Adoption of user-centred design approach in assistive product design for cerebral palsy children with mobility impairment

Cerebral palsy (CP) is the leading cause of physical disability among children, particularly affecting mobility. Despite a global decline in the number of children with CP, a significant number remains across all regions. Assistive technology (AT) is essential in improving the quality of life for children who are diagnosed with CP. Yet, existing AT solutions have not fully met the diverse demands of CP children and their families. The research aims to develop a conceptual framework using a case study methodology that integrates a user-centred design (UCD) approach and processes to pinpoint the essential factors in designing innovative mobility AT for children who suffer from CP-related mobility impairments. For this purpose, the Klang Valley region in Malaysia served as the case study for data collection. The conceptual framework was then validated through the design of a AT for children with CP. Findings reveal that children with CP commonly suffer from congenital issues, multiple associated conditions, uncertain dependence levels, and low participation rate. Wheelchairs are the most extensively studied form of AT and have evolved into multifunctional devices, yet power wheelchairs (PWs) remain underutilized. Factors influencing AT usage include the healthcare team's involvement, self-assessment, environmental considerations, and perceptions of AT. Data indicate that half of the children with CP are diagnosed before the age of one. Beyond mobility issues, they often face challenges with communication and perception. Most do not attend school, and while many do not exhibit personality disorders, the simplicity of operation and the low cost of learning are crucial for the children. Conversely, parents prioritize the ease of handling and the affordability of AT. Ultimately, a powered wheelchair (PW) was designed in accordance with the findings guided by the conceptual framework.
