Raynaud's phenomenon of fingers and toes of miners exposed to local and whole-body vibration and cold.
In a study of 27 underground miners exposed to hand or whole-body vibration, cold or other vasoconstrictive environmental factors, higher prevalences of Raynaud's phenomenon in both fingers and toes were found than in a control group not exposed to vibration. There were no Raynaud-like phenomena among miners not exposed to vibration. There was a positive correlation between the two locations. This may mean a general susceptibility of vasospasm, but it seems more probable that the disorders are caused by vibration exposure to fingers and toes.
