From: Parkinson patients without tremor show changed patterns of mechanical muscle oscillations during a specific bilateral motor task compared to controls

Figure 1

Setting of the bilateral motor task. (a) Measuring position for recording the acceleration, force and mechanical muscular oscillations (MMGs) of the biceps brachii, brachioradialis and pectoralis major muscles during the bilateral isometric muscle action. The subject had to push its hands from each side against the interface and intrapersonal reaction force of both arms. (b) Illustrates the strain gauge with interfaces for the bilateral task and the piezoelectric sensor for recording the MMGs.
