ABSTRACT
OBJECTIVES: This study examined the effects of stochastic resonance whole-body vibration training on work-related musculoskeletal symptoms and accidents. PARTICIPANTS: Participants were white and blue-collar employees of a Swiss metal manufacturer (N=38), and participation was voluntary. METHODS: The study was designed as a switching-replications longitudinal trial with randomized group allocation. The randomized controlled cross-over design consisted of two groups each given four weeks of exercise and no intervention during a second four-week period. Outcome was measured on a daily basis with questionnaires. Three components constituted musculoskeletal symptoms: musculoskeletal pain, related function limitations and musculoskeletal well-being. Accidents were assessed by ratings for balance and daily near-accidents. For statistical analysis, a mixed model was calculated. RESULTS: At the end of the training period musculoskeletal pain and related function limitation were significantly reduced, whereas musculoskeletal well-being had significantly increased. For function limitation and musculoskeletal well-being, change over time was linear. There was no effect on balance or near-accidents. CONCLUSIONS: Stochastic resonance whole-body vibration was found to be effective in the prevention of work-related musculoskeletal symptoms. It is well suited for the use in a work environment since it requires very little effort in terms of infrastructure, time and investment from participants.

79 male pupils of a metal industry school were investigated, none of whom had yet been occupationally exposed to metals or to cutting oils. In 1 or 2 years, depending on their grade and age, they would all be employees in the metal industry. Each was patch tested with nickel sulfate 5% pet., cobalt chloride 1% pet., and potassium dichromate 0.5% pet., and 28 had a positive reaction to 1 or more of the metals tested. This finding indicates the necessity not only for pre-employment patch testing in industries where contact dermatitis is likely to occur, but that patch testing should be done even earlier in school children, before they decide to enter certain occupations.
