Design of a multifunctional specialized wheelchair mechanism for cerebral palsy in children.

ABSTRACT

This paper describes and evaluates an approximation of the proposed position-changing mechanism of a cerebral palsy wheelchair for children using only one actuator. Only details the functional requirements that allow the change of position wheelchair mode, standing frame mode, and stretcher mode. To evaluate the mechanism, a video was recorded and evaluated in Kinovea, and MATLAB software to obtain the functional angular range of the backrest reclination and the seat elevation. The scaled prototype has a mean error of 2.58% in comparison with the original design. The results indicate that this mechanism effectively provided compliance with the proposed angles and comfort for the patient.
