An Investigation of Juvenile Muscle Activity for the Development of a Pediatric Prosthetic

Overview

In an age of rising conflict, there has been a significant increase in limb loss especially for the pediatric population. Yet the sustainability and cost associated with traditional prosthetic limbs remains a significant challenge, limiting the reach of such devices due to children’s rapid growth spurts. This project integrates biomedical gait analysis to create a modular growth adjustable prosthetic for transfemoral amputees. Embedded within this novel pediatric prosthetic is normal muscle activation levels for able-bodied humans while walking. This data serves as a target allowing the design to mimic the natural walking gait. Additionally this prosthetic design uses a telescope mechanism and coloured block approach to accommodate for 16cm of growth (Mduzana et al., 2020). Designed on Fusion 360, this device has achieved a weight safety score of 72 with a predicted cost of $430 demonstrating the design's viability in underprivileged and low-income nations alike.
