摘要

Adolescence idiopathic scoliosis (AIS) is a spinal column deformity that often occurs in children during adolescence Pathologically when the growth speed on both sides of the vertebral is unequal the thickness of the vertebral body is different and leads to scoliosis Consequently the length-tension relationship of the muscles on the sides of the spine is imbalanced progressively Patients with scoliosis have poor posture and may even have poor cardiopulmonary function when this condition becomes severe Pain accompanied by neuromuscular dysfunction may cause Activities of daily living (ADLs) disability According to research only bracing treatments and surgical operations can effectively control the deterioration and correction of scoliosis The correction principal of a traditional brace is based on a three-point compression system The brace gives opposite force to the apex of the curve and fixation to both ends at the same time As a result a traditional brace is used to treat curves with Cobb angles between 20 degrees and 45 degrees According to clinical statistics among traditional braces the Boston Brace has the best correction effect However it can only maintain and avoid deterioration of the spine Hence a lot of medical experts believe that the brace can only maintain and does not treat or correct Because reduction of the Cobb angle is often only shown on the X-ray of the patient with a brace and once the brace is removed the Cobb angel returns to the initial condition The airbag brace is modified from the Boston Brace Its corrective force comes from not only the tension stripe behind the brace but also from an airbag filled with air within the brace to increase the pressure pushing on the spine This study targets 20 AIS subjects (aged 6-16) and supplies them with their own airbag braces in order to do research on the corrective effects The data analysis of the results indicates effective correction Compared with the Boston Brace the most significant difference is that a reduction in the Cobb angel is obtained after the brace is removed This research is intended to discuss two factors related to the airbag brace: 1) the external factor consisting of the corrective force of the skin-orthotic interface and 2) the internal factor consisting of the back muscle (erector spinae) activity in order to understand how the interface pressure contact area and muscle activity are influenced by an airbag brace and exercise The use of this brace not only improves the components of any brace but also introduces a new therapy to exercise therapy to increase the correction effect The results show that it is workable to replace a fixed shape brace with an air bag that is deformable with pressure The contact pressure contact area and force (8 91±4 19 kPa 379 14±73 96 cm2 and 351 43±187 8 N) are similar to those of an earlier research paper and the three parameters stay within a certain range Moreover a long track indicates that the airbag brace has a significant effect on reducing the Cobb angel (p
