  1. Assessment of hand-arm vibration exposure among traffic police motorcyclists.

    Article - En anglais

    The aims of this study were (1) to evaluate subjective symptoms in the hand-arm system of all traffic police motorcyclists of a city located in the central part of Japan and (2) to assess their hand-arm vibration exposure associated with traffic police motorcycle riding.

    The study population consisted of 119 motorcycling traffic policemen and 49 male controls.

    By means of a questionnaire, information on the occupational history and the presence of subjective symptoms in the hand-arm system of all subjects was obtained.

    Vibration was measured on the handlebars of the representative motorcycles and on the hands of the riders.

    The 4-and 8-h energy-equivalent frequency-weighted acceleration as well as the lifetime vibration dose were calculated for all police motorcyclists.

    The prevalence of finger blanching in the traffic police motorcyclists was 4.2%, but none of the controls had this symptom.

    The rates of finger numbness (19.3%), finger stiffness (16.0%), shoulder pain (13.4%), and shoulder stiffness (45.4%) were significantly higher among police motorcyclists as compared with controls.

    The root-mean-square (rms) frequency-weighted acceleration on the handlebars of police motorcycles was in the range of 2.2-4.9 m/s2 rms.

    The computed 4-and 8-h energy-equivalent frequency-weighted acceleration values were 2.8-4.5 and 2.0 - 3.2 m/s2 rms, respectively.

    A pattern of increasing percentage prevalence with increasing cumulative vibration dose was noticed. (...)
