摘　　要：目的了解中度Lenke 3CN型女性青少年特发性脊柱侧弯(adolescent idiopathic scoliosis,AIS)与同龄健康青少年的静态平衡足底压力特征差异,为青少年脊柱侧弯的筛查、评估、治疗和评价预后提供科学依据。方法选取30例中度Lenke 3CN型女性青少年特发性脊柱侧弯为AIS组,30例同龄健康女性青少年为对照组,采集静态平衡足底压力数据,比较分析两组足底压力分布特征。结果足底压力特征方面,AIS组左、右足的平均压力(P<0.05)和后足压力(P<0.05)均显著大于对照组,前足压力均显著小于对照组(P<0.05),双足对称性指数(symmetry index,SI)显著大于对照组(P<0.05)。AIS组左足的足中内侧区和第1脚趾区足底压力显著大于对照组(P<0.05),第1、2、3、4、5跖骨区足底压力显著小于对照组(P<0.05);AIS组右足的足跟内侧区和第1脚趾区足底压力显著大于对照组(P<0.05),足中外侧区、第3、4、5跖骨区和第3、4、5脚趾区足底压力显著小于对照组(P<0.05)。足底压力中心(center of pressure,COP)方面,AIS组足底COP轨迹长度、95%信赖区间椭圆面积、COP左-右移动最大距离(COP-X)和COP前-后移动最大距离(COP-Y)均显著大于对照组(P<0.05)。结论中度Lenke 3CN型AIS患者与同龄健康青少年的静态平衡足底压力特征存在显著性差异,足部压力会偏向侧弯凸侧,双足的对称性、稳定性较差,平衡控制能力较弱。Objective To analyze the differences in static balance plantar pressure characteristics between female adolescent idiopathic scoliosis(AIS)patients with moderate Lenke 3CN and healthy adolescents of the same age,and provide a scientific basis for scoliosis screening,assessment,treatment,and prognosis evaluation.Methods A total of 30 female patients with moderate Lenke 3CN AIS as the AIS group and 30 healthy female adolescents of the same age as the control group were selected,respectively.The plantar pressure data of the subjects were collected,and the characteristics of equilibrium plantar pressure distributions in two groups were comparatively analyzed.Results Regarding the plantar pressure characteristics,the average pressure(P<0.05)and hindfoot pressure(P<0.05)of the left and right foot in the AIS group were significantly greater thanthose of the control group,the forefoot pressure was significantly lower than that of the control group(P<0.05),and the symmetry index(SI)of both feet was significantly greater than that of the control group(P<0.05).Theplantar pressure of the left foot in the AIS group was significantly larger than that of the control group in the medialmid-foot area and 1st toe area(P<0.05),and significantly smaller than that of the control group in the 1st,2nd,3rd,4th and 5th metatarsal areas(P<0.05);the plantar pressure of the right foot in the AIS group was significantlygreater than that of the control group in the medial heel area and the1st toe area(P<0.05),and significantlysmaller than that of the control group in the lateral mid-foot area,the 3rd,4th,5th metatarsal area and 3rd,4th,5thtoe area(P<0.05);and the plantar pressure in the right foot of the AIS group was significantly smaller than thatof the control group in the medial heel area and 1st toe area(P<0.05).The plantar pressures at lateral midfootarea,the 3rd,4th,5th metatarsal area and the 3rd,4th,5th toe area of the right foot were significantly larger thanthose of the control group(P<0.05).Regarding the center of pressure(COP),th
