BACKGROUND & AIMS: Adductor pollicis muscle is the only muscle which could be directly assessed, and its thickness could be useful in muscle mass assessment. Our objective is to determine values of adductor pollicis muscle thickness (APMT) in healthy subjects.
APMT was obtained using a skinfold caliper in 300 healthy subjects, grouped by age and gender, in dominant (DAPMT) and non-dominant (NDAPMT) sides. All patients were assessed by Subjective Global Assessment (SGA). General characteristics of the subjects were obtained by a questionnaire.
One hundred and fifty men and one hundred and fifty women were evaluated. Their mean age was 44.9+/-18.5 years and they were all well nourished. DAPMT mean values found in men were 26.1+/-4.4mm and in women, 19.8+/-3.3mm, respectively. NDAPMT mean values found in men and women were 25.1+/-4.4mm and 18.7+/-3.1, respectively. Reference values for each gender and age group were created and values below the 5th percentile were considered as limit of normality.
This study presents APMT reference values from a healthy population. New studies may demonstrate its role in the evaluation of muscle mass and its association with nutritional status.
拇内收肌是唯一可直接评估的肌肉，其厚度可用于评估肌肉质量。本研究旨在确定健康受试者拇内收肌厚度（APMT）的正常值。
使用皮褶卡尺测量 300 名健康受试者（按年龄和性别分组）的优势（DAPMT）和非优势（NDAPMT）侧的 APMT。所有患者均采用主观综合评估（SGA）进行评估。通过问卷调查获得受试者的一般特征。
共评估了 150 名男性和 150 名女性，平均年龄为 44.9±18.5 岁，营养状况良好。男性的 DAPMT 平均值为 26.1±4.4mm，女性为 19.8±3.3mm。男性和女性的 NDAPMT 平均值分别为 25.1±4.4mm 和 18.7±3.1mm。为每个性别和年龄组创建了参考值，低于第 5 个百分位数的值被认为是正常范围的极限。
本研究提供了健康人群的 APMT 参考值。进一步的研究可能会表明其在肌肉质量评估及其与营养状况的关系中的作用。
