这项回顾性调查的目的是确定肩部内侧(内部)旋转肌和肘屈肌的静态力量缺陷与这些肌肉或其拮抗者的痉挛之间是否存在关系。我们回顾了最初50名符合研究入选标准的中风偏瘫患者的记录，这些患者在四个月的时间内入院。用手持测功法测量静态肌力。痉挛状态按阿什沃思量表进行分级。Kendall的tau相关性在静态肌肉力量缺陷和痉挛之间进行了计算。肩部内侧旋转肌和肘屈肌的静态力量缺陷与主动肌的痉挛程度相关(p<；.01)，而与对抗肌的痉挛程度无关。因此，肌群痉挛和力量不足似乎是脑血管意外的共同表现。因此，临床医生可能会根据肌肉本身的音调而不是根据其拮抗者的音调来解释激动肌的力量产生能力。
The purpose of this retrospective investigation was to determine whether a relationship exists between static strength deficits in the shoulder medial (internal) rotator and elbow flexor muscles and spasticity in these muscles or their antagonists. We reviewed the records of the first 50 stroke patients with hemiparesis who met the entry criteria for the study and who were admitted over a four-month period of time. Static muscle strength was measured by hand-held dynamometry. Spasticity was graded on the Ashworth scale. Kendall's tau correlations were calculated between static muscle strength deficits and spasticity. Static strength deficits of the shoulder medial rotator and elbow flexor muscles were correlated (p< .01) with the agonist muscles' spasticity, but not with the antagonist muscles' spasticity. Muscle group spasticity and strength deficits, therefore, appear to be covarying manifestations of cerebrovascular accidents. Clinicians, thus, may interpret an agonist muscle's capacity for force production in light of its own tone rather than that of its antagonist.
