Nowadays, bipedal walking is undergoing extensive study. Several methods can be used in physiotherapeutic research for identifying defects in bipedal walking as a result of pathology of the musculoskeletal or nervous system. Our work focuses on studying asymmetry of walking based on synchronized bilateral knee-knee cyclograms. Participants presenting with peroneal nerve palsy and foot drop were included in the study. The bilateral cyclograms, also called angle-angle diagrams, were created to quantify gait asymmetry before and immediately after application of a brace. In order to quantify the asymmetry of human walking, we have described and tested the application of the method based on the inclination angle of the synchronized bilateral cyclograms. The symmetry index (SI) was used as a comparative method to evaluate the symmetry of bipedal walking. The method based on the orientation of the cyclograms can be used as an additional method for determining the gait asymmetry. The new technique has never been applied before to study the gait asymmetry in patients with peroneal nerve palsy or patients with leg brace.
如今，双足行走正在接受广泛研究。在物理治疗研究中，可以使用几种方法来识别由于肌肉骨骼或神经系统病变导致的双足行走缺陷。我们的工作重点是基于同步双侧膝关节周期图来研究行走的不对称性。研究纳入了患有腓总神经麻痹和足下垂的参与者。创建双侧周期图，也称为角度-角度图，以量化佩戴支具前后的步态不对称性。为了量化人类行走的不对称性，我们描述并测试了基于同步双侧周期图倾斜角度的方法的应用。对称指数（SI）被用作评估双足行走对称性的比较方法。基于周期图方向的方法可以用作确定步态不对称性的附加方法。这项新技术以前从未应用于研究腓总神经麻痹患者或佩戴腿部支具患者的步态不对称性。
