Vibrotactilometry with testing of the thresholds of the vibration sense at seven frequencies between 8-500 Hz in different intensities has been correlated with nerve conduction studies of the ulnar nerve to evaluate its diagnostic power in neuropathies at the elbow. Thirty-nine patients with entrapment symptoms were studied. Vibrotactilometry was abnormal in 33 patients (85%) and nerve conduction studies were abnormal in 19 (49%). The sensitivity of vibrotactilometry in relation to nerve conduction studies was 89%, and in relation to the patients' symptoms was 85%. We conclude that vibrotactilometry is a sensitive test that correlates well with the patients' symptoms, while nerve conduction studies are less sensitive (49%) in relation to the patients' symptoms. Vibrotactilometry in the frequency area of 8-500 Hz is recommended in the screening of ulnar nerve entrapment. Nerve conduction studies are recommended in clinically doubtful cases to localise the entrapment to the elbow region.
通过在8 - 500赫兹之间的七个频率下、以不同强度测试振动觉阈值的振动触觉测量法，已与尺神经的神经传导研究相关联，以评估其在肘部神经病变中的诊断能力。对39例有卡压症状的患者进行了研究。33例患者（85%）的振动触觉测量结果异常，19例（49%）的神经传导研究结果异常。振动触觉测量法相对于神经传导研究的敏感性为89%，相对于患者症状的敏感性为85%。我们得出结论，振动触觉测量法是一种敏感的测试方法，与患者症状相关性良好，而神经传导研究相对于患者症状的敏感性较低（49%）。在尺神经卡压的筛查中，建议采用8 - 500赫兹频率范围内的振动触觉测量法。对于临床诊断存疑的病例，建议进行神经传导研究，以将卡压部位定位到肘部区域。
