title: Traumatic brain injury: classification of initial severity and determination of functional outcome.
abstract: OBJECTIVE
  The aim of the present manuscript is to review current methods for classifying initial severity and final outcome in traumatic brain injury (TBI) and to suggest a direction and form of further research.
  
  
  METHODS
  The literature on valid and reliable measurements used in TBI-research for classifying initial severity and final outcome was reviewed.
  
  
  RESULTS
  Classifying initial severity in patients with head injury according to clinical condition or CT-parameters is valid. Classifying outcome according to measurement tools of disability showed adequate validity and reliability.
  
  
  CONCLUSIONS
  Future research in TBI outcome, particularly in rehabilitation medicine, should focus on determinants of outcome, identifying those patients who will have the greatest chance of benefiting from intensive rehabilitation programmes. More research is needed to determine the long-term functional outcome in TBI, the long-term socio-economic costs, and the influence of behavioural problems on family cohesion. Finally, validation of outcome measures is required in the TBI-population; the relative value of various outcome measures needs to be determined, and the usefulness and applicability of measures for health related quality of life in TBI should be established.
