In connection with medical appraisements of the occupational disease No. 2104 "Vibration-induced vasospastic disease" 240 patients could be examined a first time, 94 of them a second time, 42 patients a third time and 11 patients a forth time. The interval between examinations was 2, 4 or 6 years respectively. The standard procedure besides clinical whole body examination included anamnestic questionnaire, cold-provocation test with infrared thermography and vibrotactile perception test. The evaluation of the diagnoses in principle followed the Stockholm vascular V and sensorineural SN stages and was used to establish the grade of disability for compensation. The re-examinations after 2-6 years gave information on the development of the health status after cessation of vibration exposure. In only about 54% of all cases there was any improvement, in 39% the health status was unchanged, in 7% aggravated. It is obvious that the reversibility of the VWF if any needs many years abstaining from vibration exposure.
