“…Our findings of Bovenzi et al an increased risk for reduced work ability in the HTVexposed workers may be of help for the implementation of further studies aimed at investigating the impairment to work capacity caused by long-term exposure to vibration (25). These adverse effects, however, may not be attributed only to vibration since working with vibratory tools entails also exposure to ergonomic risk factors such as hand/forearm physical overload which was associated with sensory symptoms, interference with work activities and limited work performance in this study.…”

“…Other explanations such as additional effects from psychological mechanisms may also be plausible (16). It is further possible that workers with high exposure are more aware of signals and symptoms from their hands because they know that vibrations are potentially harmful.…”

A prospective cohort study investigating an exposure-response relationship among vibration-exposed male workers with numbness of the hands by Edlund M, Burström L, Gerhardsson L, Lundström R, Nilsson T, Sandén H, Hagberg M This study on hand-arm-vibration (HAV) exposed workers spanned 16 years; exposure dose was assessed for each individual; and the study may contribute to knowledge about an exposure-response relationship between neurological symptoms and HAV exposure. Furthermore, to our knowledge, there are no other studies reporting incidence of numbness in hands among HAV-exposed workers or how it affects work performance. Affiliation 203Original article Scand J Work Environ Health. 2014;40(2):203-209. doi:10.5271/sjweh.3386 A prospective cohort study investigating an exposure-response relationship among vibration-exposed male workers with numbness of the hands Objective The aim of this study was to investigate the exposure-response relationship of hand-arm vibration (HAV) exposure to neurological symptoms (numbness) of the hand in a cohort of vibration-exposed workers. MethodsThe baseline cohort comprised 241 office and manual workers with and without exposure to HAV.Numbness (the symptom or event) in the hand was assessed for all subjects at baseline and follow-ups after 5, 10, and 16 years. The workers were stratified into quartiles with no exposure in the first quartile and increasing intensity of exposure in quartiles 2-4 (groups 1-3). Data analysis was performed using survival analysis (time-to-event). Information on cumulative exposure and years of exposure to event was collected via questionnaires. Measurements were performed in accordance with the International Organization for Standardization (ISO) 5349-1. ResultsThe hazard ratio (HR) of risk of event (numbness) differed statistically significantly between the nonexposed group (group 0) and the two higher exposure groups (groups 2 and 3). There was also a significant ratio difference between the lowest exposure group (group 1) and the two higher groups. The ratio for group 1 was 1.77 [95% confidence interval (95% CI) 0.96-3.26] compared with 3.78 (95% CI 2.15-6.62) and 5.31 (95% CI 3.06-9.20) for groups 2 and 3, respectively. ConclusionThe results suggest a dose-response relationship between vibration exposure and numbness of the hands. This underlines the importance of keeping vibration levels low to prevent neurological injury to the hands.

“…Other factors must also be considered however. In a previous study, we found that psychological status, assessed by the Hospital and Anxiety Depression Scale, had a considerable impact on work ability [ 9 ]. Thus a multidimensional approach, including psychological factors, is needed when studying work ability in vibration-exposed workers.…”

“…In a previous investigation, the influence of psychological status on work ability in vibration-exposed workers was studied, using the Hospital Anxiety and Depression Scale [ 9 ]. This study of vibration-exposed workers with varying stages of vibration-induced neuropathy aimed to investigate the impact of factors that may affect work ability, e.g.…”

BackgroundHand–arm vibration exposure may cause hand–arm vibration syndrome (HAVS) including sensorineural disturbances.AimsTo investigate which factors had the strongest impact on work ability in vibration-exposed workers.MethodsA cross-sectional study in which vibration-exposed workers referred to a department of occupational and environmental medicine were compared with a randomized sample of unexposed subjects from the general population of the city of Gothenburg. All participants underwent a structured interview, answered several questionnaires and had a physical examination including measurements of hand and finger muscle strength and vibrotactile and thermal perception thresholds.ResultsThe vibration-exposed group (47 subjects) showed significantly reduced sensitivity to cold and warmth in digit 2 bilaterally (P < 0.01) and in digit 5 in the left hand (P < 0.05) and to warmth in digit 5 in the right hand (P < 0.01), compared with the 18 referents. Similarly, tactilometry showed significantly raised vibration perception thresholds among the workers (P < 0.05). A strong relationship was found for the following multiple regression model: estimated work ability = 11.4 − 0.1 × age − 2.3 × current stress level − 2.5 × current pain in hands/arms (multiple r = 0.68; P < 0.001).ConclusionsVibration-exposed workers showed raised vibrotactile and thermal perception thresholds, compared with unexposed referents. Multiple regression analysis indicated that stress disorders and muscle pain in hands/arms must also be considered when evaluating work ability among subjects with HAVS.
