초록
Objective : The objective of this study was to determine the optimal method for selective activation of the subscapularis muscle among the following three strengthening techniques in healthy individuals. Methods : Fifteen healthy individuals participated in the experiment, and muscle strength and electromyography (EMG) data were collected using handheld dynamometry and surface EMG tools. To compare the subscapularis strength and pectoralis major muscle activity using the three methods, a one-way analysis of variance with repeated measures was used, with the level set at .05. Results : Significant differences in subscapularis muscle strength were observed between the three methods (F = 51.318, p < .05). There was significant difference between the belly press and bear hug and between the belly press and side-lying wiper internal rotation (padj = .00). In the pectoralis major EMG data, significant differences were noted among the three methods (F = 61.679, p < .05). The largest increase in muscle activity was observed with the belly press, and the lowest activity was noted with SWI (padj = .00). Conclusion : The best method for selectively evaluating or improving subscapularis muscle strength was SWI. Based on the results of this study, we recommend that clinicians perform SWI to accurately evaluate and improve impaired subscapularis muscle strength.
