多数脑部损伤患儿患侧手指肌张力大，拇指呈内收状态，无法完成手指的张合动作，存在着手功能损伤。然而，临床上患儿手功能康复训练方式单调枯燥，不符合患儿的心理特点。该文设计了一种基于患儿心理特点的利用声、光信号诱导患儿主动训练的电子手套，并在中国康复研究中心进行了临床实验。实验表明：患儿患侧手指表面肌电信号的中位频率在康复训练后增大，说明用手套进行康复训练使患儿患侧肌肉耐力提高；静息状态下，患侧大鱼际肌与拇长伸肌表面肌电信号均方根与平均幅值在康复训练后减小，表明静息状态下大鱼际肌与拇长伸肌肌张力下降，患儿患侧手指运动控制能力增强。实验结果验证了该电子手套在脑部损伤患儿手功能康复训练中的有效性。
Abstract
The hand motor functions of brain damaged children are limited because of high muscle tension. These children cannot easily extend or flex their fingers because of the muscle tension. There is currently little equipment developed for young patients. The aim of this study is to design gloves based on child's psychology to attract the children to actively participate in rehabilitation training. The gloves attract the children's attention by a series of LEDs that turn on or off as well as music playing or stopping. The gloves have been used by brain damaged children in the China Rehabilitation Research Center with results showing that the median frequencies of affected thenar and extensor proprius longus increase, which indicates that the muscle endurance is improved. The root-mean-square and average amplitude of the thenar and extensor proprius longus decrease, suggesting that the muscle tension decreases and the ability to control their fingers motion improves. The results verify the effectiveness of these gloves with brain damaged children.
