AI Article Synopsis

  • Hand-arm vibration syndrome (HAVS) is a common health issue for workers using vibration tools, often diagnosed too late.
  • A study of 326 men aged 25-45 found that nearly 40% reported HAVS symptoms, especially those with over 10 years of experience or using tools for more than 20 hours weekly.
  • Despite 75% feeling informed about risks by their employers, those who were self-reportedly well-informed experienced symptoms more frequently, highlighting the need for better awareness and education to prevent HAVS.

Article Abstract

Hand-arm vibration syndrome (HAVS) is a significant occupational health issue, often diagnosed at an advanced stage. This study aimed to assess the prevalence of HAVS (vascular and neurological components) among men exposed to local vibrations in their workplace. A questionnaire survey was conducted among 326 men aged 25-45 years, each with at least 5 years of experience using vibration tools. Results indicated that nearly 40% of participants reported at least one symptom of HAVS, with symptoms being more common among those working with vibration tools for more than 10 years or more than 20 h per week. Notably, 75% of respondents believed they were well informed by their employers about the health risks of local vibrations, and workers who considered themselves well-informed reported symptoms more frequently than those who did not. These findings underscore the importance of self-awareness and education in the prevention and early detection of HAVS.

Recommendation of occupational exposure limits (2024-2025).

Environ Occup Health Pract

September 2024

The Japan Society for Occupational Health (JSOH) recommends the Occupational Exposure Limits (OELs) as reference values for preventing adverse health effects on workers caused by occupational exposure to chemical substances, continuous or intermittent noise, impulsive or impact noise, heat stress, cold stress, whole-body vibration, hand-arm vibration and time-varying electric, magnetic and electromagnetic fields and ultraviolet and ionizing radiation.

Background: Since over century it has been known that hand to arm transmitted vibrations (HAV) can affect health and quality of life. Exposure over certain level and intensity over time are risk causes of Hand Arm Vibration Syndrome (HAVS). Symptoms varies from the damaged structures which most commonly are secondary Raynaud Phenomenon known as Vibration Induced White Finger (VWF), carpal tunnel syndrome, tingling, loss of manual dexterity, osteoarthritis or even Dupuytren's contracture.

When holding or carrying vibrating machines, the coupling forces play a major role in transmitting the vibrations to the hand-arm system. In an epidemiologic study, two recommended methods from ISO/TS 15230-2 are used to investigate the relationship between coupling force-adjusted vibration exposures and their related risk of musculoskeletal disorders of the upper limb. Therefore, coupling forces have been professionally estimated for 408 machines used by 683 male participants during their entire working life and coupling force-adjusted long-term vibration doses are calculated.

Knockdown of LncRNA MEG3 promotes damage of vascular endothelial cells induced by vibration.

Hand-arm vibration syndrome (HAVS) is caused by long-term exposure to hand-transmitted vibration (HTV), and its pathogenesis has not been elucidated fully. We explored the molecular mechanism of HAVS and provided clues and a theoretical basis for the early prevention and treatment of HAVS. After vibration, samples were collected from the plasma of human workers, plasma of rat tails, and human umbilical vein endothelial cells (HUVECs).
