Characteristics of the surface recorded F-response, including frequency, occurrence of identical responses, shape and amplitude have been investigated in the ulnar nerve of control subjects. During a train of 200 stimuli, F-response frequency varied between 50% and 93% in different subjects with a mean of 79%. The vast majority of responses (96.6%) occurred only once; of those responses which repeated, 89.5% occurred between 2-5 times, 9% between 6-10 times and only 1.5% 11 or more times. F-response shape was variable, the majority containing two or more negative peaks. F-response amplitudes tended to be a relatively small proportion of the compound M-response, with median F%M values ranging from 0.8% to 4%. The data suggest that a large proportion of surface recorded F-responses following supramaximal stimulation are composed of recurrent discharges derived from more than one motor unit.
已对健康受试者尺神经表面记录的F波特性进行了研究，包括频率、相同反应的发生率、形状和波幅。在一串200次刺激中，不同受试者的F波频率在50%至93%之间变化，平均为79%。绝大多数反应（96.6%）仅出现一次；在重复出现的反应中，89.5%出现2至5次，9%出现6至10次，仅1.5%出现11次或更多次。F波形状各异，大多数包含两个或更多负向波峰。F波波幅在复合肌肉动作电位（M波）中所占比例相对较小，F/M值中位数范围为0.8%至4%。数据表明，超强刺激后表面记录的大部分F波由来自多个运动单位的折返放电组成。
