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

Figure 5

Correlation between sEMG values (mean and peak RMS values) and elbow flexion (biceps brachii and brachioradialis) muscle strength during MVIC on the paretic side. (a) Correlation between MMT score and mean RMS values of the biceps brachii during MVIC. (b) Correlation between MMT score and peak RMS values of the biceps brachii during MVIC. (c) Correlation between MMT score and mean RMS values of the biceps brachii during MVIC in subgroups (sex, age, stroke type, poststroke duration, and hemiparetic side (left/right)). (d) Correlation between MMT score and peak RMS values of the biceps brachii during MVIC in the subgroups (sex, age, stroke type, poststroke duration, and hemiparetic side (left/right)). (e) Correlation between MMT score and mean RMS values of the brachioradialis during MVIC. (f) Correlation between MMT score and peak RMS values of the brachioradialis during MVIC. (g) Correlation between MMT score and mean RMS values of the brachioradialis during MVIC in subgroups (sex, age, stroke type, poststroke duration, and hemiparetic side (left/right)). (h) Correlation between MMT score and peak RMS values of the brachioradialis during MVIC in the subgroups (sex, age, stroke type, poststroke duration, and hemiparetic side (left/right)). sEMG: surface electromyography; MVIC: maximum voluntary isometric contraction; MMT: manual muscle test; RMS: root mean square.
