Abstract

The contractile properties of a large proximal muscle (quadriceps femoris) and a small distal muscle (adductor pollicis) have been measured in normal children and children with neuromuscular disorders. The method of stimulating the quadriceps femoris to contract, previously evaluated in adults, was found to be acceptable to children. In normal children a number of indices of muscle function were found to be similar to those in adults. A small study of the function of the adductor pollicis using supramaximal stimulation of the ulnar nerve was carried out in boys with Duchenne dystrophy. Decreased contractile force and prolonged relaxation times from a tetanic stimulation were noted in both the proximal and distal muscles of the boys with Duchenne dystrophy.

摘要

已经对正常儿童和患有神经肌肉疾病的儿童的一块大的近端肌肉（股四头肌）和一块小的远端肌肉（拇收肌）的收缩特性进行了测量。之前在成人中评估过的刺激股四头肌收缩的方法，被发现对儿童也是可行的。在正常儿童中，发现一些肌肉功能指标与成人相似。对患有杜氏肌营养不良症的男孩进行了一项关于使用尺神经超强刺激来研究拇收肌功能的小型研究。在患有杜氏肌营养不良症的男孩的近端和远端肌肉中，均观察到收缩力下降以及强直刺激后的舒张时间延长。
