Electrical activity during voluntary effort was analysed in 33 normal subjects. Parameters of activity measured were number of peaks, mean amplitude, distribution of time intervals and of amplitudes between peaks. Recording from 10 sites evenly distributed over a muscle gave adequate representation of activity; force should be a fixed proportion of maximum rather than constant.
对33名正常受试者在自主用力过程中的电活动进行了分析。所测量的活动参数包括峰值数量、平均幅度、时间间隔分布以及峰值之间的幅度分布。从一块肌肉上均匀分布的10个部位进行记录,能充分反映活动情况;用力程度应是最大用力的固定比例,而非恒定不变。
