Estimation and Validation of Body Segment Parameters Using 3D Geometric Model of Human Body for Female Workers of Central India

Abstract

Body segment parameters are required as input parameters to analyze the forces and moments acting on the joints. They can be used to design the farm tools, protective clothing, equipment, and workplaces. The study was planned to develop geometric models for female agricultural workers of Central India. Anthropometric data of 180 female agricultural workers aged between 25 and 45 years having weight of 45.74 ± (7.56) kg and height of 1510 ± (50) mm were collected to develop 14-segmental 3D geometrical models. The values of mean, maximum, minimum, standard deviation (SD) and 5th and 95th percentile anthropometric dimension were calculated. Based on geometric models, mass, density, volume, center of mass (COM) and moments of inertia of body segments were calculated. To test the validity of the model with other models for body segment parameters, an analysis was carried out using SAS 9.3 software with one-way analysis of variance. There was a significant difference (p \ 0.01) between the study model and other models based on Dunnett’s multiple comparisons post hoc test. From post hoc test analysis, it was observed that developed 14 segments geometric model can be used to determine body segment parameters (BSPs), i.e., segment mass, volume, center of mass (COM) and radius of gyration (RG).
