Reliability and Validity of Electrogustometry and its Application to Young and Elderly Persons

Abstract

Electrogustometric-threshold assessment demonstrated excellent test-retest reliability, good bilateral correspondence and age-related differences. Tactile and stimulus-related descriptors of the sensation elicited at detection threshold, as well as a lack of correlation between whole-mouth chemical thresholds and anterior tongue electrogustometric thresholds, raise questions for future research.
