A new psychiatric research method for measuring infant muscle tone using quantified electromyography is described. Muscle tone was assessed electromyographically from the arms and legs of 44 neonates; 18 offspring of drug abusing women, 26 control infants. Infants from the drug group had higher muscle tone than control infants. There was also a tendency for smaller infants and females to have higher muscle tone. Electromyographic assessments of tone were correlated with examiners' clinical assessments, but tended to be more sensitive to tone in specific muscle groups.
描述了一种使用量化肌电图测量婴儿肌张力的新的精神病学研究方法。通过肌电图对44名新生儿的手臂和腿部肌张力进行评估；其中18名是滥用药物女性的后代，26名是对照婴儿。药物组婴儿的肌张力高于对照婴儿。较小的婴儿和女性也有肌张力较高的趋势。肌张力的肌电图评估与检查者的临床评估相关，但对特定肌肉群的肌张力往往更敏感。
