本研究的目的是评估的可靠性的修改版本的市售的生物触觉计，并检查振动触觉感知阈值与年龄和性别。 一个标准化的协议，用于测量振动触觉感知阈值管理80名受试者，每周一次，为期4周。会话间变异性稳定（重复测量的方差分析; P > 0.05），相关性高（Pearson：0.87小于或等于r小于或等于0.90; P小于或等于0.001）。 对于手和脚的部位，随着年龄的增长有显著增加（0.19小于或等于r2小于或等于0.52; P小于或等于0.001）。 五因素方差分析显示，刺激部位、年龄、性别对振动触觉感知阈值的影响有统计学意义，饮酒、吸烟对振动触觉感知阈值的影响无统计学意义。研究结果表明，该设备的测量结果具有高度可重复性，并且对年龄和性别的预期阈值差异敏感。 作者将其归因于对原始设备的技术改进、严格遵守测试方案和维持标准条件。 这种类型的仪器将是有用的，在职业健康研究中评估振动触觉感知损失。
The objective of the present study was to evaluate the reliability of a modified version of the commercially available Biothesiometer, and to examine vibrotactile perception thresholds with respect to age and gender. A standardized protocol for measuring vibrotactile perception threhold was administered to 80 subjects, once a week over 4 weeks. Inter-session variability was stable (analysis of variance for repeated measures; P > 0.05) and correlations were high (Pearson's: 0.87 less-than-or-equal-to r less-than-or-equal-to 0.90; P less-than-or-equal-to 0.001). For sites on both hands and feet, there was a significant increase with age (0.19 less-than-or-equal-to r2 less-than-or-equal-to 0.52; P less-than-or-equal-to 0.001). Five factor analysis of variance model showed that vibrotactile perception threshold was significantly different with stimulus site, age category and gender; no differences were observed with alcohol consumption or smoking status. The findings indicate that the measurements from this device are highly reproducible and sensitive to expected threshold differences with age and gender. The authors attribute this to technical improvements of the original apparatus, rigid adherence to test protocol and maintenance of standard conditions. This type of instrument would be useful in assessing vibrotactile perception loss in occupational health studies.
