运动学步态分析是一种重要的非侵入性技术，用于定量评估和描述健康和受伤人群的运动和其他运动。三维（3D）运动学分析提供了额外的结局指标，包括未使用矢状面（2D）分析技术表征的内外旋。本研究的目的是：1）使用关节坐标系开发和评价用于猫步态分析的3D后肢多平面运动学模型，2）实施和比较两种3D后膝关节（膝关节）预测技术，以及3）比较使用多平面模型与矢状面模型确定的屈曲-伸展。在3只雌性成年猫（年龄= 2.9岁，体重= 3.5 ± 0.2 kg）中记录行走步态。运动学结果包括髋关节、后膝关节和踝关节的屈曲-伸展、内外旋和外展-内收。每种多平面后膝关节预测技术得出的结果相似。使用放置在体内骨标志上方皮肤上的标记物确定的关节角度与使用猫后肢骨骼确定的关节角度相似，其中标记物直接放置在离体标志物上。当比较多平面模型和矢状面模型时，证实了髋关节、后膝关节和跗关节屈伸的差异。这种多平面猫运动学模型可以预测关节旋转运动学，作为一种工具，可以量化额，横向和矢状面运动。该模型具有多个优点，因为它能够表征关节内-外旋和外展-内收。另一个重要的好处是更准确地表示关节屈曲-伸展运动。
Kinematic gait analysis is an important noninvasive technique used for quantitative evaluation and description of locomotion and other movements in healthy and injured populations. Three dimensional (3D) kinematic analysis offers additional outcome measures including internal-external rotation not characterized using sagittal plane (2D) analysis techniques. The objectives of this study were to 1) develop and evaluate a 3D hind limb multiplane kinematic model for gait analysis in cats using joint coordinate systems, 2) implement and compare two 3D stifle (knee) prediction techniques, and 3) compare flexion-extension determined using the multiplane model to a sagittal plane model. Walking gait was recorded in 3 female adult cats (age = 2.9 years, weight = 3.5 ± 0.2 kg). Kinematic outcomes included flexion-extension, internal-external rotation, and abduction-adduction of the hip, stifle, and tarsal (ankle) joints. Each multiplane stifle prediction technique yielded similar findings. Joint angles determined using markers placed on skin above bony landmarks in vivo were similar to joint angles determined using a feline hind limb skeleton in which markers were placed directly on landmarks ex vivo. Differences in hip, stifle, and tarsal joint flexion-extension were demonstrated when comparing the multiplane model to the sagittal plane model. This multiplane cat kinematic model can predict joint rotational kinematics as a tool that can quantify frontal, transverse, and sagittal plane motion. This model has multiple advantages given its ability to characterize joint internal-external rotation and abduction-adduction. A further, important benefit is greater accuracy in representing joint flexion-extension movements.
