Visual biofeedback/forceplate systems are often used for treatment of balance disorders. In this study, the researchers investigated whether the addition of visual biofeedback/forceplate training could enhance the effects of other physical therapy interventions on balance and mobility following stroke.
The study included a sample of convenience of 13 outpatients with hemiplegia who ranged in age from 30 to 77 years (mean=60.4, SD=15.4) and were 15 to 538 days poststroke.
Subjects were assigned randomly to either an experimental group or a control group when the study began, and their cognitive and visual-perceptual skills were tested by a psychologist. Subjects were also assessed using the Berg Balance Scale and the Timed "Up & Go" Test before and after 4 weeks of physical therapy. Both groups received physical therapy interventions designed to improve balance and mobility 2 to 3 times per week. The experimental group trained on the NeuroCom Balance Master for 15 minutes of each 50-minute treatment session. The control group received other physical therapy for 50 minutes.
Following intervention, both groups scored higher on the Berg Balance Scale and required less time to perform the Timed "Up & Go" Test. These improvements corresponded to increased independence of balance and mobility in the study population. However, a comparison of mean changes revealed no differences between groups.
Although both groups demonstrated improvement following 4 weeks of physical therapy interventions, no additional effects were found in the group that received visual biofeedback/forceplate training combined with other physical therapy.
视觉生物反馈/测力台系统常用于平衡障碍的治疗。在本研究中，研究人员调查了增加视觉生物反馈/测力台训练是否能增强其他物理治疗干预对中风后平衡和移动能力的影响。
本研究纳入了13名偏瘫门诊患者的便利样本，年龄在30至77岁之间（平均=60.4，标准差=15.4），中风后15至538天。
研究开始时，受试者被随机分配到实验组或对照组，由一名心理学家测试他们的认知和视觉感知技能。在进行4周物理治疗前后，还使用伯格平衡量表和定时“起立-行走”测试对受试者进行评估。两组均接受旨在改善平衡和移动能力的物理治疗干预，每周2至3次。实验组在每次50分钟的治疗过程中，在NeuroCom Balance Master上训练15分钟。对照组接受50分钟的其他物理治疗。
干预后，两组在伯格平衡量表上的得分均更高，完成定时“起立-行走”测试所需时间更少。这些改善与研究人群中平衡和移动能力的独立性增加相对应。然而，平均变化的比较显示两组之间没有差异。
尽管两组在进行4周物理治疗干预后均有改善，但在接受视觉生物反馈/测力台训练与其他物理治疗相结合的组中未发现额外效果。
