“…Our findings are consistent with the results reported in other studies (6,7,21,22) which found impairment to manual dexterity in groups of workers exposed to hand transmitted vibration. However, our findings could not be directly compared with these results as most of the published studies deal with developed HAVS cases (6,7,31), rarely discussing the biological processes of damage/repair that are relevant for the The decreased grip strength has also been reported (6,8,9).…”

A frequently encountered exposure profile for hand-arm vibration in contemporary occupational setting comprises workers with a long history of intermittent exposure but without detectable signs of hand-arm vibration syndrome (HAVS). Yet, most of the published studies deal with developed HAVS cases, rarely discussing the biological processes that may be involved in degradation of manual dexterity and grip strength when it can be most beneficial -during the asymptomatic stage. In the present paper, a group of 31 male asymptomatic vibration-exposed workers (according to the Stockholm Workshop Scale) were compared against 30 male controls. They were tested using dynamometry and dexterimetry (modelling coarse and fine manual performance respectively) and cold provocation was done to detect possible differences in manual performance drop on these tests. The results showed reduced manual dexterity but no significant degradation in hand grip strength in the exposed subjects. This suggests that intermittent exposure profile and small cumulative vibration dose could only lead to a measurable deficit in manual dexterity but not hand grip strength even at non-negligible A(8) levels and long term exposures.

“…As high as 36% of the high exposure group had abnormal Purdue Pegboard test that was used to measure dexterity as compared to only about 14% in the low‐moderate group. This finding is validated by a prospective cohort study among workers exposed to HAV which reported that the Purdue Pegboard score was lower as the HAV exposure level increases during the 1‐year follow‐up . Moreover, the same study also reported that the deterioration of the score over time was associated with worsening of the hand functions in the workers.…”

Background Prolonged exposure to hand‐arm vibration is associated with a disorder of the vascular, neurological, and musculoskeletal systems of the upper limb known as hand‐arm vibration syndrome (HAVS). Currently, the evidence of HAVS in tropical environments is limited. Objectives To determine the prevalence and severity of HAVS among tyre shop workers in Kelantan, Malaysia. Methods A cross‐sectional study involving 200 tyre shop workers from two districts in Kelantan was performed. Part one data were collected at the field using questionnaire, and hand‐arm vibration was measured. Part two involved a set of hand clinical examinations. The workers were divided into high (≥5 m s‐2) and low/moderate (<5 m s‐2) exposure group according to their 8‐hr time weighted average [A(8)] of vibration exposure. The differences between the two exposure group were then compared. Results The prevalence of the vascular, neurological, and musculoskeletal symptoms was 12.5% (95% CI 10.16 to 14.84), 37.0% (95% CI 30.31 to 43.69), and 44.5% (95% CI 37.61 to 51.38) respectively. When divided according to their exposure statuses, there was a significant difference in the prevalence of HAVS for all three components of vascular, neurological, and musculoskeletal (22.68% vs 2.91%, 62.89% vs 12.62% and 50.52% and 38.83%) respectively. All the clinical examinations findings also significantly differed between the two groups with the high exposure group having a higher abnormal result. Conclusion Exposure to high A(8) of vibration exposure was associated with a higher prevalence of all three component of HAVS. There is a need for better control of vibration exposure in Malaysia.

“…Symptoms for musculoskeletal disorders in HAVS usually manifest as ache, pain, stiffness and loss of strength in the fingers, hand, wrist or arm; upper limb tendinitis and osteoarthrosis are common among vibration-exposed workers 3 , 4 , 5 ) . In the later stages, impairments of hand functions like reduced strength and manipulative dexterity may be potentially disabling, and may interfere with work, social and domestic activities 6 ) .…”

A systematic review of diagnostic performance of quantitative tests to assess musculoskeletal disorders in hand-arm vibration syndrome

et al. 2015

The purpose was to systematically review the published reports for the clinical utility of quantitative objective tests commonly used for diagnosing musculoskeletal disorders in hand-arm vibration syndrome (HAVS). Two reviewers independently conducted a computerized literature search in PubMed and Scopus using predefined criteria, and relevant papers were identified. The articles were screened in several stages and considered for final inclusion. Quality of the selected papers was evaluated by a modified QUADAS tool. Relevant data were extracted as necessary. For this review, only 4 relevant studies could be identified for detailed examination. Grip strength, pinch strength, and Purdue pegboard tests were commonly used with their reported sensitivity and specificity ranging between 1.7 to 65.7% and 65.2 to 100%, 1.7 to 40% and 94 to 100%, and 44.8 to 85% and 78 to 95%, respectively. A considerable difference across the studies was observed with respect to patient and control populations, diagnostic performance and cut-off values of different tests. Overall, currently available English-language limited literature do not provide enough evidence in favour of the application of grip strength and pinch strength tests for diagnosing musculoskeletal injuries in HAVS; Purdue pegboard test seems to have some diagnostic value in evaluating impaired dexterity in HAVS.
