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

Figure 6

Correlation between sEMG values (mean and peak RMS values) and elbow flexion (biceps brachii and brachioradialis) muscle tension during FPE on the paretic side. (a) Correlation between MAS score and mean RMS values of the biceps brachii during FPE. (b) Correlation between MAS score and peak RMS values of the biceps brachii during FPE. (c) Correlation between MAS score and mean RMS values of the biceps brachii during FPE in the subgroups (sex, age, stroke type, poststroke duration, and hemiparetic side (left/right)). (d) Correlation between MAS score and peak RMS values of the affected biceps brachii during FPE in the subgroups (sex, age, stroke type, poststroke duration, and hemiparetic side (left/right)). (e) Correlation between MAS score and mean RMS values of the brachioradialis during FPE. (f) Correlation between MAS score and peak RMS values of the brachioradialis during FPE. (g) Correlation between MAS score and mean RMS values of the brachioradialis during FPE in the subgroups (sex, age, stroke type, poststroke duration, and hemiparetic side (left/right)). (h)Correlation between MAS score and peak RMS values of the brachioradialis during FPE in the subgroups (sex, age, stroke type, poststroke duration, and hemiparetic side (left/right)). sEMG: electromyography; FPE: fast passive extension; MAS: modified Ashworth scale; RMS: root mean square.
