The Effects of the Biceps Brachii and Brachioradialis on Elbow Flexor Muscle Strength and Spasticity in Stroke Patients

Figure 3

sEMG signals of the elbow flexor muscles (the biceps brachii and brachioradialis) during MVIC. (a) Mean RMS values of the biceps brachii and brachioradialis during MVIC on the paretic side. (b) Peak RMS values of the biceps brachii and brachioradialis during MVIC on the nonparetic side. (c) Mean RMS values of the biceps brachii during MVICon the paretic and nonparetic sides. (d) Mean RMS values of the biceps brachii during MVIC on the paretic and nonparetic sides. sEMG: surface electromyography; MVIC: maximum voluntary isometric contraction; RMS: root mean square; ; .
