  • TITLE: Laterality of Accuracy of Grip and Elbow Flexion Force Exertions and Their Differences

    AUTHORS: Hiroki Aoki, Shin-Ichi Demura

    KEYWORDS: Hand Grip Strength, Elbow Flexion Strengths, Laterality

    ABSTRACT: Accuracy of grip and elbow flexion force exertions has been examined. Because agonist muscles related to the achievement of these movements differ, the laterality of their accuracy may also differ. This study aimed to examine the accuracy of grip and elbow flexion force exertions for each demand value and the difference between movements. Participants were 22 right-armed healthy young males (mean age 22.5 ± 5.6 yrs, mean height 170.9 ± 5.8 cm, mean weight 62.4 ± 9.4 kg). Demand values of 25%, 50%, and 75% of maximum voluntary contraction (MVC) were selected. Using subjective judgment, participants were requested to exert each arm’s handgrip and elbow flexion forces for each demand value. Evaluation parameters were differences (errors) between demand and exertion values and their total error. Results of two-way ANOVA (laterality and demand value) showed a significant interaction in grip movement. In results of multiple comparisons, an error in 25% MVC was greater than that in 50% MVC and 75% MVC in the non-dominant arm. For elbow flexion movement, a significant difference was found in a demand value factor, and results of multiple comparisons showed that error was greater in the order of 25% MVC, 50% MVC, and 75% MVC in the non-dominant arm; in the dominant arm, error was greater in 25% MVC than in 50% MVC and 75% MVC. Total error showed significant interaction and was greater in elbow flexion strength than in grip strength in the non-dominant arm. In conclusion, the non-dominant arm had less error with greater demand values in grip and elbow flexion strengths, and laterality was not found in either movement at each demand value. Accuracy of force exertion in elbow flexion strength was inferior to grip strength.
