Design requirements to enhance the postural control in patients with severe spastic quadriplegia

Abstract

The aim of this project was to identify a set of design requirements that could be used as a guide to generate effective products to tackle the negative effects of severe spastic quadriplegia (SSQ) with a focus on head and trunk control. This project was undertaken with the participation of a seven year old boy with SSQ who showed an extensor pattern, according to the WeeFIM had a functional performance of 26% and was unable to control his head or trunk when subjected to anti-gravitational positions. A series of tests were conducted regarding the analysis of segmental supports. External inputs such as video, sound, vibration, and different ways to collocate clothes were evaluated as part of this study. Among the most relevant design requirements identified from this study were the recommendation about the placement of external supports on the pelvic area and avoiding physical contact with the dorsal spine.
