High-Frequency Vibration from Hand-Held Impact Wrenches and Propagation into Finger Tissue

Proceedings, 2023
High-frequency shock-type vibration (HFV) with a frequency content mainly above 1250 Hz, e.g., from impact wrenches, is likely to cause a significant amount of vibration injuries and even hand-arm vibration syndrome.

Arterial abnormalities in the hands of workers with vibration white fingers – a magnetic resonance angiography case series

Journal of Occupational Medicine and Toxicology, 2021
Vibration white finger (VWF) is a complication from exposure to hand-arm vibrations. Poor knowledge of the pathophysiology of VWF means that making an accurate prognosis is difficult. Thus, a better understanding of VWF’s pathophysiology is of importance.

Hand-Arm Vibration Syndrome Associated with Impact Vibration

Journal of Low Frequency Noise, Vibration and Active Control, 1995
The data from 141 hand-arm vibration exposed workers examined for hand-arm vibration syndrome (HAVS) was analyzed in a Cox regression model to determine whether smoking, alcohol, the use of gloves, duration of weighted vibration exposure, and vibration impulsiveness affected the rate of onset of Raynaud's phenomenon. The results show that workers with
