摘要

IntroductionIn the assessment of hand and upper limb function, grip strength is of the major importance. The measurement by dynamometers has been established. Purpose of the StudyIn this study, the effect of a simulated ulnar nerve lesion on different grip force measurements was evaluated. MethodsIn 25 healthy volunteers, grip force measurement was done by the JAMAR dynamometer (Fabrication Enterprises Inc, Irvington, NY) for power grip and by a pinch strength dynamometer for tip pinch strength, tripod grip, and key pinch strength. Study DesignA within-subject research design was used in this prospective study. Each subject served as the control by preinjection measurements of grip and pinch strength. Subsequent measurements after ulnar nerve block were used to examine within-subject change. ResultsIn power grip, there was a significant reduction of maximum grip force of 26.9% with ulnar nerve block compared with grip force without block (P?
