To compare the effects of gait training with distinct glide-symmetric visual feedback cues, adapted to the geometry of human locomotion, to the effects of training with visual cues of no distinct symmetry, on the walking abilities of subjects with gait disorders due to multiple sclerosis (MS).
Ten patients trained with transverse lines while 11 patients trained with checkerboard tiles, both provided by a wearable virtual reality device. Baseline performance (walking speed and stride length along a 10 m straight track) was measured before device use. Following 20 min training with the device and 10 min rest, performance without the device was measured again and compared to the baseline performance.
The average improvement in the group using the visual cue of transverse lines was 7.79% +/- 4.24% in walking speed and 7.20% +/- 3.92% in stride length. The average improvement in the group using the visual cue of checkerboard tiles was 21.09% +/- 18.39% in walking speed and 12.99% +/- 1.72% in stride length.
Patients with gait disorders due to MS, training with a glide-symmetric visual feedback cue, showed a significantly higher improvement in their gait parameters than patients training with a visual feedback cue of no without distinct symmetry.
比较采用适应人体运动几何形状的独特滑动对称视觉反馈线索进行步态训练，与采用无明显对称性视觉线索进行训练，对多发性硬化症（MS）所致步态障碍患者步行能力的影响。
10名患者使用可穿戴虚拟现实设备提供的横线进行训练，11名患者使用棋盘格瓷砖进行训练。在使用设备前测量基线表现（沿10米直线轨道的步行速度和步幅）。在使用该设备进行20分钟训练并休息10分钟后，再次测量不使用设备时的表现，并与基线表现进行比较。
使用横线视觉线索的组，步行速度平均提高7.79%±4.24%，步幅平均提高7.20%±3.92%。使用棋盘格瓷砖视觉线索的组，步行速度平均提高21.09%±18.39%，步幅平均提高12.99%±1.72%。
与使用无明显对称性视觉反馈线索训练的患者相比，MS所致步态障碍患者采用滑动对称视觉反馈线索训练后，其步态参数改善明显更大。
