步态对称性是人体步态的重要特征之一, 客观量化步态对称性是步态分析研究领域广泛关注的热点问题.综述分析近30年相关研究相继提出的基于离散量化分析、连续量化分析和统计量化分析的步态对称性客观量化评价方法, 可穿戴、网络化、智能化已成为当前量化评价步态对称性的主要技术特点.探寻新的步态对称性模型、新的步态对称性量化指标, 先进的量化评价步态对称性技术手段是当前相关研究亟待解决的关键问题和未来的发展趋势.%Gait symmetry is one of the important characteristics of human gait. Objectively quantifying the gait symmetry is a hot issue that has attracted extensive attention in the field of gait analysis. This paper reviewed the objective quantitative evaluation methods of gait symmetry based on discrete quantitative analysis, continuous quantitative analysis and statistical quantitative analysis, which have been put forward successively in related research in the past 30 years. Wearable, networked, and intelligent have become the main technical characteristics of the symmetry of the current quantitative evaluation gait. Searching for new gait symmetry models, new gait symmetry quantitative indicators, and advanced quantitative gait symmetry technical measures are the key issues that need to be addressed in current related research and future development trends.
