摘　　要：通过研究人体上肢运动时的表面肌电(sEMG)信号,探讨人体上肢肌肉功能状态的精确评价指标,及在肌肉功能预测、诊断及康复疗效评价方面的意义,为肌电假肢等康复设备提供设计参数。方法为20个实验对象,左右上肢均完成13个基本动作,每个动作重复3次,采用8通道表面肌电信号采集系统,测试每个受试者完成每个动作时左右上肢三角肌中部、肱二头肌、肱三头肌、掌长肌和指伸肌十块肌肉的表面肌电,对其平均肌电(AEMG)和积分肌电(IEMG)这两个特征参数采用统计处理分析软件SPSS14.0进行数据处理。得到正常成年人体上肢完成日常生活活动(ADLs)时主肌肉群(三角肌中部、肱二头肌、肱三头肌、掌长肌和指伸肌)五块肌肉表面肌电特性。结论是男性与女性在肌肉力量利用方面应有不同的侧重点,提示老年人和残疾人康复训练过程中,男性应以增强指伸肌肌力为重点,而女性应以增强掌长肌肌力为重点。无论男女肱二头肌在ADLs中都很重要,三角肌、肱三头肌作用较小。左右上肢主肌肉群表面肌电特征无显著性差异。同时,AEMG和IEMG这两个分析指标在反映肌肉功能状态方面具有一致性。This study on the surface electromyography（sEMG） characteristics of human upper limb during the Activities of Daily Living （ADLs） was aimed to deliberate over the precise evaluation index for the muscle function of human upper limb, and for the significance of muscle function prediction, diagnosis and rehabilitation evaluation, thus providing the design parameters for prosthetic devices. 20 normal adults （10 males and 10 females） were recruited. They each performed 13 basic actions of left and right upper limb; then they repeated each action 3 times. The sEMG signals of ten muscles （the middle of deltoid, biceps brachii, triceps brachii, palmaris longus, extensor digitorum） were tested by 8-channel sEMG collected system. The eigenvalue of Average electromyography （AEMG） and Integral electromyography（IEMG） were processed by SPSS 14.0. The sEMG characteristics of main muscles （the middle of deltoid, biceps brachii, triceps brachii, palmaris longus, extensor digitorum） during the ADLs were obtained and analyzed. The conclusion is that Man and Woman should be different in using muscle force; man should focus on the strength of extensor digitorum, while woman should enhance the strength of palmaris longus when the elderly and the disabled performed rehabilitation training. Biceps brachii is important both in man and woman during the ADLs; deltoid and triceps brachii are less important. There is no significant difference in sEMG between left and right main muscles. At the same time, AEMG is consistent with IEMG in evaluating the muscle function.
