Vibration and Its Effects on the Body

Abstract

Objectives: To assess the effects of machine-induced vibration on workers and to determine effective precautions for vibration-induced trauma. Subjects and Methods: The study group consisted of 114 workers who were randomly selected: 50 rock drill workers and 64 truck heavy vehicle operators. Fifty-four office workers were designed as controls. The study and control groups were age-matched. All subjects were interviewed to determine subjective symptoms using a 38-item questionnaire designed by the Medical Committee of Vibration Disease, Japanese Association of Industrial Health. Results: The complaints of pain in the fingers, sensitivity to cold, numbness and pain of fingers at night, weakness of static position, wrist-elbow pain, difficulty in bending and stretching elbow, pain in shoulder when holding up arms, lower back pain, sleeping disturbance and hearing difficulty were significantly higher in rock drillers than heavy vehicle operators and office workers (p < 0.05–0.01). Conclusion: Permanent vibration exposures cause negative physical effects that may lead to occupational diseases. In order to be protected against whole-body and hand-arm vibrations, technical and medical measures must be taken into account.

Mechanisms Mediating Vibration-Induced Chronic Musculoskeletal Pain Analyzed in the Rat

“…Occupational exposure to vibration, which frequently produces musculoskeletal pain, and arm, shoulder and hand disabilities 32, is a significant public health problem 11, 15, 16, 26, 33, 41, 47, 51, 71. In an attempt to determine the underlying mechanism(s), several animal models have been developed.…”

Evaluation of Exposure to Whole-Body Vibration and its Health Effects on Train Operators in Tehran-Andimeshk Line, Iran

“…To study the health effects of whole-body vibration and to assess the relationship between these effects and age, job history and number of the trips in the TehranAndimeshk train, questionnaires were written see references [1, [9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24]. Then they were filled out during the trips by the operators.…”

Train Passengers Comfort with Regard to Whole-Body Vibration

“…To study the health effects of whole-body vibration and assessment of the relationship between these effects and age, gender and number of the trips on the Tehran-Andimeshk train, questionnaires were prepared using literature and consulting specialists, see references [2,[8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23]. These were completed during the trips by the passengers.…”
