Lingual vibrotactile screening: an investigation of normal sensitivity based on multiple threshold determinations

This report describes a standardized training and sensory screening procedure which was used to obtain 7 separate lingual vibrotactile thresholds for each of 5 normal subjects during a 30-day interval. Baseline observations of lingual sensitivity were highly consistent and occurred within a narrow range of contractor displacements. The authors conclude that the screening method provides a quick and reliable clinical tool for general diagnostic use and discuss directions for continued research applications.
