UNASSIGNED:矢状平衡参数的评估是脊柱手术前的标准评估。然而,这些参数在行走过程中会发生变化。我们旨在描述健康受试者在步行过程中脊柱骨盆参数的行为。
未经评估:对60名健康受试者进行了分析。评估静态脊柱矢状面平衡参数。我们进行了步态分析,并使用SMART-DX500®分析旨在定义动态矢状平衡的参数,包括骨盆倾角(PTA),矢状躯干移位(STS),和躯干角度(TA)。我们考虑了骨盆的旋转和倾斜运动,髋部的柔性伸展运动,树干,和膝盖。以站立姿势和行走进行分析。
未经批准:PTA-cycle,PTA-立场,PTA-秋千,STS循环,STS-stance,和STS摆动显示出良好到优异的内部可靠性(ICC=0.867;ICC=0.700;ICC=0.817,分别)。变异性最低的参数是射线照相PI(CV=16.53%),PTA-stance(CV=9.55%),和PTA摆动(CV=17.22%)。PT与PTA周期直接相关(r=0.534,p=0.027)。PI与躯干柔性伸展运动范围(r=-0.654,p=.004)和动态PT(r=-0.489,p=.047)呈负相关。LL和SS与膝关节屈伸直接相关(分别为r=0.505,p=0.039;r=0.493,p=0.045)。SVA与躯干倾斜度在动力学上相关(r=0.529,p=0.029)。PTA周期与树干倾斜度直接相关(r=0.538,p=0.049)。步骤的三个阶段中的STS和TA与骨盆的运动学参数有关。TA与髋关节和膝关节的柔性伸展有关。
UNASSIGNED:在步行过程中会出现动态脊柱骨盆参数的变化,并将矢状平衡从静态状态修改为动态状态。
UNASSIGNED: Evaluation of sagittal balance parameters is a standard assessment before spine surgery. However, these parameters can change during walking. We aimed to describe the behavior of spino-pelvic parameters during walking in healthy subjects.
UNASSIGNED: Analyses were performed in 60 healthy subjects. Static spinal sagittal balance parameters were assessed. We performed gait analysis and we used SMART-DX 500® to analyze parameters aimed at defining dynamic sagittal balance, including pelvic tilt angle (PTA), sagittal trunk shift (STS), and trunk angle (TA). We considered rotational and obliquity movements of the pelvis, flexo-extension movements of the hip, trunk, and knees. Analyses were performed in a standing posture and during walking.
UNASSIGNED: PTA-cycle, PTA-stance, PTA-swing, STS-cycle, STS-stance, and STS-swing showed good-to-excellent internal reliability (ICC = 0.867; ICC = 0.700; ICC = 0.817, respectively). The parameters with the lowest variability were radiographic PI (CV = 16.53%), PTA-stance (CV = 9.55%), and PTA-swing (CV = 17.22%). PT was directly related to PTA-cycle (r = 0.534, p = .027). PI was inversely correlated with trunk flexo-extension range of motion (r = -0.654, p = .004) and dynamic PT (r = -0.489, p = .047). LL and SS were directly related to knee flexo-extension (r = 0.505, p = .039; r = 0.493, p = .045, respectively). SVA was correlated with the trunk obliquity in dynamics (r = 0.529, p = .029). PTA-cycle was directly related to trunk obliquity (r = 0.538, p = .049). STS and TA in the three phases of step were related to the kinematic parameters of the pelvis. TA was related to flexo-extension of the hip and knee.
UNASSIGNED: Variations of dynamic spino-pelvic parameters occur during walking and modify sagittal balance from a static to a dynamic condition.
