Abstract
In recent years, it has been observed that long-term use of hand- held tools that produce vibration may lead to disturbances in blood supply. These disturbances were detected in workers from different kinds of industry. In a specific base, metal workers showed these disturbances in the blood supply of the upper extremities after an exposure to the vibration for only 10 to 20 minutes per day. From two groups of these metal workers who did the same job with different tools, only one showed the disturbances in blood supply of the upper extremities. The only difference was seen in the range of the vibrations. Vibration of about 700 hertz led to the disturbances, whereas vibration of about 2.600 hertz did not.
