Modification of the Stockholm Vascular Scale

摘要

Background Staging hand–arm vibration syndrome (HAVS) depends upon accurate reporting of the extent and frequency of blanching attacks. Reporting may not be repeatable and not all individuals classifiable using the Stockholm Workshop Scale (SWS). For Department of Trade and Industry (Dti) coal miners' assessments, the SWS was modified to include a blanching score. Further modifications, which involve splitting Stage 2V into ‘early’ and ‘late’ have been proposed but the impact of this on classification has not been investigated.
