from tibialis anterior (TA) and medial gastrocnemius (GM) muscles over 250 gait cycles during treadmill walking (1 m/s) for able-body (able) and stroke (stroke) subjects. Colors denote 6 stroke subjects and the markers denote 4 able-body subjects. (a) Baseline flexor-extensor (TA-GM) Cyclograms, (b) postintervention flexor-extensor (TA-GM) Cyclograms, and (c) 2-day postintervention flexor-extensor (TA-GM) Cyclograms. [22].
