目的：为了确定主观视觉垂直（SVV）的误解是否是偏瘫患者平衡困难的基础。设计：描述性研究，使用方便样本。设置：一所大学医院的物理医学部。参与者：30名在前3个月半球卒中后偏瘫的住院患者。干预措施：不适用。主要结果测量：测试SVV时，受试者坐在一个黑暗的房间里，并被要求调整发光线的垂直位置。计算8次试验的平均SVV偏差和不确定度（定义为标准偏差）。平衡通过卒中姿势评估量表（PASS）进行评估，同时患者坐在放置在Satel力平台上的横向摇摆平台上。记录平均体位和不稳定评分（Lx），计算为压力中心的行程长度。结果：30例患者中有20例记录到异常SVV。平衡（PASS、Lx）和平衡度（Lx）与SVV倾斜显著相关（P
Objective: To determine whether misperception of the subjective visual vertical (SVV) underlies balance difficulties in hemiplegic patients.Design: Descriptive study, using a convenience sample.Setting: Department of physical medicine of a university hospital.Participants: Thirty inpatients with hemiplegia after a hemispheric stroke during the 3 previous months.Interventions: Not applicable.Main Outcome Measures: The SVV was tested while subjects sat in a dark room and were asked to adjust a luminous line to the vertical position. Mean SVV deviation and uncertainty, defined as the standard deviation, were calculated for 8 trials. Balance was assessed by the Postural Assessment Scale for Stroke (PASS) and while patients sat on a laterally rocking platform placed on a Satel force platform. The mean body position and the instability score (Lx), calculated as the length of the course of the center of pressure, were recorded. Functional outcome was also evaluated by the FIM instrument.Results: An abnormal SVV was recorded for 20 of 30 patients. Balance (ie, PASS, Lx) and FIM correlated significantly with SVV tilt (P
