To provide clinically useful vibration threshold normal values.
The graduated Rydel-Seiffer tuning fork was evaluated in 198 healthy controls and 59 patients with a polyneuropathy. The measures were done in triplicate at four locations: the distal interphalangeal joint of the index finger, ulnar styloid process, interphalangeal joint of the hallux, and internal malleolus. The values obtained with this tuning fork in healthy controls and patients with polyneuropathy were compared with the values of an electronic device, the Vibrameter.
Vibration sense was better perceived in the arms compared with the legs. There was a significant age related decline of vibration sense at all locations. The values from the Rydel-Seiffer tuning fork and the Vibrameter were significantly correlated in both groups. The sensitivity of these two instruments for the four sites examined in the polyneuropathy group ranged from 29-76% and 31-73%, respectively and was the highest at the hallux for both instruments.
This study provides clinical useful normal values of vibration threshold for the Rydel-Seiffer tuning fork. This is a simple and easily applicable instrument that assesses vibration sense semiquantitatively and should therefore have a place in routine neurological examination.
提供具有临床实用性的振动阈值正常值。
对198名健康对照者和59名患有多发性神经病的患者使用刻度式Rydel-Seiffer音叉进行评估。测量在四个部位重复进行三次：食指远端指间关节、尺骨茎突、拇趾指间关节和内踝。将健康对照者和患有多发性神经病的患者使用该音叉获得的值与电子设备Vibrameter的值进行比较。
与腿部相比，手臂对振动感觉的感知更好。所有部位的振动感觉均存在与年龄相关的显著下降。Rydel-Seiffer音叉和Vibrameter的值在两组中均显著相关。在多发性神经病组中，这两种仪器对所检查的四个部位的敏感性分别为29%-76%和31%-73%，且在拇趾部位两种仪器的敏感性均最高。
本研究提供了Rydel-Seiffer音叉具有临床实用性的振动阈值正常值。这是一种简单且易于应用的仪器，可半定量评估振动感觉，因此应在常规神经学检查中占有一席之地。
