Diabetes is the most common cause of peripheral nerve damage and vibration perception is the first sensory modality affected. A standard tuning fork remains the most widely used tool for assessing vibration perception in clinical practice, however inter-operator differences in the use of this tool vary widely. The authors developed a toe manikin capable of reporting the waveform and intensity of vibration imparted to its surface. Using the manikin, the consistency of vibration applied by a group of doctors using a standard 128-Hz tuning fork, with that delivered by the same operator using VibraTip® (McCallan Medical), were compared. Despite differences in technique, the waveform generated with VibraTip was more consistent than that of the tuning fork. With both devices, however, there was considerable intra-operator variability in recorded amplitude and frequency of vibration. By providing instant feedback, the manikin toe serves as a useful training device to encourage consistency of vibration sense testing.
