A study was conducted on the effects of wrist splints on peak power grip strengths as well as the contribution of hand morphology to grip strengths. Peak power grip strengths were measured in 44 female and 52 male subjects with and without the use of a splint wrist brace. The use of the wrist splint decreased the average peak grip strength for all subjects by 13.71%. The difference between grip strengths with and without the use of the splint was statistically significant. No differences were seen between left and right handed subjects however females demonstrated a two fold greater percent decrease compared with males. No anthropometric variables were found to correlate with the dependent variables of change or percent change in peak power grip strength however an analysis of variance indicated that sex and hand length were significant independent variables. Subjects reported that the interference from the bar of the splint decreased their ability to grip the dynamometer and some subjects complained of discomfort from the splint. The implications of these findings were discussed.
