Examining the effect of the Flextend Orthotic Device on grip strength: a pilot study.

Strengthening exercises like those used to treat carpal tunnel syndrome have been recommended for prevention however their effectiveness when used in this manner are not known. The purpose of this study was to determine the effects of the Flextend Orthotic Device on grip strength of dental hygiene students. This study used a convenience sample of 24 (n=24) first year dental hygiene students. Students were randomly assigned to either the Flextend Orthotic Exercise glove group or a control group. A series of grip strength measurements were taken periodically throughout the study using a hydraulic hand dynamometer. In a repeated measures analysis of covariance there were no significant effects for study group (p=0.812) time (p=0.954), nor was there a significant interaction between group and time (p=0.858). Use of the Flextend Orthotic Device did not additionally increase grip strength among dental hygiene students over the eight week time period. In none of the weeks post baseline was there a significant difference between the Flextend Orthotic Device group and control groups.
