Two studies suggest a possible interaction among sex, motor dominance, and vibrotactile threshold for the great toe and index finger. In study 1 a forced-choice procedure with the Vibratron II (Physitemp Instruments, Inc.) was used; a significant interaction between sex and foot dominance for vibratory threshold was noted with no main effects for the great toe. The greatest difference between men and women was on the nondominant side on the foot. Study 2 replicated Study 1 using the index finger as well as the great toe and used the Semmes. Weinstein monofilament test for a cross-modal comparison. A method of limits procedure was used to increase the generalizability of the data. A similar interaction was found between sex and motor dominance for the index finger but not the great toe. This was attributed to skewing of data for the toe. No effects were found for the Semmes-Weinstein test. Possible usefulness in detecting neuropathies is considered. Larger normative studies including variables such as age, height, and weight are required for generalizable conclusions.
两项研究表明，性别、运动优势以及大脚趾和食指的振动触觉阈值之间可能存在相互作用。在研究1中，使用了Vibratron II（Physitemp仪器公司）进行强制选择程序；观察到性别与足部优势对振动阈值有显著的相互作用，而大脚趾没有主效应。男性和女性之间最大的差异在于足部的非优势侧。研究2重复了研究1，同时使用了食指和大脚趾，并使用Semmes-Weinstein单丝测试进行跨模态比较。采用了极限法程序来提高数据的普遍性。在食指上发现了性别与运动优势之间类似的相互作用，但大脚趾没有。这归因于脚趾数据的偏差。Semmes-Weinstein测试未发现任何影响。考虑了其在检测神经病变方面的可能用途。为了得出可推广的结论，需要进行更大规模的规范性研究，纳入年龄、身高和体重等变量。
