| Popis: | While age-related sensory deficits have been demonstrated for the senses of vision, audition, and the chemical senses, reports have differed with regard to changes in painful and non-painful thermal sensation. One hundred and seventy-nine healthy, community-dwelling individuals aged 20-89 years rated threshold and suprathreshold warming, cooling, and painful stimuli delivered to glabrous (upper lip) and hairy (chin) sites of the face in three separate testing sessions. Threshold measures were determined by the Method of Limits. Suprathreshold stimuli were assessed by a cross-modality matching procedure and a Pooled Adjacent Violators Algorithm-based analysis. The analyses of the effect of age on the threshold and suprathreshold measures of sensory performance yielded disparate findings. There are modest changes in warming and cooling perception with increased age, but pain perception is relatively unaffected. There is a slight diminution in threshold and suprathreshold thermal performance with increasing aging. |
