Vibration disease

VIBRATION DISEASE (EN: vibrating sickness; DE: Erschutterungskrankheit; FR: maladie de bibration; ES: enfermedad producida por la vibracion; RU: вибрационная болезнь) is the occupational disease, which is determined by the prolonged impact of the vibrations; this desease is caused by the local vibration, which is impacting the limited place of the body (for example, during the work with the hand-held pneumatic and electric hammers), and by the general vibration, which is influencing the entire organism (for example, at the transport). The times of the development, and the expressiveness of the disease, depend on the spectral characteristics of the vibrations, on the accompanying production factors (the cooling, noise, compelled position of the body, and others), and on the individual sensitivity of the organism.

The main mechanisms for the development of the vibration disease are: the emergence of the adverse reflexive reactions of the organism as the response to the irritating action of the vibrations onto the receptors of the skin, and of the neuro-vascular, muscular, and skeletal systems. The major manifestations are: the change of the vascular tone, of the exchange within the neuro-muscular and skeletal systems, the decreasing of the blood supply to the tissues, the disruption of the regulation of the cardio-vascular and nervous systems.

The characteristic complaints are: the chillness and numbness of the hands, the whitening of the fingers (especially after the cooling), the pains, less often the weakness of the arms, the disruption of the sensitivity; often the fatiguability, blurred headaches, increased irritability, and disturbance of the sleep. During the action of the general vibrations, there are involved into the process the vessels of the legs, there occur more often the headaches, dizziness, and pains within the heart. They distinguish several stages of the vibration disease. Under the conditions of the modern production, there may prevalently be found the initial stage of the vibration disease. During this period, the working ability of the sick persons usually does not decrease. The working ability and the prophylactic suitability of the patients with the vibration disease are determined by the medical commission.

The prophylactic against the vibration disease may be ensured through the compliance with the sanitary requirements to the tools and equipment, which are hazardous because of the vibration, through the usage of the vibration damping devices (appliances), through the hygienic rationing for the levels of the vibration, through the compliance with the optimal schedule for the work and recreation; there have the substantial significance the correct prophylactic selection, the periodic medical examinations, and so on. During the treatment of the vibration disease, there are effective the medications and physical methods for the therapy, which are improving the supply of the blood, and the exchange processes within the neuro-muscular system. There are advised the antispasmodics, vitamins of the B group, ganglioplegic, therapeutic gymnastics, massage, thermal procedures, hydrogen sulfide and radon baths, and so on.
