The Gait Profile Score (GPS) is a single index measure that summarises the overall deviation of kinematic gait data relative to normative data. The GPS can be decomposed to provide Gait Variable Scores (GVS) of nine key component kinematic gait variables, which are presented as a Movement Analysis Profile (MAP). The purpose of this study was to investigate the validity of the GPS and MAP relative to clinician judgments. Kinematic data were selected from 60 children and inspected by 17 experienced clinicians. The degree of abnormality of the overall unilateral gait pattern and the nine kinematic variables was rated according to a 0-10 point scale. Strong, significant, positive correlations were found between the GPS and MAP component scores, and clinicians' ratings of kinematic gait deviation, with Spearman correlations ranging from 0.84 to 0.97. These high correlations provide evidence that the GPS and the MAP have criterion-related validity relative to clinician judgments. We propose that the GPS and particularly its MAP decomposition may be useful in clinical practice and education as an adjunct to the traditional presentation of complex kinematic data.
步态分析评分（GPS）是一个单一指标，用于总结相对于标准数据的运动学步态数据的整体偏差。GPS 可以分解为九个关键运动学步态变量的步态变量评分（GVS），并以运动分析图（MAP）的形式呈现。本研究旨在探讨 GPS 和 MAP 相对于临床医生判断的有效性。从 60 名儿童中选择运动学数据，并由 17 名经验丰富的临床医生进行检查。根据 0-10 分制对整体单侧步态模式和九个运动学变量的异常程度进行评分。GPS 和 MAP 分量评分与临床医生对运动学步态偏差的评分之间存在很强的、显著的正相关，Spearman 相关系数范围为 0.84 至 0.97。这些高度相关的结果表明，GPS 和 MAP 相对于临床医生的判断具有准则相关的有效性。我们提出，GPS 特别是其 MAP 分解可能在临床实践和教育中作为复杂运动学数据传统呈现的辅助手段有用。
