Nerve function impairment after acute vibration exposure

Abstract:
Objective: This study was to investigate the acute effects of hand-arm vibrations on
the nerve functions of the hands, and the impact of the grip force applied to the
vibrating tool during exposure.
Methods: Grip strength and perception of vibration, touch, and temperature were evaluated
using QST before and after vibration exposure in 21 occupationally unexposed individuals.
The procedure was performed twice , with a higher grip force being applied during exposure
on the second occasion.
Results: Vibration perception was significantly impaired after both exposures. Grip strength,
perception of touch and temperature were only significantly affected after the high grip force
exposure.
Conclusions: Exposure to hand-arm vibrations has acute effects on hand nerve function that
are sensitive to the grip force applied during exposure.
