Independent Wheelchair Transfers in the Built Environment: How Transfer Setup Impacts Performance Phase 2: Final Report

Seat width and depth: ADA-ABA currently requires a minimum entry point of 24 inches for transfer steps in play (Section 1008.3.1.1) [7] and pool areas (Section 1009.4.5) [7].  Additionally a 30 inch minimum width has been proposed medical diagnostic exam tables.  We selected 18 inches minimum seat width as a starting point with the potential to grow to 30 inches.  The seat depth was not a primary variable of interest and was fixed at 16 inches.  This dimension is within the range of seat depths allowed for transfer steps in play and pool areas and for proposed diagnostic equipment (14 to 17 inches).  Transfer surfaces on the station were padded with 1" foam and a vinyl cover for comfort and to protect the skin during the experimental protocol.
