人体步态质量主元量化评定方法的研究

Quantitative Gait Evaluation Using Principal Component Analysis

人体步态功能的评定在临床医学、康复工程等领域中有着重要作用。本文提出了一种步态质量的主元量化评定方法。评定步骤为,将步态检测得到的原始数据分类形成指标体系,按照主元分析方法将指标进行归一化量化处理、计算,提出综合评定指标,然后用公式和图表方式表达步态功能的量化评定结果。实例研究表明主元量化评定方法能有效评价步态治疗的恢复情况。

Evaluation of human gait function is of great significance in clinical medicine and rehabilitation engineering. A quantitative gait evaluation method using principal component analysis was proposed. The evaluation steps included that a series of characteristic index was performed by the gait parameters with a gait detection, and the index was normalized, quantified and summarized by principal component analysis. Then the evaluation results were shown in formulation, figures and tables. The examples showed that this system could evaluate the recovery of the gait by treatment.
