Visual cue deprivation is the instability of head control is increased. The purpose of this study is to investigate the effects of visual cue deprivation balance training by applying head control feedback to the balance and gait ability of stroke patients. The study was conducted on 41 patients diagnosed with hemiplegia due to stroke. Subjects were randomly assigned to any of the following groups: the experimental group I, the experimental group II or the control group. The randomization method used a simple randomization method. To evaluate changes in balance function, a LOS (Limit of Stability) and a BBS (Berg Balance Scale) were performed. In addition, to evaluate changes in ST (stride time), SL (stride length), and cadence, a LEGSys were performed. A two-way repeated ANOVA was conducted to analyze the differences between groups. There were significant differences between groups in all variables for the balance function. There were significant differences between groups in all variables for the balance function. There were significant differences between groups in SL and cadence for the gait function. Visual cue deprivation balance training applying head control feedback is effective in improving dynamic balance ability and cadence. It is necessary to constantly maintain the head orientation by feedback and to properly control the head movement.
视觉提示剥夺会增加头部控制的不稳定性。本研究旨在通过对头控反馈应用于平衡和步态能力，来探讨视觉提示剥夺平衡训练对脑卒中患者的影响。研究对象为 41 名因脑卒中而导致偏瘫的患者。将受试者随机分为以下三组：实验组 I、实验组 II 或对照组。使用简单随机化方法进行随机分组。为了评估平衡功能的变化，进行了 LOS（稳定性极限）和 BBS（伯格平衡量表）测试。此外，为了评估 ST（步长时间）、SL（步长）和步频的变化，进行了 LEGSys 测试。采用双向重复方差分析比较组间差异。平衡功能的所有变量在组间均存在显著差异。步态功能的 SL 和步频在组间也存在显著差异。应用头控反馈的视觉提示剥夺平衡训练可有效提高动态平衡能力和步频。通过反馈不断保持头部方向，并适当控制头部运动是必要的。
