Abstract
Purpose:
Purpose of this study is to explore the interdependence of eccentric force, torque, joint angle, and angular velocity during human multi‑joint leg extension.
Design/Methodology/Approach:
Joints will be identified for calculation of various forces. Analysis of the forces will be then carried out in software for dynamic conditions. The materials usually used for joints are usually methyl methacrylate (MMA)–poly (methyl methacrylate) (PMMA) and ultra-high molecular weight polyethylene (UHMWPE).
Findings:
The results show that force/torque production during multi-joint leg extension in humans depends on both joint angle and angular velocity. This result should be accounted for in-modeling and optimization of human joint movement. The results from the analysis will be used for deciding which material to be used for joints and how to design the artificial joints based on result of analysis. The analysis can be used for further research of joints made up of biomaterials.
Research limitations/implications:
The research is limited due to lack of proper data. So far, very less research has been done on the mathematical aspect of biomaterials. This study will help in further analysis of biomaterials.
Practical implications:
This study will help us in deciding the proper materials that can be used in joint replacements while having enough strength to be viable for mass usage. In addition, this study can be used to create prototype models of joints based on the analysis done in this study.
Social implications:
This study will be used to make joints for joint replacement surgeries. The study will enable people to have these replacements economically while being strong enough to be used in daily life.
Originality/value:
Not many people have researched on the mechanical aspects of biomaterials, which is seen by the lack of experimental data available. This study allows us to use the analysis in further study of joints made up of biomaterials.
