: 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
