背景和目的——本研究的目的是确定大脑半球一侧病变是否影响卒中后推行为(PB)的发生率和时程。方法——共调查1660例急性卒中患者。使用标准化的反向推力量表评估 PB。使用风险比来评估右大脑半球损伤（RCD）和左大脑半球损伤（LCD）患者之间PB患病率的差异。通过使用 Kaplan-Meier 方法使用对数秩检验分析反向推力量表评分，评估了 35 名患者（27 名 RCD 和 8 名 LCD）之间的时间进程差异。结果-在 156 名患者（9.4%）中观察到 PB。 RCD 患者（556 例中的 97 例 [17.4%]）的 PB 患病率显着高于 LCD 患者（599 例中的 57 例 [9.5%]）；风险比为1.83（95% CI，1.35-2.49）。对数秩检验表明，RCD患者的恢复速度明显慢于LCD患者（P=0.027）。结论：RCD患者出现PB的数量高于LCD患者。 RCD 患者的 PB 恢复时间比 LCD 患者更长。 （中风。2012；43：1654-1656。）
Background and Purpose-The aim of this study was to determine if side of cerebral hemisphere lesion affects the prevalence and time course of pushing behavior (PB) after stroke.Methods-A total of 1660 patients with acute stroke were investigated. PB was assessed using the standardized Scale for Contraversive Pushing. Risk ratios were used to evaluate the differences in the prevalence of PB between right cerebral hemisphere-damaged (RCD) and left cerebral hemisphere-damaged (LCD) patients. The differences in the time course among 35 (27 RCD and 8 LCD) patients were evaluated by analyzing Scale for Contraversive Pushing scores with the Kaplan-Meier method using a log-rank test.Results-PB was observed in 156 (9.4%) patients. The prevalence of PB was significantly higher in RCD (97 of 556 [17.4%]) than in LCD (57 of 599 [9.5%]) patients; risk ratio was 1.83 (95% CI, 1.35-2.49). The log-rank test indicated that RCD patients exhibited a significantly slower recovery than LCD patients (P=0.027).Conclusions-The number of RCD patients who exhibited PB was higher than that of LCD patients. The duration of recovery from PB was longer in RCD patients than in LCD patients. (Stroke. 2012;43:1654-1656.)
