Needle electromyography (EMG) has been an important diagnostic tool, although discomfort may limit its use in some children. We investigated the diagnostic utility of the clustering index (CI) method, a quantitative analysis for surface EMG (SEMG), in children.
SEMG was recorded from the tibialis anterior muscle. Discriminant analysis between patients with neurogenic disorders and patients with myopathy was performed for whole epochs by using the CI and area values.
Forty-five children (29 with myopathy, 16 with neurogenic disorders; age 9 ± 3.9 years) were enrolled. The mean discriminant function value of the neurogenic group was 0.58 ± 0.88 (-0.48-2.30), whereas that of the myopathic group was -0.55 ± 0.70 (-2.38-0.68). When the cutoff value was set at the limit of the other group, 17 of 29 children with myopathy and 7 of 16 children with neurogenic disorders were correctly classified.

虽然针式肌电图（EMG）在诊断中具有重要作用，但它可能会给一些儿童带来不适，从而限制其应用。我们研究了聚类指数（CI）方法在儿童中的应用，CI 方法是一种用于表面肌电图（SEMG）的定量分析方法。
对胫骨前肌进行 SEMG 记录。通过 CI 和面积值，对神经源性疾病患儿和肌病患儿的整个时期进行判别分析。
共纳入 45 名儿童（肌病 29 例，神经源性疾病 16 例；年龄 9±3.9 岁）。神经源性组的平均判别函数值为 0.58±0.88（-0.48-2.30），而肌病组为-0.55±0.70（-2.38-0.68）。当将截断值设置为另一组的极限值时，29 例肌病患儿中有 17 例和 16 例神经源性疾病患儿中有 7 例得到正确分类。
CI 方法可作为神经肌肉疾病患儿有用的非侵入性诊断工具。《肌肉神经》58：824-827，2018。
