AbstractDESCRIPTION (provided by applicant): We have designed a prototype lightweight, sturdy, user adjustable ergonomically designed backrest support for ultralight weight wheelchairs that will provide necessary postural support and provide a variety of position s to ease dressing, propulsion, and seated comfort. The backrest will improve user comfort, function, and posture during multiple activities of daily living. The innovative design will enable the user to adjust the backrest position while seated in their w heelchair. The benefits of the design are lightweight, high strength, adjustability and durability. The backrest will be adaptable to most ultralight manual wheelchairs. The backrest will be designed with a battery of features that benefit the user includi ng height selection, backrest angle adjustment, backrest to axle positioning, and lumber support. The purpose of the proposed research is to create and test prototypes to identify issues that need to be addressed to develop a practical commercial device. T he prototypes will be tested to insure that 1) its dimensions fit a wide variety of ultralight wheelchairs, 2) it meets of exceeds currently approved ANSI/RESNA wheelchair and seating standards, and 3) it performs equivalently of better than other comparab le manual wheelchair backrests on ANSI/RESNA tests. A consumer and clinician focus group will evaluate the prototype models and their feedback will be incorporated into the design to be tested to the ANSI/RESNA standards. There are a wide variety rigid bac krests commercially available; however, most are heavy, unappealing, and apt to fail under active use. Currently, there are no commercially available backrests that have the capability of being adjusted by the user while seated in the wheelchair. The innov ative design of the Lightweight, Durable, and Adjustable Composite Backrest will provide necessary postural support and provide the user a variety of self adjustable positions to promote independence with dressing tasks and propulsion, while providing seat ed comfort during work tasks in a variety of environmental settings. The backrest will improve user comfort, function, and posture during multiple activities of daily living.
