The influence of insertion of a needle into muscle on the activity of creatine kinase and fructose-1,6-diphosphate aldolase in serum was measured in 23 patients undergoing electromyography because of suspected neurogenic (n = 18) or myogenic (n = 5) muscular atrophy. Myogenically atrophied muscle was easily vulnerable. In neurogenic atrophy and in healthy muscle the lesion was demonstrable in enzyme changes only when muscular work followed the insertion of the needle. Activity of so-called muscle enzymes is not only changed after intramuscular injections but also due to insertions of thin electrodes (electromyography). The vulnerability of muscules may provide information on the activity of an atrophying process.
对23例因疑似神经源性（n = 18）或肌源性（n = 5）肌肉萎缩而接受肌电图检查的患者，测量了肌肉内针刺入对血清中肌酸激酶和果糖-1,6-二磷酸醛缩酶活性的影响。肌源性萎缩的肌肉很容易受到影响。在神经源性萎缩和健康肌肉中，只有在针刺入后进行肌肉活动时，酶变化才能显示出病变。所谓的肌肉酶活性不仅在肌肉注射后会发生变化，而且由于细电极的插入（肌电图检查）也会发生变化。肌肉的易损性可能提供有关萎缩过程活动的信息。
