Análisis de parámetros antropométricos en modelos musculoesqueléticos del cuello-cabeza : análisis de parámetros de esfuerzos internos en un modelo musculoesquelético del cuello-cabeza en accidentes de vehículo.

Abstract

In this research, anthropometric parameters are analyzed in musculoskeletal models of the neck-head system. The study uses photogrammetry and electromyography (EMG) to measure muscular activity in a simulated vehicular accident scenario. Markers and EMG sensors are placed on selected muscles to collect data. Two methods are employed for analysis: programmed calculations and simulation using the OpenSim software. The muscular activity data obtained is compared with functional patterns from natural flexion-extension movements to evaluate differences. The study further compares curves derived from each movement type—the accident scenario and the flexion-extension movement—to assess biomechanical responses. For reliability, multiple correlation coefficients (CMC), standard error of measurement (SEM), and intraclass correlation coefficient (ICC) are determined. Additionally, an ANOVA significance analysis is conducted to quantify the risk level associated with the simulated accident movement. Finally, the findings are validated through these coefficients, establishing the risk level involved in performing the simulated accident movement on the test subjects.
