Supplementary Material for: A Patient-Invented Maneuver to Alleviate Freezing of Gait Using a Foot Loop Band

Freezing of gait (FOG) is a disabling gait disorder in parkinsonian patients characterized by the inability to initiate or continue locomotion. I herein present a 65-year-old man with Parkinson's disease who invented a unique method (foot loop band) to alleviate FOG, which has not been previously described in the literature. The mechanisms to alleviate FOG include not only facilitating mechanical weight shift, but also restoring internal cueing and driving motor commands for gait initiation. This patient-invented maneuver may be recommended for patients having intractable FOG, because it is portable, cheap and safe.

步态冻结（Freezing of Gait, FOG）是帕金森病患者群体中一类致残性步态障碍，以无法启动或维持行进过程为典型特征。本文报告一例65岁帕金森病男性患者，其自主研发了一种名为足环带（foot loop band）的独特方法以缓解步态冻结，该方法此前尚未见文献报道。该方法缓解步态冻结的作用机制不仅包括促进机械性体重转移，还可恢复内部线索并驱动步态启动所需的运动指令。鉴于该方法具备便携、廉价且安全的优势，可推荐给难治性步态冻结患者采用。
