Abstract
The vestibular-evoked myogenic potential (VEMP) is a sound-evoked reflex recorded by placing surface electrodes on the sternocleidomastoid (SCM) muscles. Recently, VEMPs have been introduced as a clinical test of saccule function. Previous research has established that degradation of the sensorineural structures of the cochlea and semicircular canals occurs with age in humans. However, little research exists on the frequency characteristics of the VEMP response across different age groups. Therefore, the purpose of this experiment was to examine the effects of tone burst frequency on p13 and n23 latencies in young (< 40 years) and middle-aged (40 years +) adults. Tone burst stimuli at 250 Hz, 500 Hz and 1000 Hz were used to record VEMPs in each subject. The results of the study indicated that p13 and n23 latencies were unaffected by the frequency of the stimulus in both age groups. However, slight differences in VEMP latency were seen between age groups, with middle-aged subjects exhibiting prolonged p13 latencies compared to the young subjects. The preliminary results of this study suggest that age-related changes in tone burst VEMP latency occur beginning as early as the fourth decade. Further investigation of the effects of age on tone burst VEMPs is warranted.
