Return to work after head injury: a review of post-war studies.

The literature on occupational resettlement after head injury is confounded by varying standards of clinical severity and social outcome. A comparison of eleven key studies in the light of the authors' own research yielded a success rate ranging from 50 to 99 per cent, but this was based on superficial evidence. A more searching enquiry is needed, using objective methods and avoiding the technical inadequacies of most previous work. This would be unlikely to challenge the importance of age and length of post-traumatic amnesia as determinants of return to work, but should lead to a better understanding of other factors such as previous occupational status, cognitive deficits and personality changes.
