Measurement of vibratory perception threshold was carried out on the internal malleoli of 73 healthy subjects and 26 diabetic patients with symptoms of polyneuropathy in their legs. The tests were done first with a tuning fork, using a measuring scale to reflect the amplitude of vibration, and then with an electromagnetic vibrameter (Somedic AB, Stockholm). The results obtained using the vibrameter were much more sensitive than those recorded with the tuning fork (12 and 3 pathological results respectively, in 26 patients). Vibratory perception sensitively reflects disturbances of the function of fast adapting mechanoreceptors and of thick myelinated sensory nerve fibres. The results proved to be readily reproducible. Some variability was noted in the normal values obtained: A further development of the method to exclude the influence of reaction times of patient and investigator on the results might reduce this variability.
对73名健康受试者以及26名腿部有多发神经病变症状的糖尿病患者的内踝进行了振动觉阈值测量。首先使用音叉进行测试，用测量刻度反映振动幅度，然后使用电磁振动计（瑞典斯德哥尔摩的Somedic AB公司生产）进行测试。使用振动计获得的结果比用音叉记录的结果灵敏得多（26名患者中分别有12例和3例病理结果）。振动觉能灵敏地反映快速适应性机械感受器和粗有髓感觉神经纤维功能的紊乱。结果证明很容易重复。在获得的正常值中发现了一些变异性：进一步改进该方法以排除患者和研究者反应时间对结果的影响可能会减少这种变异性。
