摘　　要：背景:脑卒中是危害中国国民健康的重大疾病之一,具有高发病率、高致残率、高死亡率及高复发率的特点。步态功能障碍或损害被认为是脑卒中最常见和最具破坏性的生理后果之一,积极的下肢康复训练可以促进步态功能的恢复,提高日常生活活动能力,改善患者的生活质量。目的:文章旨在回顾和总结适用于脑卒中后步态量化和分析的研究成果,重点是分析最新的步态分析系统、脑卒中后步态数据处理与分析技术,以及在临床环境中的可行性和潜在价值。方法:以“卒中、步态分析、评估、下肢、时空、运动学、动力学、足底压力、肌电图、机器学习、统计学”为中文检索词,以“stroke,gaitanalysis,assessment,lowerlimb,spatiotemporal,kinematics,kinetics,plantarpressure,Electromyography(EMG),machine learning,statistical”为英文检索词,分别检索中国知网及PubMed数据库。检索时间范围为2000年1月至2021年12月。通过阅读文题和摘要进行初步筛选,排除中英文文献重复性研究、低质量期刊及内容不相关的文献,最终纳入60篇文献进行综述。结果与结论:①传统的定性步态分析主要基于观察步态,具有主观性,在很大程度上受观察者经验的影响,而仪器化步态分析提供了测量的参数,具有良好的准确性和重复性,可用于整个康复过程中的诊断和评估。②快速崛起的智能可穿戴技术和人工智能,正日益引起步态研究者的更多关注:虽然它们在临床环境中的使用还没有得到很好的利用,但这些工具有望改变卒中步态量化的现状,因为它们提供了获取、存储和分析多因素复杂步态数据的手段,同时捕获了其非线性动态可变性,并提供了预测分析的宝贵好处。③在步态分析中,常通过一些特殊参数来描述步态正常与否,包括时空、运动学、动力学及肌电图参数等。了解与步行功能相关的因素可以帮助临床医生BACKGROUND:Stroke is one of the major diseases endangering the health of Chinese citizens,characterized by high morbidity,disability,mortality and recurrence.Gait dysfunction or impairment is considered to be one of the most common and devastating physiological consequences of stroke.Active lower extremity rehabilitation can promote the recovery of gait function,improve the ability to perform activities of daily living,and improve the quality of life of patients.OBJECTIVE:To review and summarize research findings applicable to post-stroke gait quantification and analysis,with a focus on the latest gait analysis system technologies,post-stroke gait data processing and analysis techniques,and their feasibility and potential value in the clinical setting.METHODS:Search terms included“stroke,gait analysis,assessment,lower limb,spatiotemporal,kinematics,kinetics,plantar pressure,electromyography(EMG),machine learning,statistics”in Chinese and English.CNKI and PubMed databases were searched for relevant articles published from January 2000 to December 2021.A few of classical distant documents were also included.The initial screening was performed by reading the titles and abstracts of the articles.Duplicate studies,low-quality journals and irrelevant documents were excluded and 62 articles were finally included for review.RESULTS AND CONCLUSION:Traditional qualitative gait analysis is primarily based on observational gait and is therefore subjective and largely influenced by the observer’s experience.Quantitative gait analysis,on the other hand,provides measured parameters with good accuracy and repeatability for diagnostic and comparative assessment throughout the rehabilitation process.The rapid development of smart wearable technologies and artificial intelligence is increasingly drawing more attention to gait research.Although their use in clinical settings is not yet well exploited,these tools are expected to change the status quo in stroke gait quantification by providing the means to acquire,store,and anal
