Occupational biomechanical risk factors for surgically treated ulnar nerve entrapment in a prospective study of male construction workers
Evidence was provided for forceful hand-grip work, with and without vibration, as a risk factor for ulnar nerve entrapment (UNE) surgery in a large cohort of Swedish construction workers. Several individual biomechanical factors comprising such work were associated with increased risk of UNE, including: increased grip force, upper extremity load, frequency of hand-held tool use, and hand arm vibration.

A critical review of evidence related to hand-arm vibration syndrome and the extent of exposure to vibration
This report describes a systematic literature review on the nature of the exposure-response relationship between hand-transmitted vibration and the elements of hand-arm vibration syndrome (HAVS), ie the vascular, neurosensory and musculoskeletal components. Annex C of ISO 5349-1:2001 contains an exposure-response relationship for vascular HAVS, yet this review of the literature has not found any strong evidence of a precise quantitative relationship between exposure to vibration and health outcomes, either for vascular or neurosensory HAVS. There is some evidence that suggests possible limited...
Outils vibrants
Paramètres biomécaniques et sensorimoteurs affectant la réponse biodynamique du système main-bras L'exposition aux vibrations est une préoccupation importante au regard de la prévention des troubles musculo-squelettiques aux membres supérieurs. Les vibrations main-bras sont spécifiquement reconnues pour être la cause du syndrome des vibrations, une maladie atteignant les doigts et la main en matière vasculaire, musculo-squelettique et neurosensoriel. De longues durées et de fortes intensités de vibration peuvent...
Associations of work activities requiring pinch or hand grip or exposure to hand-arm vibration with finger and wrist osteoarthritis
A systematic review Objective : We systematically reviewed the epidemiologic evidence linking finger and wrist osteoarthritis (OA) with work activities requiring pinch or hand grip or exposure to hand-arm vibration. Methods : PubMed and Embase databases were searched up to June 2013. We selected studies providing quantitative risk estimates of radiographic diagnosed finger and/or wrist joint OA (hand OA) in relation to work activities involving pinch or hand grip or exposure to hand-arm vibration. We used specific criteria to evaluate completeness of reporting, potential confounding, and bias....
Whole body vibration exposures in bus drivers: A comparison between a high-floor coach and a low-floor city bus
Low back pain (LBP) is common in occupational bus drivers and studies have shown a dose–response relationship between whole body vibration (WBV) exposure and LBP. Bus design may be an important factor in determining the WBV exposure a bus driver receives. The purpose of this study was to determine whether differences exist in WBV exposures between two buses commonly used in long urban commuter routes: a high-floor coach and a low-floor city bus. Each bus was driven over a standardized test route which included four road types: a newer smooth freeway, a rougher old freeway, a city street segment...
Vibration and mechanical shock exposure strongly associated with prevalence of neck pain
The objective of this study was to determine whether whole-body vibration (WBV) and mechanical shock exposure from quad bike use are associated with the prevalence of neck and low back pain (LBP) in New Zealand farmers and rural workers. Physical exposures (mechanical shocks), employee status, and low levels of workplace satisfaction are all significantly associated with the 12-month prevalence of LBP in this rural workforce that regularly uses quad bikes. Both vibration and mechanical shock exposure were strongly associated with 12-month prevalence of neck pain. The 7-day prevalence of neck pain...
Review of literature relevant in the diagnosis of HAVS
Health surveillance for those exposed to hand-arm vibration, and the diagnosis of hand-arm vibration syndrome (HAVS) is heavily dependent upon self-reporting of symptoms. However, this self-reporting may not be accurate for a number of reasons including the ability of individuals to recall symptoms, misunderstanding or misidentification of symptoms and fears regarding an individual's job, or ongoing litigation. Therefore techniques that could be used to obtain better information, or tests that could be applied to obtain a more accurate diagnosis may be useful in this area. http://www.hse.gov...
