Summary
The electrically evoked and voluntary contractile properties of the first dorsal interosseous muscle were measured on both hands in 10 healthy adults. The force of abduction of the index finger interosseous muscle was measured using a transducer resting against the lateral side of the proximal interphalangeal joint.
The mean values of time to peak tension measured on the dominant hands were significantly slower than the values on the non-dominant hands (P<0.01) in a pairedt-test. Maximal tetanic tension, maximal voluntary contraction strength, and maximal twitch tension are not significantly different. Fatigue indices on the dominant hands in each subject were higher than those on the non-dominant hands. The correlation coefficient between fatigue indices on the dominant and the non-dominant hand was 0.92 (P<0.01).
