Three patients with adult-acquired hemiplegia are described with the unusual dynamic deformity of spasticity of the triceps muscle. This deformity produces motor imbalance with the triceps overpowering the elbow flexors, thus impeding volitional elbow flexion. The nature of the deformity was defined by electromyography of the muscle groups about the elbow, which demonstrated out-of-phase inhibitory electrical activity of the triceps muscle. Treatment consisted of V-Y lengthening of the triceps muscle to achieve agonist-antagonist motor balance. The operation improved hand placement for all three patients.
本文描述了3例成人获得性偏瘫患者，他们存在肱三头肌痉挛这一不寻常的动态畸形。这种畸形导致运动失衡，肱三头肌力量超过肘屈肌，从而妨碍了主动的屈肘动作。通过对肘部周围肌肉群进行肌电图检查明确了畸形的性质，结果显示肱三头肌存在异相抑制性电活动。治疗方法为肱三头肌V-Y延长术，以实现主动肌-拮抗肌的运动平衡。手术改善了所有3例患者的手部摆放。
