Abstract

Purpose: Quantitative muscle ultrasound (QMUS) is potentially valuable as a diagnostic tool in central neurological disorders, as it provides information about changes in muscle architecture. This study aimed to investigate whether ultrasound images of the submental and masticatory muscles in children with spastic cerebral palsy (CP) differ from those obtained in a reference group, and whether observed ultrasound abnormalities differ between subgroups of children with different Eating and Drinking Ability Classification System (EDACS) levels to support its construct validity.

Methods: A prospective cohort study was conducted in 25 children with spastic CP aged 3-18 years. QMUS of selected muscles was performed. Muscle thickness and echogenicity in the CP group were compared to previously collected reference values, and between different EDACS levels within the CP group.

Results: Median echogenicity of all muscles was significantly higher in children with CP than in healthy controls. The temporalis muscle was significantly thinner in the CP group. There were no differences in muscle thickness or echogenicity between EDACS levels.

Conclusion: QMUS is able to detect abnormal architecture of submental and masticatory muscles in children with spastic CP, but the interpretation of abnormalities in relation to the severity of mastication and swallowing problems needs further investigation.

对脑瘫儿童的下颌和咀嚼肌进行定量超声检查。
目的:肌肉定量超声(QMUS)可提供肌肉结构变化的相关信息,是中枢神经疾病的一种潜在诊断工具。本研究旨在调查痉挛性脑瘫(CP)儿童的下颌肌和咀嚼肌超声图像是否与参照组的图像不同,以及观察到的超声异常在不同饮食能力分类系统(EDACS)水平的亚组儿童中是否存在差异,以支持其构建有效性:对 25 名 3-18 岁的痉挛性 CP 儿童进行了前瞻性队列研究。对选定的肌肉进行了 QMUS 分析。将 CP 组的肌肉厚度和回声性与之前收集的参考值进行比较,并对 CP 组内不同 EDACS 水平的肌肉厚度和回声性进行比较:结果:CP 患儿所有肌肉的回声中位数均明显高于健康对照组。CP 组儿童的颞肌明显较薄。EDACS水平之间的肌肉厚度和回声没有差异:QMUS能够检测出痉挛性CP患儿下颌肌和咀嚼肌的异常结构,但需要进一步研究异常结构与咀嚼和吞咽问题严重程度的关系。
