In a prospective study of 93 electromyographic examinations including those of 42 men and 51 women, various factors relating to the experience were correlated with pain levels. Patients were asked to record their pain levels, and electromyographers were asked to record their perception of the patients' levels of pain on a scale of 0 to 4. It was found that the pain reported was not related to length of wait or of examination, number of surface areas studied, whether the findings on examination were normal or abnormal, the age of the patient, time of day, the electromyographic findings or the characteristics of the examiner. The data suggested that nerve conduction velocity studies are more uncomfortable for patients than needle electromyographic studies. The only other statistically significant factor appeared to be the patient's sex. All of the patients who reported no pain were male while 86% of the patients reporting maximum pain were females. The electromyographer's evaluation of the patient's pain perception was accurate in 84% of the cases.
在一项对93例肌电图检查的前瞻性研究中（其中包括42名男性和51名女性），将与该检查经历相关的各种因素与疼痛程度进行了关联分析。患者被要求记录他们的疼痛程度，肌电图检查人员则被要求按照0至4的等级记录他们对患者疼痛程度的感知。结果发现，报告的疼痛与等待时间或检查时间、所研究的体表区域数量、检查结果是正常还是异常、患者年龄、一天中的时间、肌电图检查结果或检查人员的特征均无关。数据表明，与针电极肌电图检查相比，神经传导速度检查让患者感觉更不舒服。唯一另一个具有统计学意义的因素似乎是患者的性别。所有报告无疼痛的患者均为男性，而报告疼痛程度最高的患者中86%为女性。肌电图检查人员对患者疼痛感知的评估在84%的情况下是准确的。
