摘要
为探究行走时扁平足与正常足女性下肢肌电差异以及足弓支撑鞋垫的作用,实验纳入14名女大学生,正常足穿普通鞋垫(N),扁平足双脚穿足弓支撑鞋垫(FF+ASI)和普通鞋垫(FF)分别行走30 min。使用Trigno无线表面肌电每10 min采集患侧股直肌(RF)、胫骨前肌(AT)、腓骨长肌(PL)、腓肠肌内、外侧头(MHOG)、(LHOG)的均方根振幅(RMS)。FF组与N组RMS比:第1 min LHOG差异具有显著性(P=0.021),PL差异具有极显著性(P=0.006);第10 min PL、MHOG、LHOG具有极显著差异(P=0)、(P=0)、(P=0.001);第20 min PL、LHOG差异具有显著性(P=0.022)、(P=0.016),MHOG具有极显著差异(P=0.006);第30 min PL差异具有显著性(P=0.023),MHOG、LHOG具有极显著差异(P=0.007)、(P=0.007)。FF+ASI与FF相比,第10 min PL具有极显著性差异(P=0.006)。综上,扁平足女性PL、MHOG和LHOG放电水平高于正常足,导致下肢肌肉更易疲劳,穿着足弓支撑鞋垫能够缓解MHOG、RF、AT、LHOG的疲劳。
To investigate the differences in lower limb electromyography between women with flat feet and normal feet during walking,and the effects of arch support insoles,a total of 14 female university students were recruited,with normal feet(N)wearing normal insoles and flat feet walking for 30 minutes on both feet wearing arch support insoles(FF+ASI)and normal insoles(FF),respectively.EMG signals of the rectus femoris(RF),anterior tibialis(AT),longissimus peroneus(PL),medial head of gastrocnemius(MHOG),and lateral head of gastrocnemius(LHOG)on the affected side were obtained using the Trigno wireless surface system,and Root Mean Square(RMS)were collected every 10 minutes.The differences in RMS between FF and N groups:LHOG was significant(P=0.021)and PL was highly significant(P=0.006)at the 1st minute;PL,MHOG and LHOG were highly significant(P=0),(P=0),(P=0.001)at the 10th minute;PL and LHOG were significant(P=0.022),(P=0.016)and MHOG was highly significant(P=0.006)at the 20th minute;PL was significant(P=0.023),MHOG and LHOG were highly significant(P=0.007),(P=0.007)at the 30th minute.The difference in RMS of FF+ASI compared to FF was highly significant only for PL at the 10th minute(P=0.006).In conclusion,women with flat feet showed higher levels of PL,MHOG and LHOG discharge than normal feet,resulting in more fatigue in the lower limb muscles.Fortunately,wearing arch support insoles relieved fatigue in MHOG,RF,AT and LHOG.
