A critical analysis of occupational therapy approaches for perceptual deficits in adults with brain injury.

Research about occupational therapy interventions for adult perceptual deficits is needed to examine the relative efficacy of different treatments and to scrutinize the theoretical assumptions underlying those treatments. The former purpose relates to providing optimal services to consumers; the latter, to advancing the knowledge base of the profession. Both of these purposes can be achieved if research questions are derived from the assumptions underlying treatments. This paper delineates those assumptions and suggests some research questions and strategies with which to test them.
