Effect of seat inclination on intradiscal pressure during simulated driving task, assessed using a biomechanical model

This work aimed to develop a mathematical model to evaluate the effect of seat inclination using as input the biomechanical characteristics of the user. The biomechanical model includes weight, posture, flexion of the pelvis and trunk and 5° and -5° seat inclinations. Using actual data collected dur...

Using actual data collected during an experiment with 26 participants, a validation process was carried out to measure the model's ability to correctly predict load values on the ischial tuberosity.
