Abstract
A total of 824 chain-saw operators who were employed in felling trees in the forestry industry were exposed to local vibration, which produced peripheral blood-flow disorders and lesions in the joints and hand bones. In the last 10 years, they have undergone 24-day balneoclimatic treatment at the Kołobrzeg Health Resort. It was found that a stay in the spa and certain balneological treatments exert a favorable effect on the peripheral blood-flow disorders produced by the local vibration of chain saws. The symptoms (chills and numbing of the fingers, etc.) disappeared in nearly 40% of these workers. An improvement in the objective indices of the peripheral circulation (thermographic and plethysmographic tests) was observed in about 90% of patients treated with brine baths combined with underwater vibratory massage (rotatory) or brine baths alone. The brine bath and vibratory massage have a direct beneficial influence on the peripheral blood flow of pectoral limbs.
