Abstract
|
|
|
To evaluate vibration perception threshold (VPT) by the bone vibrator of audiometer, VPT of forty healthy young adults were tested and retested after one week on their various anatomical sites at 250Hz.
Mean VPTs were distributed from 16.88 to 37.20dB and were tended to be lower in upper than lower extremities. Coefficients of variation (C.Vs) of them were ranged 14.60 to 32.37%. Correlation coefficients of VPT between test and retest after 1
week
were
very high as 0.86 to 0.99 (p<0.01).
This result suggests that a bone vibrator of audiometer may be useful in measuring VPT.
