Mechanomyographic (MMG) signal during a voluntary muscle action. Example of the raw mechanomyographic (MMG) signal from the biceps brachii muscle and the torque production curve during a concentric isokinetic muscle action of the forearm flexors at 100% peak torque (PT) for one subject. The concentric muscle action was performed at a velocity of 30°·s^-1 across a 90° range of motion (180° to 90° of forearm flexion), and the MMG signal was recorded with an accelerometer (Entran EGAS FT 10).
