Impact of wheeled seated mobility devices on adult users' and their caregivers' occupational performance: a critical literature review.

The prescription of wheeled seated mobility devices for clients with mobility impairment is a growing area in occupational therapy practice. The goal is to enhance client participation in occupation through technical intervention. This critical review examines the body of knowledge concerning the impact and effectiveness of the provision of wheeled seated mobility on the occupational performance of wheelchair users and their caregivers. The scope and gaps in the literature are defined to identify areas for future research. While the focus is on the methodological issues of the research reports, the relevance of findings to occupational therapy practice will also be reviewed. The results of the 46 studies in this review indicate that the majority of research conducted thus far have methodological limitations, which limits the extent to which this body of research can be drawn upon to provide evidence for the effectiveness of wheeled mobility systems. While most of the studies reviewed addressed constructs of relevance to occupational therapy practice, there was an emphasis on performance components and inadequate attention to engagement in occupations. This review is an important first step in building the ability of occupational therapists to demonstrate effectiveness in wheeled seating interventions.
