Validity and Reliability of the Newly Developed Surface Electromyography Device for Measuring Muscle Activity during Voluntary Isometric Contraction

<div>The relationship between BTS-FREEEMG1000 and PSL-EMG-Tr1 data. Data from 20 participants, for a total of 20 points in each plot. MVIC, maximum voluntary isometric contraction. (a) 40% MVIC (biceps brachii); (b) 80% MVIC (biceps brachii); (c) 40% MVIC (rectus femoris); (d) 80% MVIC (rectus femoris).</div>
