Influence of age, temperature, sex, height and diazepam on vibration perception.
Vibration perception was quantitatively examined in 92 healthy volunteers (46 females, 36 males, aged 10-71 years). Vibration perception thresholds, vibration disappearance thresholds and vibration thresholds were assessed at the second metacarpal bone, styloid process of ulna, lateral epicondyle of humerus, first phalanx of the big toe, first metatarsal bone, medial malleolus and proximal part of the tibia bilaterally. Vibration sensitivity was found to be age-dependent. Under the age of 60, the correlation was linear. Vibration thresholds depended on body site but they were not related to sex or body side. Temperature and diazepam affect the perception of vibration considerably. Small interindividual variability was found in measurements repeated in 3 consecutive days, after 4 weeks and after a year.
