Spinal and rib cage 3-D kinematics during breathing for normal subjects and adolescent idiopathic scoliotics

Abstract

脊柱側彎患者呼吸功能減退的病因學至今尚無定論。力學因素很可能是呼吸功能減退的原因之一。通過比較脊柱側彎患者與正常人深呼吸時胸段脊柱及胸廓三維運動來探討力學因素對呼吸功能減退的影響。用Elite運動分析系統（BTS，Italy）測量了42名特發性脊柱側彎患者及21名正常人脊柱及胸廓三維運動，脊柱側彎患者的胸廓三維運動顯著低于正常人，脊柱相對僵直，活動度減低。脊柱側彎患者胸廓及脊柱骨架的僵直有可能是影響呼吸動力學的原因之一。 Recent studies fail to explain completely the causes of pulmonary function impairment in scoliotics. It was suggested that mechanical factors might be involved in the cause of the reduction in pulmonary function. The aim of this study was to compare the rib cage and thoracic spine 3-D movements,and the spina1 stiffness between the scoliotics and normal subjects. Rib cage and spine 3-D movements were collected using Elite motion analysis system (BTS, ltaly) from 42 adolescent idiopathic scoliotics and 21 normal subjects. The patients showed significant smaller movements three dimentionally.In addition, the scoliotic patients showed less movements and stiffer spines during deep breathing in comparison to normal subjects.
