Vibration disease (VD) is one of most common among occupational diseases. It is presented in 5–18 % of total quantity of occupational diseases. It’s known that formation and character of clinical signs of vibration disease depend on many exogenous factors such as low environment temperature and local cooling of workers’ hands, significant static and dynamic load, which depends on hand mechanized tools, physical effort, and enforced working pose. Additional cooling influence increases pathogenic vibrational action and hasten development of vibrational disease. In addition, different physical characteristics of vibration can influence the character and expressiveness of organism reactions. To study special features of vibration diseases course in different occupational groups we performed comparison of clinical data in choppers, polishers, and tool-makers.
Aim. The aim of current study is to find out the features of clinical course vibrational disease in workers of different occupational groups.
Materials and methods. There have been included 107 patients with VD due to local vibration of I and II degree. Among surveyed patients there were 30.9 % of tool-makers, 46.7 % of coppers, and 22.4 % of polishers. Control group (CG) included 22 healthy volunteers. Complex examination included detailed complaints acquisition, anamnesis, studying of occupational route, and superficial examination.
For clarification and confirming of VD diagnosis we used several additional clinical-physiological methods, such as capillaroscopy of nails, electrothermometry, pallistesiometry, cold test, dynamometry with estimating of maximal wrist power and exercise tolerance of forearm muscles, and wrists and arm joints X-ray.
Discussion. During analysis of VD course in different workers we have made such outcomes. Clinical course of VD in every group had its own features. Pain syndrome was the most complicated in coppers and tool-makers, which had both functional and degenerative-dystrophic changes in upper limbs. Polishers had mainly mild course of VD with predominance of angiospasms attacks. Upper limbs polyneuropathy was predominate in tool-makers group.
