Abstract

Background: Wider step width and lower step-to-step variability are linked to improved gait stability and reduced fall risk. It is unclear if patients with spinocerebellar ataxia (SCA) can learn to adjust these aspects of gait to reduce fall risk.

Objectives: The aims were to examine the possibility of using wearable step width haptic biofeedback to enhance gait stability and reduce fall risk in individuals with SCA.

Methods: Thirteen people with SCA type 3 performed step width training (single session) using real-time feedback.

Results: Step width increased post-training (19.3 cm, interquartile range [IQR] 16.3-20.2 cm) and at retention (16.6 cm, IQR 16.2-21.1 cm), compared to baseline (11.0 cm, IQR 5.2-15.2 cm; P < 0.001). Step width variability decreased during post-training (19.7%, IQR 17.4%-26.2%) and at retention (22.3%, IQR 18.6%-30.2%), compared to baseline (44.5%, IQR 28.5%-71.2%; P < 0.001). Crossover steps, another mark of instability, decreased after training (P < 0.031).

Conclusions: These pilot results suggest that patients with SCA can use a novel, wearable biofeedback system to improve their gait stability. © 2025 International Parkinson and Movement Disorder Society.

步宽触觉反馈对脊髓小脑性共济失调患者步态稳定性的影响：初步结果。

背景：更宽的步宽和更低的步间变异性与改善步态稳定性和降低跌倒风险有关。目前尚不清楚脊髓小脑性共济失调（SCA）患者是否能够学会调整这些方面的步态以减少跌倒的风险。目的：目的是研究使用可穿戴步宽触觉生物反馈增强SCA患者步态稳定性和降低跌倒风险的可能性。方法：13例SCA 3型患者采用实时反馈进行步宽训练（单次）。结果：与基线（11.0 cm, IQR 5.2-15.2 cm）相比，训练后（19.3 cm，四分位间距[IQR] 16.3-20.2 cm）和保持时（16.6 cm, IQR 16.2-21.1 cm）步宽增加；结论：这些试点结果表明，SCA患者可以使用一种新型的可穿戴生物反馈系统来改善他们的步态稳定性。©2025国际帕金森和运动障碍学会。
