Figure 2. — Schematic diagram showing operation of the complete WBV system; the direction of the arrow represents the flow of the signal. The top part depicts interfacing of the controlling PC with the vibration device, through opto-coupler circuitry, motor drive and vibrating motors. This top part also depicts how sensors attached to the vibration device (i.e., load cell and accelerometer) were interfaced with the controlling PC. The bottom part of the figure depicts how sensors attached to the vibration device user (i.e., EMG and accelerometer sensor) were connected to the controlling PC. sEMG: surface electromyography.
