Definition - What does Segmental Vibration mean?
Segmental vibration refers to a medical condition that affects a section of the body, in particular the hands and arms from being exposed to repetitive vibratory sensations such as caused from handling mechanical equipment that generates rough oscillatory sensation. Certain trades require manipulation of such powered tools that produce vibratory action including chainsaws, jackhammers, and even sewing machines, which can potentially disrupt sensory motor feedback in the hands and arms resulting in insensitivity to touch or white finger disease.
WorkplaceTesting explains Segmental Vibration
Segmental vibration relates to a physical condition affecting parts of the body, usually the hands and arms, involving repeated exposure to, and manipulation of, mechanical equipment that produces oscillatory force against sensory nerves and capillary vessels. This can lead to potential circulatory and neurological damage. Manual labor positions often employ powered tools incorporating pneumatic or vibratory pressure as its primary function during use such as drills and chainsaws, which can, in effect, impose detrimental conditions to the hands and arms exposed to jarring sensations over an extended length of time. The resulting damage can include insensitivity to touch, Raynaud’s phenomenon, also referred to as hand-arm vibration syndrome, and white finger disease, which affects blood vessel circulation aggravated by cold exposure.
