To study the use of auditory feedback for gait management and rehabilitation in patients with Multiple Sclerosis (MS).
An auditory feedback cue, responding to the patient's own steps in closed-loop, was produced by a wearable motion sensor and delivered to the patient through ear phones. On-line (device on) and residual short-term therapeutic effects on walking speed and stride length were measured in fourteen randomly selected patients with gait disturbances predominantly due to cerebellar ataxia.
Patients showed an average improvement of 12.84% on-line and 18.75% residually in walking speed. Average improvement in stride length was 8.30% on-line and 9.93% residually. The improvement results are particularly noteworthy when compared with the lack of change in healthy control subjects.
Patients with MS using auditory feedback cues showed improvement in walking abilities.
研究听觉反馈在多发性硬化症（MS）患者步态管理与康复中的应用。
可穿戴运动传感器产生一种闭环响应患者自身步幅的听觉反馈提示，并通过耳机传递给患者。对14名随机选取的、主要因小脑共济失调导致步态障碍的患者，测量了在线（设备开启）状态下以及残留的短期治疗效果对步行速度和步幅的影响。
患者在线状态下步行速度平均提高了12.84%，残留效果下提高了18.75%。步幅在线平均提高8.30%，残留效果下提高9.93%。与健康对照受试者无变化相比，这些改善结果尤为显著。
使用听觉反馈提示的MS患者步行能力有所改善。
