Abstract

Developmental delays cover a wide range, with different movement characteristics occurring depending on differences in muscle tone. We aimed to investigate muscle activity and acceleration during sit-tostand in developmentally delayed (DD) children with different muscle tones. Forty participants were divided into three groups: typically developing (TD) children (n= 18), DD children with hypertonia (n= 12), and DD children with hypotonia (n= 10). Electromyography was used to measure muscle activity and BTS G-Walk was used to measure acceleration. As a result, the activities of the rectus abdominal muscle and quadriceps muscle were lower in DD children with hypertonia than in TD children (P< 0.05). The activity of the tibialis anterior muscle was higher in DD children with hypotonia than in TD children (P< 0.05). The trunk angle was greater in DD children with hypotonia than in TD children (P< 0.05), and vertical acceleration was lower in DD children with hypertonia than in TD children (P< 0.05). Based on these differences, we will be able to provide intervention programs appropriate for the characteristics of DD children with different muscle tone.

肌张力不同的发育迟缓儿童在坐立过程中的肌肉活动和加速度也不同

发育迟缓的范围很广，根据肌肉张力的不同，会出现不同的运动特征。我们旨在研究不同肌张力的发育迟缓（DD）儿童在坐立时的肌肉活动和加速度。我们将 40 名参与者分为三组：典型发育（TD）儿童（18 人）、肌张力过高发育迟缓儿童（12 人）和肌张力过低发育迟缓儿童（10 人）。肌电图用于测量肌肉活动，BTS G-Walk 用于测量加速度。结果显示，腹直肌和股四头肌的活动量在患有肌张力过高症的发育迟缓儿童中低于患有肌张力过低症的儿童（P< 0.05）。肌张力过低的聋哑儿童的胫骨前肌活动量高于智力发育迟缓的儿童（P< 0.05）。肌张力过低的残疾儿童的躯干角度大于患有肌张力过高的残疾儿童（P< 0.05），垂直加速度低于患有肌张力过高的残疾儿童（P< 0.05）。根据这些差异，我们将能够针对不同肌张力的 DD 儿童的特点提供合适的干预方案。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
