Comparative StudySensory perception threshold measurement: an evaluation of semiobjective testing devices.
Five semiobjective devices for testing sensory perception thresholds were concomitantly used on 36 normal subjects to determine normal threshold values, intersubject variability, and their correlation with age. The five devices include the Semmes-Weinstein monofilament (touch); three-point esthesiometer (two-point discrimination); Pfizer thermal tester (temperature); biothesiometer (vibration); and Optacon tactile tester (vibration). Each subject was tested at 12 upper extremity (UE) and ten lower extremity (LE) sites. ⋯ The means of most sites tested for each sensory modality (except vibration tested by the Optacon) showed correlation with age. There was no difference in threshold values between men and women for any sensory modality. The mean values of standard deviation were provided for each peripheral sensory nerve and dermatome.(ABSTRACT TRUNCATED AT 250 WORDS)
