[Purpose] Various types of Gait Exercise Assist Robot (GEAR) have been developed recently, some of which have enabled early improvement in patients with stroke. However, none has yet resulted in independent walking in these patients. Hence, we conducted an exploratory study of the effect of GEAR on achieving independent walking in stroke patients. [Participants and Methods] The participants were 16 patients with severe stroke. We evaluated patients' ability to walk independently after GEAR training. The outcome measure was Stroke Impairment Assessment Set (SIAS) motor score (Hip Flexion, Knee Extension, Foot Pat, Abdominal and Verticality). Differences in five SIAS motor scores were compared between the independent and non-independent walking groups. [Results] There was statistically significant difference between the groups in terms of Verticality among the 5 SIAS items used in the present research . Verticality of SIAS score of 1 was the cut-off value for distinguishing walking independence. [Conclusion] Verticality of SIAS may be a marker of potential walking independence that can be used in rehabilitation plans using walking-assist robots in patients with stroke.
[目的] 近年来已研发出多种类型的步态训练辅助机器人（GEAR），其中一些已使中风患者得到早期改善。然而，尚无一种能让这些患者实现独立行走。因此，我们开展了一项探索性研究，以探究GEAR对中风患者实现独立行走的影响。[参与者与方法] 参与者为16例重度中风患者。我们评估了GEAR训练后患者独立行走的能力。结果指标为中风损伤评估量表（SIAS）运动评分（髋关节屈曲、膝关节伸展、足部拍打、腹部及垂直度）。比较了独立行走组和非独立行走组在五个SIAS运动评分上的差异。[结果] 在本研究使用的5个SIAS项目中，两组在垂直度方面存在统计学显著差异。SIAS评分为1时的垂直度是区分行走独立性的临界值。[结论] SIAS的垂直度可能是潜在行走独立性的一个指标，可用于中风患者使用行走辅助机器人的康复计划中。
