OBJECTIVE To identify the occurrence of recurrent falls and the determinants in the acute phase post stroke that are associated with recurrent falls within the first year after stroke onset. DESIGN Prospective follow-up study. SETTING Stroke unit and community. PARTICIPANTS 504 patients with acute stroke. INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES The dependent variable was recurrent falls, defined as two or more falls, within the first year after stroke onset. The independent baseline variables were related to function, activity, participation, personal and environmental factors and comorbidity and were assessed within four days after admission to a stroke unit. Fall data were registered at the stroke unit and self-reported fall data were collected during follow-up using a standardized questionnaire. Determinants of recurrent falls were identified using univariable and multivariable logistic regression analyses. RESULTS Within 12 months after stroke onset, 95 of 348 participants (27%) had experienced recurrent falls. Poor postural control (odds ratio [OR] 5.85, 95% confidence interval [CI] 2.84-12.02, P<.0001), moderate postural control (OR 2.41, 95% CI 1.21-4.80, P=.012) and using a walking aid in the acute phase (OR 2.51, 95% CI 1.45-4.36, P=.0010) are statistically significant determinants that are associated with recurrent falls within the first year after stroke onset. The determinant of using a walking aid appears to be primarily driven by those younger than 80 years. In addition to impaired postural control and using a walking aid, a fall at the stroke unit is a determinant associated with recurrent falls after discharge within 6 months after stroke onset. CONCLUSIONS More than one in four individuals with stroke experienced recurrent falls within the first year after stroke onset. Impaired postural control, using a walking aid in the acute phase and fall during hospitalization are determinants associated with recurrent falls during follow-up. The determinants differ somewhat at different ages.

中风后反复跌倒的决定因素：哥德堡秋季研究的一年随访

目的 确定复发性跌倒的发生率以及与中风发作后第一年内复发性跌倒相关的中风后急性期的决定因素。设计 前瞻性随访研究。设置中风单位和社区。参与者 504 名急性卒中患者。干预 不适用。主要结局指标 因变量是复发性跌倒，定义为中风发作后第一年内跌倒两次或两次以上。独立的基线变量与功能、活动、参与、个人和环境因素以及合并症有关，并在进入卒中单元后四天内进行评估。在卒中单元登记跌倒数据，并在随访期间使用标准化问卷收集自我报告的跌倒数据。使用单变量和多变量逻辑回归分析确定反复跌倒的决定因素。结果 中风发作后 12 个月内，348 名参与者中有 95 名 (27%) 反复跌倒。姿势控制差（比值比 [OR] 5.85，95% 置信区间 [CI] 2.84-12.02，P<.0001），姿势控制中等（OR 2.41，95% CI 1.21-4.80，P=.012）并使用急性期助行器（OR 2.51，95% CI 1.45-4.36，P=.0010）是与卒中发病后第一年内反复跌倒相关的具有统计学意义的决定因素。使用助行器的决定因素似乎主要是由 80 岁以下的人驱动的。除了姿势控制受损和使用助行器外，卒中单元跌倒是卒中发病后 6 个月内出院后反复跌倒的决定因素。结论 超过四分之一的中风患者在中风发作后的第一年内反复跌倒。姿势控制受损、急性期使用助行器和住院期间跌倒是随访期间反复跌倒的决定因素。决定因素在不同年龄略有不同。
