To validate the freezing of gait questionnaire (FOG-Q) for a Brazilian population of Parkinson's disease (PD) patients.
One hundred and seven patients with a diagnosis of PD were evaluated by shortened UPDRS motor scale (sUPDRm), Hoehn and Yahr (HY), Schwab and England scale (SE), Berg balance scale (BBS), falls efficacy scale international (FES-I), gait and balance scale (GABS), and the FOG-Q Brazilian version.
47.7% of PD patients had FOG episodes; this group had worse scores on sUPDRSm, FOGQ, FES-I, BBS, GABS and FOG item of UPDRS when compared to the PD group without FOG. The internal consistency was 0.86, intra-rater 0.82 and inter-rater 0.78. The FOG-Q Brazilian version was significantly correlated with items related to gait and balance. The ROC curve was 0.94, the sensitivity was 0.90and specificity was 0.92.
Our study suggests that the FOG-Q Brazilian version is a reliable and valid instrument for assessing FOG in PD patients.
验证帕金森病（PD）巴西患者群体的冻结步态问卷（FOG-Q）。
采用简化的统一帕金森病评定量表运动部分（sUPDRm）、霍恩和雅尔分级（HY）、施瓦布和英格兰量表（SE）、伯格平衡量表（BBS）、国际跌倒效能量表（FES-I）、步态与平衡量表（GABS）以及FOG-Q巴西版本，对107例诊断为PD的患者进行评估。
47.7%的PD患者有冻结步态发作；与无冻结步态的PD组相比，该组在sUPDRSm、FOGQ、FES-I、BBS、GABS以及UPDRS的冻结步态项目上得分更低。内部一致性为0.86，评分者内一致性为0.82，评分者间一致性为0.78。FOG-Q巴西版本与步态和平衡相关项目显著相关。ROC曲线为0.94，敏感性为0.90，特异性为0.92。
我们的研究表明，FOG-Q巴西版本是评估PD患者冻结步态的可靠且有效的工具。
