目的：步态分析的最新技术进步导致了具有嵌入式压力敏感传感器的便携式走道。通常，索赔是与直接用于临床的新设备有关的。本研究的目的是评估是否功能性Ambrosion配置文件（FAP），从走道数据计算，是一个敏感的措施，在不同的慢性轻偏瘫患者的特征，由于stroke.Design：我们调查了FAP和中风的类型，患者的功能障碍，空间和时间变量的步态与压力传感器系统走道之间的关系。对25例脑卒中后偏瘫患者和31例健康人的步态变量和FAP评分进行比较。结果：患者患侧摆动期延长，非患侧站立期延长。足印压力数据显示患者患侧跖骨区的峰值压力降低，可能反映了足部轻瘫。结论：FAP评分能较好地反映患者步态的时空变化特征，但FAP评分仅在步态不急时能较好地反映步态的正常/异常。因此，当需要单个数字时，它是有用的。
Objective: Recent technical progress In gait analysis has resulted in portable walkways with embedded pressure-sensitive sensors. Often claims are made in connection with new equipment of their straightforward clinical use. The purpose of the present study was to assess whether the functional ambulation profile (FAP), calculated from walkway data, is a sensitive measure in the characterization of dissimilar patients with chronic hemiparesis due to stroke.Design: We investigated the relationships between FAP and the type of stroke, patients' functional disability, and spatial and temporal variables of gait obtained with the pressure sensor system walkway. Gait variables and FAP scores were compared in 25 patients with residual hemiparesis due to stroke and in 31 healthy subjects.Results: A prolonged swing phase in the affected side and a prolonged stance phase in the nonaffected side were found in patients. Footprint pressure data revealed reduced peak pressure of the affected-side metatarsal area in patients, probably reflecting foot paresis. Higher Barthel Index score and lower Rankin Scale score were reflected in FAP scores.Conclusions: The FAP scores of patients reflected well their characteristic spatio-temporal gait variations; however, the FAP score seemed a reliable measure of gait normality/abnormality only in rather unhurried gait. Thus, it is useful when a single number is needed.
