To evaluate the differences in gait characteristics and gait symmetry of post-polio syndrome (PPS) patients ambulating with or without shoes and between subgroups walking with different walking aids and orthoses, study the correlation of these data with personal data, illness condition, physical health, frequency of using aids and orthotics and frequency of falls, and derive recommendations for standardization of reporting these data.
Twenty-six PPS subjects ambulated with their own walking devices. We calculated spatio-temporal parameters and symmetry indices (SI) of gait using a data acquired by a motion capture system. We compared inter-subject differences in gait pattern for PPS groups that differed by questionnaire-obtained data of demographics, physical activity, polio history, falls and walking aids. Additional inter-subject comparisons were performed between normal subjects (n=16), PPS patients walking with shoes with/without an ankle-foot-orthosis (n=11), PPS patients walking with knee-ankle-foot-orthosis (n=5), and PPS patients walking with a walker/crutches (n=10). We also compared intra-subject variability in PPS subjects who were able to repeat the trials barefoot.
Our main results show that subjects who reported participating in physical activity twice a week or more had significantly better step time and double support symmetry. Subjects who use walking aids on a daily basis had significantly higher gait cadence and shorter stride time. Also, subjects that do not require knee-ankle-foot orthoses and/or walking aids walked with a smaller base width and better symmetry in stance and swing durations than PPS subjects who require these aids.
The gait pattern of PPS patients is related to numerous intrinsic and extrinsic factors. Standardization of the reporting protocol of gait-related data of PPS patients is crucial for patient evaluation and treatment design.
评估使用或不使用鞋子行走的肌萎缩侧索硬化后综合征（PPS）患者的步态特征和步态对称性差异，以及使用不同助行器和矫形器行走的亚组之间的差异，研究这些数据与个人数据、疾病状况、身体健康、助行器和矫形器使用频率以及跌倒频率之间的相关性，并为报告这些数据的标准化提供建议。
26 名 PPS 患者使用自己的行走装置进行行走。我们使用运动捕捉系统获取的数据计算了步态的时空参数和对称指数（SI）。我们比较了问卷调查获得的人口统计学、身体活动、脊髓灰质炎病史、跌倒和助行器使用数据不同的 PPS 组之间的步态模式的个体间差异。还在正常受试者（n=16）、穿着鞋子且带有/不带有踝足矫形器（n=11）、膝踝足矫形器（n=5）和助行器/拐杖（n=10）行走的 PPS 患者之间进行了额外的个体间比较。我们还比较了能够赤脚重复试验的 PPS 患者的个体内变异性。
我们的主要结果表明，每周参加两次或两次以上体育活动的患者的步时和双支撑对称性显著更好。每天使用助行器的患者步频明显更高，步幅时间更短。此外，不需要膝踝足矫形器和/或助行器的患者行走时的支撑宽度更小，站立和摆动时间的对称性更好，而需要这些助行器的 PPS 患者则相反。
PPS 患者的步态模式与许多内在和外在因素有关。PPS 患者步态相关数据报告协议的标准化对于患者评估和治疗设计至关重要。
