摘　　要：目的根据检测的人体上肢表面肌电信号,研究日常生活活动中男性、女性和左右上肢肌肉功能状态的差异性。方法对20个被试者的三角肌中部、肱二头肌、肱三头肌、掌长肌和指伸肌五块肌肉进行肌电采集,每个动作重复3次,采用统计处理分析软件SPSS14.0对时域特征参数平均振幅和积分肌电进行数据处理。结果女性的数值大于男性的数值;左上肢的数值大于右上肢的数值,经t检验知,左右上肢不存在无显著性差异。结论我们可以得到正常人体上肢日常生活活动中的肌电信号数值,为康复治疗、临床诊断、人体工效学提供评定指标。Objective： To explore the difference of muscle states between man and women,left and right upper limb according to the sEMG of human upper limb. Methods： 20 person complete the basic motions,each motion three times,acquisite signal from central deltoid,biceps,triceps,long palmar muscle and extensor muscle of fingers, using SPSS 14.0 statistical analysis software to process data with average amplitude and integrated EMG characteristic parameters. Result： We can see that female data is larger than male data; The left upper data is slightly larger than the right upper,but there is no significant difference,by mean of T test,there is no significant change of left and right upper was observed. Conclusion：We can acquire the healthy adult sEMG data range in daily life and the different between female and male.providing indicators for rehabilitation treatment, diagnosis and assessment of human ergonomics.
