The author submits the hitherto assembled results of the longitudinal study of a group of 121 men – former miners who were transferred in 1988 from the risk of suprathreshold vibrations on account of occupational disease – diseases of the nerves and blood vessels of the upper extremities. The investigated group was re-examined in 1993 and 1998 after five-years intervals. The next examination is planned for 2003. The results suggest a spontaneous regression of original pathological findings of traumatic vasoneurosis in the vasospastic stage and in milder and medium severe motor lesions in the area of the distal portion of the median nerve after elimination from the risk of suprathreshold vibrations.
