强直性脊柱炎（AS）是一种慢性炎症性疾病，主要影响中轴骨骼，包括骶髂关节、肋椎关节和脊柱。AS患者发现步态模式改变。本研究的目的是研究严重AS后凸患者手术矫正后步态的生物力学改变。方法采用实验室对照研究，采用前测后测设计。一名20岁男性，因AS表现出严重的矢状位失衡和无法直立。患者表现为胸部后凸70°，腰椎后凸25°，骨盆后凸43°。患者进行了复杂的脊柱重建，矢状面矫正84°，使其矢状面对齐正常化。术前1天和术后1个月进行步态分析，包括三维运动学、地面反作用力和肌电图结果。
Background Ankylosing spondylitis (AS) is a chronic inflammatory disease primarily affecting the axial skeleton, including the sacroiliac joints, costovertebral joints, and the spine. Patients with AS found to have an alter gait pattern. The purpose of this study was to investigate biomechanical alterations in gait after surgical correction in a patient with severe kyphosis from AS. Methods A case report in controlled laboratory study, a pretest-posttest design. A 20 year-old male presented with severe sagittal imbalance and inability to stand erect due to AS. He presented with thoracic kyphosis of 70°, lumbar kyphosis of 25°, and pelvic incidence of 43°. The patient had a complex spinal reconstruction with 84° of sagittal correction, normalizing his sagittal alignment. Gait analysis was performed the day before surgery and one month post surgery, including three-dimensional kinematics, ground reaction forces, and electromyography outcomes.
