The purpose of this study was to determine the effect of combining electrogoniometric feedback with contemporary physical therapy procedures for treatment of genu recurvatum following stroke. Twenty-six patients suffering knee hyperextension resulting from cerebrovascular disorders were allocated to either a control group or an experimental group. Both groups received treatment for knee hyperextension during two consecutive phases. During phase I the control group received physical therapy and the experimental group received electrogoniometric feedback as an adjunct to physical therapy. In phase II both groups received physical therapy alone. Each phase lasted four weeks, during which time patients were treated 45 minutes daily, five days every week. Subjects in the experimental group showed greater reduction in knee hyperextension. This was particularly evident in phase II when the difference between groups for reduction in knee hyperextension reached statistical significance (U = 40, p = 0.011). These results suggest that the addition of electrogoniometric feedback to standard physical therapy enhanced the effectiveness of treatment for genu recurvatum in stroke.
本研究的目的是确定将电子测角反馈与当代物理治疗程序相结合对中风后膝反张的治疗效果。26例因脑血管疾病导致膝关节过伸的患者被分配到对照组或实验组。两组在连续两个阶段接受膝关节过伸治疗。在第一阶段，对照组接受物理治疗，实验组接受电子测角反馈作为物理治疗的辅助手段。在第二阶段，两组均仅接受物理治疗。每个阶段持续四周，在此期间患者每天接受45分钟治疗，每周治疗五天。实验组的受试者膝关节过伸程度有更大程度的减轻。这在第二阶段尤为明显，此时两组在膝关节过伸减轻程度上的差异达到统计学显著性（U = 40，p = 0.011）。这些结果表明，在标准物理治疗中添加电子测角反馈可提高中风后膝反张的治疗效果。
