摘　　要：目的探讨个体完成日常生活活动时下肢主要肌肉群肌电信号特征。方法 30名正常成年人完成7个基本动作,同步检测双侧股直肌、股内侧肌、股外侧肌、腓肠肌外侧、胫前肌和比目鱼肌的表面肌电平均肌电值(AEMG)。结果和结论在日常生活活动中,左右下肢肌肉的发力有显著性差异,下肢各肌肉发力有显著性差异,男、女性在完成日常生活活动时下肢发力方式不同。Objective To survey the characteristics of surface electromyography（sEMG） of lower extremity during the activities of daily living（ADL）.Methods 30 normal adults performed 7 basic activities,while their average electromyography（AEMG） of sEMG of rectus femoris,vastus medialis,vastus lateralis,gastrocnemius,anterior tibialis,and soleus was determined.Results and Conclusion The AEMG of lower limbs during the ADL was different in left or right,male or female,and different muscles.
