OBJECTIVE
This paper reports a method of using a multi-axis graph to represent the range of rotations at the hip and knee joints during gait for clinical evaluation of a patient's performance.
DESIGN AND METHODS
The multi-axis graph uses 12 symmetrically arranged axes to represent each component of range of rotations at the hip and knee joints of both legs. The range of joint rotations of thirteen normal subjects and two patients were measured using an electromagnetic motion tracking system with four foot switches.
RESULTS
The range of joint rotations of normal subjects shows a symmetrical star in the multi-axis graph. Abnormal function of a patient shows an asymmetrical star.
CONCLUSIONS
This representation provides a simple way to examine a patient's performance in a time effective manner. Relevance. In clinical practice, the multi-axis representation of joint rotations can be used as an initial evaluation of a patient's performance to identify problems for further investigation.
目的
本文报告一种使用多轴图来表示步态期间髋关节和膝关节旋转范围的方法，用于临床评估患者的表现。
设计与方法
多轴图使用12个对称排列的轴来表示双腿髋关节和膝关节旋转范围的每个组成部分。使用带有四个脚踏开关的电磁运动跟踪系统测量了13名正常受试者和两名患者的关节旋转范围。
结果
正常受试者的关节旋转范围在多轴图中显示为对称的星形。患者的异常功能显示为不对称的星形。
结论
这种表示方式提供了一种简单的方法，能够及时有效地检查患者的表现。相关性：在临床实践中，关节旋转的多轴表示可用于对患者表现进行初步评估，以识别问题以便进一步调查。
