目的：调查帕金森病（Parkinson disease，PD）患者的居家跌倒情况，以及居家环境因素对居家跌倒发生的影响。方法：采用便利抽样法，纳入2020年5月—2022年9月期间于我院功能神经外科就诊的260例PD患者，根据患者在调查前近3个月内有无跌倒史，将其分为跌倒组和未跌倒组。采用一般资料以及居家跌倒情况调查表、运动障碍协会（Movement Disorder Society，MDS）PD统一评定量表Ⅲ（MDS unified-PD rating scale Ⅲ, MDS UPDRS-Ⅲ）、左旋多巴日等效剂量（levodopa equivalent daily dose, LEDD）和居家跌倒风险筛查（home falls and accidents screening tool，HOME FAST）量表进行问卷调查。结果：57例（22.5%）患者调查前近3个月内发生过跌倒，其中19例（33.3%）多次跌倒，49例（86.0%）在室内跌倒，51例（89.5%）主要发生在白天，49例（86.0%）跌倒时为单独一人。居家环境因素中，地板（84.5%）和卫生间（63.2%）没有防滑垫为最常见的问题。跌倒组PD患者居家跌倒风险评估总分低于未跌倒组[（19.84±3.72）分比（21.27±2.72）分，t=3.190，P=0.002]。多因素Logistic回归分析显示，通道有杂乱物品 [优势比（odds ratio, OR）=1.214，P=0.003]以及楼梯旁没有扶手（OR=1.333，P=0.028）是PD患者居家跌倒的主要环境危险因素。结论：PD患者居家跌倒发生率高，居家环境对于PD居家跌倒的发生有影响，通道有杂物以及楼梯旁没有扶手是PD患者跌倒的主要危险因素。

Objective To investigate the influence of home environment on the incidence of home falls in patients with Parkinson disease (PD). Methods Using a convenience sampling method, 260 patients with PD treated in the functional neurosurgery department of our hospital from May in 2020 to September in 2022 were enrolled as study projects. The patients were divided into non-home fall group and home fall group based on whether they had fallen in the past three months. A questionnaire survey including general information and home falls questionnaire, Movement Disorder Society (MDS) unified PD disease rating scale Ⅲ (UPDRS-Ⅲ), levodopa equivalent daily dose (LEDD) and home falls and accidents screening tool (HOME FAST) was conducted, and the collected data was analyzed. Results There were 57 (22.5%) patients had fallen in the previous three months, 19 (33.3%) patients fell several times, 49 (86.0%) patients fell indoors, 51 (89.5%) patients fell mainly during the daytime, and 49(86.0%) patients fell without accompany. In the home environment, floor (84.5%) and toilet (63.2%) without anti-slip pads were the most common reason to lead to fall. The total score of HOME FAST in the home fall group was lower than that in the non-home fall group [(19.84±3.72) vs (21.27±2.72), t=3.190, P=0.002]. Multivariate Logistic regression analysis showed that sundry objects in the passageway[odds ratio (OR)=1.214, P=0.003] and the lack of handrails beside the stairs (OR=1.333, P=0.028) were the major risk factors of home falls. Conclusions There is high incidence of home falls in PD patient, and the home environment have an impact on the occurrence of home falls. Sundry objects in the passageway and the lack of handrails beside the stairs are the major risk factors of home falls in patients with PD.
