The effect of selected rest break activities on reaction time, balance, and perceived discomfort after one hour of simulated occupational whole-body vibration exposure in healthy adults.

A 5-minute intervention activity after 1 hour of occupational whole-body vibration (WBV) exposure may provide protection against detriments in reaction time.Intervention activities that include a gaze stabilization exercise component maintained the slowest reaction speeds after 1 hour of WBV exposure, whereas sitting and walking activities resulted in a further slowing of the slowest reaction speeds.It may be possible for machinery operators to incorporate gaze stabilization activities in occupational environments, either in or out-of-cab, but further evaluation for feasibility and practicality of in-field adoption is required.
