Children with juvenile idiopathic inflammatory myopathies (JIIM) present with muscle inflammation and decreased strength that may affect their functional abilities. The purpose of this study was to determine the intra-rater and inter-rater reliability of the 0 to 10-point manual muscle testing method for children with JIIM.
For the intra-rater and inter-rater reliability studies, 10 and 9 children with JIIM participated, respectively. For intra-rater reliability, one pediatric therapist completed two assessments in one day with a one-hour break. For inter-rater reliability, four therapists assessed the same child within a single morning.
Spearman correlations for intra-rater reliability ranged from 0.70 to 1.00. Kendall's W coefficient for inter-rater reliability of groups of muscles (total, proximal, distal, and peripheral) ranged from 0.51 to 0.76.
The total, proximal, and peripheral Manual Muscle Test (MMT) score, using the 0-10 point scale, has acceptable reliability in JIIM patients.
幼年特发性炎性肌病（JIIM）患儿存在肌肉炎症和肌力下降，这可能会影响其功能能力。本研究的目的是确定JIIM患儿0至10分徒手肌力测试方法的评分者内和评分者间信度。
在评分者内和评分者间信度研究中，分别有10名和9名JIIM患儿参与。对于评分者内信度，一名儿科治疗师在一天内完成两次评估，中间休息一小时。对于评分者间信度，四名治疗师在同一个上午对同一名患儿进行评估。
评分者内信度的Spearman相关性范围为0.70至1.00。肌肉组（总计、近端、远端和外周）评分者间信度的Kendall's W系数范围为0.51至0.76。
使用0-10分制的总计、近端和外周徒手肌力测试（MMT）评分在JIIM患者中具有可接受的信度。
