Biomechanical Effects of Different Sitting Postures and Physiologic Movements on the Lumbar Spine: A Finite Element Study
This study used the finite element method(FEM) to investigate how pressure on the lumbar spine changes during dynamic movements in different postures: standing, erect sitting on a chair, slumped sitting on moen finney a chair, and sitting on the floor.Three load modes (flexion, lateral bending, and axial rotation) were applied to the FEM, simulatin
