Table 1.

Summary of field-testing to document FTV in underground mining and reported symptoms of pain/ache/discomfort in the hands and feet. Mean frequency weighted RMS acceleration and standard deviations are reported along with the percentage of operators who reported pain/ache/discomfort in the hands or feet
