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

Figure 2

Raw sEMG signals and RMS values of the biceps and brachioradialis during MVIC and FPE on the paretic side. (a) Raw sEMG signals of the biceps brachii and brachioradialis during MVIC. (b) RMS values of the biceps brachii and brachioradialis during MVIC. (c) Raw sEMG signals of the biceps brachii and brachioradialis during FPE. (d) RMS values of the biceps brachii and brachioradialis during FPE. sEMG: surface electromyography. MVIC: maximum voluntary isometriccontraction; FPE: fast passive extension; RMS: root mean square. (red: biceps brachii; blue: brachioradialis).
