Vibration sensation: Sensitivity and Specificity

Introduction: None written. Excerpt from the entry in Diabetic Neuropathy:

Vibration testing by the on-off method was conducted using a 128-Hz tuning fork applied to the bony prominence bilaterally situated at the dorsum of the first toe just proximal to the nail bed. The patient was asked to report the perception of both the start of the vibration sensation and the cessation of vibration on dampening. The testing was conducted twice on each toe, and correct responses were circled on a standardized sheet. The vibration testing threshold was defined as the total number of times the application of the vibrating tuning fork and the dampening of vibration was not felt, with scores varying between 0 and 8.
