CUSTOM ADAPTATION PURPOSE: To provide proper positioning for a child with multiple disabilities, including cerebral palsy and lung disease. The family owned a Medifab seat and insert that was used in the car and provided appropriate positioning and support. However, they found it inconvenient to transfer the seat from the car to the house each time it was needed. The solution was to create another shell for the seat insert using an existing Medifab mobile base frame that was not being used. The seat insert was measured and a plywood shell and footrest were made to fit. The next step was to determine how to fit the new shell in the frame. The frame has adjustable legs with casters at the bottom, and a plate at each side with multiple holes in arcs that had enabled the original seat to be tilted. A metal frame was added to the seat shell, along with two fixed pins at the front corners and two spring-loaded retractable pins at the back corners. The front pins fit into the grooves at the front of the side plates on the base frame. The back pins fit into the arc of holes at the back of the side plates. The spring-loaded pins are attached to handles that are squeezed to retract the pins to tilt the seat to the desired angle. A piece of bent steel was then attached to the bottom of the shell to mount the footrest. The steel has a series of holes which enable the footrest to be adjusted down to accommodate future growth. Attachments are also mounted on each side of the shell to accommodate an existing tray, which can be adjusted backwards and forwards using different holes in the shell. With the shell completed, it was possible to unclip the insert from the seat in the car, position it in the indoor shell and base, and place the removable tray in position, creating a high chair that can be used for eating and other activities. DIMENSIONS: The footrest can be adjusted 120 millimeters down in 20 millimeter increments. TITLE: All in the Family. JOURNAL: TAD Journal. REF: Volume 25, Number 4, Summer 2005. PAGES: 12-14.
