摘要

目的:由于正中神经横截面积的正常值和测量位置的差异,对疑似夹持综合征患者腕关节的超声检查存在严重的局限性。我们的目的是确定在没有腕管综合征的受试者中,不同的人体测量变量对正中神经区域的影响程度。方法:以健康受试者腕部两个特定点的正中神经切割面积为因变量,采用多元线性回归分析进行观察性研究。自变量为性别、年龄、身高、体重、体质指数、手指屈肌力量和腕围。主要结果:正中神经横截面积测量采用二次固定程序归一化。在所有纳入线性回归分析的变量中,只有腕围和性别(0:女性,1:男性)在以腕折痕为测量点的最终模型中贡献显著(常数B=-209.45,腕围系数=21.07,性别系数10.87)。在腕褶远端4厘米处,模型包含相同的变量(常数B=-221.84,腕围系数=24.01,性别系数=11.41)。结论:腕围和性别都是未来正中神经横截面积验证研究中确定正态性分界点时应考虑的变量。

Relationship between anthropometric variables and the cross-sectional area of the median nerve by ultrasound assessment in healthy subjects.

Objective: Ultrasound study of the wrist in patients with suspected entrapment syndrome has severe limitations due to the variability of what is considered normal for the cross-sectional area of the median nerve and where to proceed to measure it. We aim to determine the extent to which different anthropometric variables influence the median nerve area in subjects without carpal tunnel syndrome.

Methods: We conducted an observational study based on a multivariate linear regression analysis using as a dependent variable the area of the median nerve cut at two specific points in the wrist of healthy subjects. The independent variables were sex, age, height, weight, body mass index, finger flexor strength, and carpal circumference.

Major results: The measurements of the median nerve cross-sectional area were normalized using a quadratic fixing procedure. Of all the variables included in the linear regression analysis, only carpal circumference and sex (0: female, 1: male) contributed significantly in the final model using the wrist crease as the measurement point (Constant B=-209.45, carpal circumference coefficient=21.07, sex coefficient 10.87). At four centimeters distal to the carpal fold, the model included the same variables (Constant B=-221.84, carpal circumference coefficient=24.01, and sex coefficient=11.41).

Conclusion: Both the wrist circumference and the sex are variables that should be considered to determine cut-off points of normality in future validation studies about the cross-sectional area of the median nerve.

期刊介绍: Acta Reumatólogica Portuguesa is a scientific peer reviewed journal covering all aspects of rheumatic diseases and related to Rheumatology. The journal publishes original articles, reviews, clinical cases, images in rheumatology, letters to the editor and clinical teaching (e.g. guidelines and clinical protocols). Published since 1973, Acta Reumatológica Portuguesa is the official scientific publication of the Portuguese Society of Rheumatology, a non-profit organization that promotes the knowledge and investigation of rheumatic diseases and the development of Rheumatology.
