Drop foot syndrome is a disorder characterized by foot slapping after the initial contact and foot-dragging during the swing phase. Passive and hybrid passive ankle foot orthoses (AFOs) are often prescribed in these patients; however, the effects of these AFO designs on kinematic parameters during gait are unclear. The aim of this study was to compare the effect of innovative designed storing-restoring hybrid passive AFOs versus posterior leaf spring AFO on ankle joint kinematics in drop foot patients. The present study was a case series where a single case and 3 cases with drop foot syndrome were recruited. This study was designed in 2 phases: the baseline phase with their PLS AFOs and an intervention phase in which innovative designed AFO were assessed. Each phase included 5 measurement sessions which were performed in 5 consecutive weeks. The celeration line method was used to detect the significant differences between the phases. The results of this study showed a significant increase in the kinematic angles parameters at the initial contact, the loading response, the mid stance, terminal stance, pre swing, initial swing, mid swing, and terminal swing with the innovative designed AFO than with PLS AFO (p<0.05). The results of the present study suggested that use of the innovative designed AFO may have a positive effect on ankle joint kinematics parameters in people with drop foot.
垂足综合征是一种以初始接触后足掌拍击和摆动期拖足为特征的病症。这些患者常被开具被动式和混合被动式踝足矫形器（AFO）；然而，这些AFO设计对步态期间运动学参数的影响尚不清楚。本研究的目的是比较创新设计的存储 - 恢复混合被动式AFO与后叶弹簧AFO对垂足患者踝关节运动学的影响。本研究是一个病例系列，招募了1例单病例和3例垂足综合征病例。本研究分为两个阶段设计：使用后叶弹簧AFO的基线阶段和评估创新设计AFO的干预阶段。每个阶段包括连续5周进行的5次测量。采用加速度线法检测各阶段之间的显著差异。本研究结果显示，与后叶弹簧AFO相比，使用创新设计的AFO时，在初始接触、负重反应、站立中期、站立末期、摆动前期、初始摆动、摆动中期和摆动末期的运动学角度参数显著增加（p<0.05）。本研究结果表明，使用创新设计的AFO可能对垂足患者的踝关节运动学参数有积极影响。
