Abstract |
Risk factors present during forearm pronated (FP) mounse use that were associated with the development of forearm and wrist cumulative trauma disorders (CTD) were investigated. A forearm neutral (FN) mouse design eliminated the postural and joint motion risk factors and reduced some of the muscular demands associated with the postural risks. An increase of 5 to 10 degrees in the grip angle of the FN mouse design was proposed so that the mean wrist deviation angle would be offset from neutral by 5 to 10 degrees of ulnar deviation, and movement would oscillate between neutral and 10 to 15 degrees of ulnar deviation. This would reduce the occurrence of high wrist radial deviation angles and lower demands on the extensor carpi radialis longus and brevis muscle, but also it may improve performance. The authors conclude that risk factors for forearm and wrist CTD are attributable to mouse operation. |
