Fig. 3From: Partial weight support of the arm affects corticomotor selectivity of biceps brachiiBaseline EMG activity at low (0Â %), medium (45Â %), and high (90Â %) levels of WS is plotted for a: anterior deltoid, b: biceps brachii, and c: pronator teres. Each data point represents rmsEMG from a single trial normalized to maximum voluntary contractionBack to article page
