Abstract
Finger tip sensation was measured in normal subjects and diabetic patients using an instrument that converts visual images to tactile forms (Optacon). Vibration threshold detection values were measured in 100 normal subjects and 24 diabetic patients. Voltage at threshold was positively correlated with age. Thresholds of 38 percent of the patients were significantly higher than the comparisons. Six of the nine subjects who displayed an apparent sensory deficit using the Optacon had peripheral neuropathy. The remaining three subjects with elevated thresholds and all of the clinical subjects with normal thresholds had no symptoms or signs of neurological impairment. The authors conclude that the modified optacon is a reliable device for the rapid assessment of finger tip sensation and is potentially useful for the repeated screening for peripheral nerve dysfunction in large populations.
