Anthropometry-Based Human-Centered Design and Material Engineering of a Walking Aid for Children With Cerebral Palsy

Abstract

Cerebral palsy (CP) is a neurological disorder characterized by impaired movement, balance difficulties, abnormal muscle tone, and motor dysfunction resulting from brain damage during early developmental stages of birth. These impairments significantly influence a child’s ability to perform daily activities and lead an independent life. Therefore, providing appropriate assistive mobility devices is essential to enhance mobility, safety, and overall quality of life for children with CP. Walking aids are commonly used rehabilitation devices designed to support movement and promote independence. Many existing walking aids are not designed using anthropometric data representative of the geographical population for which they are intended, which may reduce their ergonomic suitability. This study addresses this limitation by developing a local anthropometric database for Jordanian children with CP aged 1–5 years. Anthropometric measurements were collected and analyzed to support ergonomic design requirements. Based on these measurements, dimensional requirements were established and translated into a conceptual computer-aided design (CAD) of an adjustable walking aid. The proposed conceptual design incorporates appropriate dimensional specifications derived from the collected anthropometric data to ensure comfort, stability, and safety. Jansen mechanism of motion is applied to the new design to promote children mobility. The proposed walking aid is intended to accommodate children with CP within the 1–5-year age group, facilitating improved mobility and supporting their participation in daily activities and rehabilitation programs.
