چکیده انگلیسی
The aim of this study was to investigate muscle activity in the infraspinatus and posterior deltoid and infraspinatus muscle thickness during a prone external rotation (PER) exercise using pressure biofeedback. Fifteen healthy men participated in this study, performing PER exercise with pressure biofeedback under four conditions (comfortable, 2â¯mm Hg, 4â¯mm Hg, and 8â¯mm Hg). Surface electromyography (EMG) was used to monitor infraspinatus and posterior deltoid muscle activity, and ultrasonography was used to collect infraspinatus muscle thickness data. Infraspinatus activity and muscle thickness were greatest at 2â¯mm Hg pressure feedback, and both measures were significantly different from those under other pressure feedback conditions (pâ¯<â¯0.05). In contrast, posterior deltoid activity was lower at 2â¯mm Hg. However, there was no significant difference between any of the four pressure feedback conditions. These findings suggest that PER exercise with pressure biofeedback, particularly at 2â¯mm Hg, is effective in selectively activating the infraspinatus muscle.
