[Purpose] This study compared the EMG activities of the plantarflexor and dorsiflexor muscles during inclined walking with and without modified mobilization with movement (modified MWM) using tape in women with limited ankle dorsiflexion. [Subjects] Fifteen women with limited dorsiflexion in their feet (22 feet in total) were recruited for this study. [Methods] The subjects walked with and without modified MWM using tape on a treadmill at 6 degrees with a speed of 1.25 m/s for 5 minutes. The EMG activities of the medial gastrocnemius (GCM) and tibialis anterior (TA) muscles were measured using a surface EMG system. [Results] During incline walking with modified MWM using tape, the mean EMG activity of the GCM significantly increased, and that of the TA decreased between heel strike and heel off. There was no difference between heel off and toe off in the two muscles. [Conclusions] Modified MWM using tape on the talus during incline walking could alter the muscle activities of the GCM and TA between heel strike and heel off in women with limited ankle dorsiflexion.
[目的] 本研究比较了在有或没有使用胶带进行改良动态关节松动术(modified MWM)的情况下,踝关节背屈受限女性在斜坡行走时跖屈肌和背屈肌的肌电图活动。[对象] 招募了15名足部背屈受限的女性(共22只脚)参与本研究。[方法] 受试者在跑步机上以6度倾斜、1.25米/秒的速度行走5分钟,期间有或没有使用胶带进行改良MWM。使用表面肌电图系统测量腓肠肌内侧头(GCM)和胫骨前肌(TA)的肌电图活动。[结果] 在使用胶带进行改良MWM的斜坡行走过程中,足跟触地到足跟离地期间,GCM的平均肌电图活动显著增加,TA的平均肌电图活动降低。在足跟离地到足趾离地期间,两块肌肉之间没有差异。[结论] 在斜坡行走时对距骨使用胶带进行改良MWM,可改变踝关节背屈受限女性在足跟触地到足跟离地期间GCM和TA的肌肉活动。
