Abstract

Objective: There is little proof to determine the features of the muscles' motor unit potentials (MUPs) in children with poor posture. Current evaluation could be of value for future studies as a reference. The purpose was to detect the impact of rounded back posture on the characteristics of the MUPs and fascicle length of the shoulder retractors in children.

Methods: Participants in this study were 60 children (boys and girls), their ages were from 7 to 10 years old. Children were allocated into healthy children group (A) and rounded back posture group (B). MUPs and fascicle length of middle trapezius were assessed by electromyography and ultrasonography respectively.

Results: When compared to the normal group, the rounded back group's right and left middle trapezius MUPs count and amplitude significantly increased. As regards to the middle trapezius MUPs duration between the two groups, there was no significant difference. Also, the rounded back posture group exhibited significantly lower fascicle length in middle trapezius of both sides than the normal group.

Conclusion: Forward shoulder posture is accompanied by atypical middle trapezius MUPs characteristics and also lowered fascicle length. Thus, children with forward-leaning posture could increase the likelihood of developing any of the many shoulder disorders.

圆背姿势对儿童肩部牵引器运动单元电位和筋膜长度的影响

目的：关于姿势不良儿童肌肉运动单位电位（MUPs）的特征，目前还没有什么证据可以确定。目前的评估可为今后的研究提供参考价值。本研究的目的是检测圆背姿势对儿童肩部牵张肌运动单位电位特征和筋膜长度的影响：本研究的参与者为 60 名儿童（男孩和女孩），年龄在 7 至 10 岁之间。儿童被分为健康儿童组（A）和圆背姿势组（B）。分别用肌电图和超声波检查评估斜方肌中束的MUPs和筋膜长度：结果：与正常组相比，圆背儿童组左右斜方肌中束的MUPs数量和振幅明显增加。两组的中斜方肌MUPs持续时间无明显差异。此外，圆背姿势组两侧斜方肌中部筋膜长度明显低于正常组：结论：肩前倾姿势伴随着不典型的斜方肌中间MUPs特征，同时也会降低筋膜长度。因此，前倾姿势会增加儿童患各种肩部疾病的可能性。

期刊介绍： The Journal of Musculoskeletal and Neuronal Interactions (JMNI) is an academic journal dealing with the pathophysiology and treatment of musculoskeletal disorders. It is published quarterly (months of issue March, June, September, December). Its purpose is to publish original, peer-reviewed papers of research and clinical experience in all areas of the musculoskeletal system and its interactions with the nervous system, especially metabolic bone diseases, with particular emphasis on osteoporosis. Additionally, JMNI publishes the Abstracts from the biannual meetings of the International Society of Musculoskeletal and Neuronal Interactions, and hosts Abstracts of other meetings on topics related to the aims and scope of JMNI.
