Abstract
To detect the sensory disturbances (neurological dysfunction) the vibratory sense has been measured.
This paper describes basic experiments to investigate the relationship between threshold of vibratory sense and skin temperature of finger.
The vibratory sense threshold was measured on the right hands of 15 neurologically healthy subjects: 9 males between 20 and 25 years of age, and 6 females between 21 and 22, and it was determined for the test frequencies 5, 30, 100 and 200Hz.
The results were as follows:
1) The correlation coefficient (r) between the skin temperature and the room temperature is over 0.8 in both males and females. It is obvious that skin temperature is influenced by room temperature.
2) There was no difference between the monthly average of vibratory sense threshold for the frequencies 5, 30 and 100Hz, but the vibratory sense threshold for 200Hz became higher in January in the females.
3) There was a statistically high reverse correlation coefficient between skin temperature and vibratory sense threshold for frequency 200Hz in both males and females. Threshold of vibratory sense for 200Hz was considered to be highly related to the skin temperature.
