Abstract

Purpose: The outcomes of motor and non-motor features of Parkinson's disease (PD) following DBS vary among its subtypes. We tested whether pre-operative motor subtyping using the modified Tremor/PIGD ratio, could indicate the short-term motor, non-motor and quality of life (QOL) outcomes of STN-DBS.

Method: In this prospective study, 39 consecutive STN-DBS cases were assessed in Drug-OFF state before surgery and subtyped using the ratio of tremor and PIGD scores (T/P ratio). 6 months after surgery patients were reassessed in Stimulation ON-Drug OFF state and the percentage change in motor, non-motor and QOL scores (PDQ39) was calculated.

Results: The modified T/P ratio had a moderate, positive correlation with the percentage change in scores of UPDRS III in OFF, sum of cardinal motor signs, non-motor symptoms scale (NMSS) and quality of life (PDQ39).

Conclusion: Preoperative PD motor subtyping can be used as an indicator of the short-term, outcomes of STN-DBS in PD.

DBS前改良震颤/姿势不稳定性和步态困难评分比作为帕金森病丘脑下核DBS短期预后的指标。

目的：帕金森病（PD）脑深部电刺激后运动和非运动特征的结局因其亚型而异。我们使用改进的震颤/PIGD比率测试术前运动亚型是否可以指示STN-DBS的短期运动、非运动和生活质量（QOL）结果。方法：本前瞻性研究对39例连续STN-DBS患者进行术前off状态评估，并采用震颤与PIGD评分（T/P比）进行分型。术后6个月重新评估患者刺激ON-Drug - OFF状态，计算运动、非运动和生活质量评分（PDQ39）变化百分比。结果：改良后的T/P比值与UPDRS III评分、主要运动体征、非运动症状量表（NMSS）和生活质量（PDQ39）的百分比变化呈中等正相关。结论：术前PD运动分型可作为STN-DBS短期预后的指标。
