Effects Of Yoga Exercise On Trunk Morphology And Pulmonary Function Of College Students With Idiopathic Scoliosis

Scoliosis is a morphologic lesion of the spine,the cause of which is unknown.Scoliosis can result in limited movement range of the spine,atrophy and weakness of the muscles near the spine,accompanied by a certain degree of respiratory dysfunction.As its cause IS unknown,it IS clinically known as Idiopathic Scoliosis.Eighty percent of patients with Scoliosis are in their Adolescent stage of disease,which is medically known as the Adolescent Idiopathic Scoliosis.In recent years,various reports show that there are more patients with scoliosis in college students.Abnormal spinal curvature causes abnormal body posture,which has a serious negative impact on their physical and mental health.Therefore,rehabilitation intervention for AIS patients is of great importance to the development of adolescent patients.Objective: To explore the effect of yoga on the trunk shape and lung function of AIS patients through 12 weeks of yoga.Specifically,the intervention effect of yoga on trunk morphological indicators of AIS patients included: COBB Angle,clavicular Angle(CA),pelvic Angle(PO),sacral Angle(SO).The effect of yoga exercise on the pulmonary function indicators of AIS patients,related test indicators include: vital capacity(VC),forced expiratory volume in one second(FEV1.0),temporal vital capacity(FVC)and the percentage of forced vital capacity in one second(FEV1.0/FVC%).Methods: In this study,16 male college students with AIS were selected as subjects.The subjects were randomly divided into two groups: an experimental group(n=8)and a control group(n=8).During the 12-week period,the experimental group received a yoga exercise intervention three times a week,while the control group received no intervention of any kind.Independent sample T test was used to analyze the difference between the morphological index and lung function index before and after intervention.Paired T test was used to analyze the difference between the morphological index and lung function index of the control group and the experimental group before and after the experiment.Results: 1)Before and after the experiment,the morphological indicators of Cobb Angle,CA,PO and SO in thoracic and lumbar segments were significantly different in the experimental group(P<0.01).There were significant differences in lung function indexes such as FVC,FEV1.0 and FEV1.0/FVC%(P<0.01).2)before and after the experiment,there were significant differences between the experimental group and the control group in the morphological indicators such as Cobb Angle and SO(P<0.01),while there were significant differences between CA and PO(P>0.05).There were significant differences in FEV1.0(P<0.05),but no significant differences in VC,FVC and FEV1/FVC(P>0.05).Conclusion:(1)Yoga can effectively improve the condition of AIS patients,specifically,the key indicator Cobb Angle is significantly improved.Other poor posture,such as coronal high and low shoulder,tilt of the pelvis,trunk deviation and other obvious improvement.In sagittal plane,the posture of pelvis forward and spine backward was improved significantly,while the change of thoracolumbar curvature was less.In general,the rehabilitation effect of AIS patients with coronary deformity is better than that of the sagittal plane.(2)Yoga's release of plantar fascia,activation of correct plantar line,pelvic orthostatic,diagonal training and thoracic rotation training can effectively improve the shoulder imbalance,pelvic tilt,pelvic rotation and other trunk shape and poor posture of male college students with S-type scoliosis.(3)Yoga's concentration of ideas,lateral breathing,relaxation,stretching and activation of core and weak chain muscles can effectively strengthen the contralateral atrophy muscle group and relax the convex tension muscle group,thus reducing the thoracic and lumbar Cobb Angle and improving scoliosis.(4)The effect of yoga exercise on improving the lung function of the subjects is not obvious.
