Abstract In this paper, it is shown that a teddy bear skin spongy mouse is a better option than a conventional plastic mouse design and that a portable arm rest mouse pad platform is far better than the conventional mouse platform placed to the side of the keyboard tray. Both designs help reducing arm abduction and related discomfort, pain, fatigue and soreness. Ten people voluntarily participated in the task and completed a series of psychophysical questions (Borg RPE [Rate of Perceived Exertion] Scale was used to evaluate). Results indicate a much smaller perception of pain and discomfort on palm and wrist with the spongy mouse rather than conventional designs, especially to palmar aponeurosis and ulna muscles. The mouse pad greatly reduced all the pressure points of hand and added comfort on wrist and forearm (e.g. flexor retinaculum (FR) and palmaris longus muscle area).
