Brace application has been reported to be an effective approach in treating mild to moderate idiopathic adolescent scoliosis. However, little attention is focused on the biomechanical study of patient-specific brace treatment. The purpose of this study was to propose a design method of personalized brace and to analyze its biomechanical behavior and to(More)
The purpose of this study was to introduce infinite models in scoliosis and to analyze personal experience. Based on a three-dimensional patient-specific finite element model of the spine, rib cage, pelvis and abdomen, a parametric individual model of a thoracolumbosacral orthosis was built. Three standard strap tensions (20, 40, 60 N) were loaded on the(More)
An effective way to avoid invading or injuring the subjects is to use the musculoskeletal model when studying the dynamic properties of muscles in vivo. So, we put forward a joint coordinate system-based method, which mainly focuses on the coordinate's transformation of corresponding muscle attachment points, respectively, in the model and the subject in(More)
OBJECTIVE To investigate the effect of the rib cage on the vertebral axial rotation of adolescent idiopathic scoliosis under axial load condition. METHODS Three dimensional finite element model of adolescent idiopathic scoliosis included and excluded thoracic cage was built based on the data of computer tomography. The model was imported into the(More)
