INTRODUCTION
Deep brain stimulation (DBS) with high frequency (HFS) is a well-established therapy for Parkinson's disease (PD); however, low frequency DBS (LFS) may control axial symptoms including freezing of gait (FOG). We conducted a pilot safety and feasibility study to examine if a novel DBS paradigm of variable frequency stimulation (VFS) that combined HFS and LFS would capture a broader set of motor symptoms.
METHODS
Four PD patients with bilateral STN DBS and FOG were enrolled. A UPDRS III and 10 m timed up and go (TUG) task were performed off medications-off DBS and then one hour after HFS and one hour after VFS programming.
RESULTS
The UPDRS III motor score improved by additional 14% during VFS setting when compared to HFS. VFS also increased gait speed (mean change 45%) and reduced the number of freezing episodes (mean change 58%).
CONCLUSIONS
VFS improves UPDRS and FOG in PD when compared to HFS.Copyright © 2018 International Parkinson and Movement Disorder Society.
引言
高频深部脑刺激（DBS）是治疗帕金森病（PD）的一种成熟疗法；然而，低频DBS（LFS）可能控制包括步态冻结（FOG）在内的轴性症状。我们开展了一项初步安全性和可行性研究，以检验一种将高频刺激（HFS）和低频刺激相结合的新型可变频率刺激（VFS）DBS模式是否能控制更广泛的运动症状。
方法
招募了4例双侧丘脑底核DBS且有FOG的PD患者。在关药-关DBS状态下，以及在HFS编程后1小时和VFS编程后1小时进行统一帕金森病评定量表第三部分（UPDRS III）和10米计时起立行走（TUG）任务。
结果
与HFS相比，VFS设置期间UPDRS III运动评分额外提高了14%。VFS还提高了步态速度（平均变化45%），并减少了冻结发作次数（平均变化58%）。
结论
与HFS相比，VFS可改善PD患者的UPDRS和FOG。版权所有©2018国际帕金森病和运动障碍协会。
