1. The severity of hand-arm vibration syndrome (HAVS) is classified according to the Stockholm Workshop scale, which is divided into stages of sensorineural and vascular symptoms 2. Standardised tests have a specific role in distinguishing early and late stage 2sn HAVS and should not be used as an alternative to clinical diagnosis 3. The Griffin scale indicates extent of colour changes, and should be supplemented by a diagrammatic record 4. The Lawson modification of the Stockholm Workshop scale should be used to determine advice to the affected employee 5. The vascular component of HAVS produces functional disability during an attack of Raynaud's phenomenon, and therefore requires avoidance of cold exposure 6. Persistent functional impairment, which is independent of temperature, reflects sensorineural disease 7. Removal from exposure, especially at an early stage of the condition, may result in regression of symptoms 8. There is limited scope for pharmacological treatment of established HAVS.
