五禽戏虎举对青少年特发性颈椎后凸干预作用的有限元分析
Finite element analysis of intervention effect of Wuqinxi(五禽戏)Huju(虎举)on adolescent idiopathic cervical kyphosis
摘要
Abstract
Objective To explore the changes of stress and displacement of intervertebral discs and vertebral bodies in adolescent idiopathic cervical kyphosis models caused by Wuqinxi(五禽戏)Huju(虎举)and extension movement after torque loading by finite element analysis.Methods One healthy male volunteer aged 24-year-old(heighted 178 cm and weighted 65 kg)was selected,software such as Mimics 21.0,Geomagic wrap 2017,SolidWorks 2017,and Ansys Workbench 17.0 were used to simulate adolescent idiopathic cervical spine model,an axial compressive load of 266 N was applied to the center of the end plate on C2 for head physical gravity simulation,the lower part of C7 vertebral body was set as the point of free-dom constraint,a torque of 1.5 N·m was applied with C2 as the reference point to simulate the stress on intervertebral discs and vertebral bodies after 45° movement of Wuqinxi(五禽戏)Huju(虎举).Results The normal C2-C7 cervical spine model and adolescent idiopathic cervical kyphosis model were successfully constructed.The maximum stress value of intervertebral disc when the Huju(虎举)was raised and extended at 45° and loaded with torque occurred in C3,4 intervertebral disc(3.588 1)MPa.The maximum stress values of each intervertebral disc were C3,4(3.588 1 MPa)>C2,3(3.467 5 MPa)>C4,5(2.597 7 MPa)>C5,6(2.378 8 MPa)>C6,7(1.404 9 MPa),respectively.The maximum stress of C6 vertebral body was 5.842 9 MPa,while the stress-es of C2,C3,C4,and C5 vertebral bodies was 4.184 8,4.437 8,4.148 7,and 2.852 4 MPa respectively.The overall stress of ver-tebral body was mainly concentrated in the front of vertebral body.Conclusion After long-term practice of Huju(虎举)move-ment,the stress concentration in intervertebral discs and the front of vertebral body changes the stress load state of interverte-bral discs and vertebral body.As time goes by,intervertebral discs may change,forming a shape that is higher in the front and lower in the back.The vertebral body may also undergo remodeling,resulting in a relative increase in the height of the anterior edge of vertebral body and promoting the recovery of cervical kyphosis to a physiological lordosis state.关键词
