Abstract

INTRODUCTION

This study was undertaken to describe a method for quantifying vibration when using a conventional tuning fork (CTF) in comparison to a Rydel-Seiffer tuning fork (RSTF) and to provide reference values.

METHODS

Vibration thresholds at index finger and big toe were obtained in 281 participants. Spearman's correlations were performed. Age, weight, and height were analyzed for their covariate effects on vibration threshold. Reference values at the fifth percentile were obtained by quantile regression.

RESULTS

The correlation coefficients between CTF and RSTF values at finger/toe were 0.59/0.64 (P = 0.001 for both). Among covariates, only age had a significant effect on vibration threshold. Reference values for CTF at finger/toe for the age groups 20-39 and 40-60 years were 7.4/4.9 and 5.8/4.6 s, respectively. Reference values for RSTF at finger/toe for the age groups 20-39 and 40-60 years were 6.9/5.5 and 6.2/4.7, respectively.

DISCUSSION

CTF provides quantitative values that are as good as those provided by RSTF. Age-stratified reference data are provided. Muscle Nerve 57: 49-53, 2018.

摘要

引言

本研究旨在描述一种在使用传统音叉（CTF）与赖德尔 - 赛弗音叉（RSTF）时量化振动的方法，并提供参考值。

方法

对281名参与者的食指和大脚趾的振动阈值进行测量。进行斯皮尔曼相关性分析。分析年龄、体重和身高对振动阈值的协变量效应。通过分位数回归获得第五百分位数的参考值。

结果

手指/脚趾处CTF和RSTF值之间的相关系数分别为0.59/0.64（两者P = 0.001）。在协变量中，只有年龄对振动阈值有显著影响。20 - 39岁和40 - 60岁年龄组手指/脚趾处CTF的参考值分别为7.4/4.9和5.8/4.6秒。20 - 39岁和40 - 60岁年龄组手指/脚趾处RSTF的参考值分别为6.9/5.5和6.2/4.7。
