[Purpose] The purpose of the present study was to examine the effects of progressive body weight supported treadmill forward and backward walking training (PBWSTFBWT), progressive body weight supported treadmill forward walking training (PBWSTFWT), progressive body weight supported treadmill backward walking training (PBWSTBWT), on stroke patients' affected side lower extremity's walking ability. [Subjects and Methods] A total of 36 chronic stroke patients were divided into three groups with 12 subjects in each group. Each of the groups performed one of the progressive body weight supported treadmill training methods for 30 minute, six times per week for three weeks, and then received general physical therapy without any other intervention until the follow-up tests. For the assessment of the affected side lower extremity's walking ability, step length of the affected side, stance phase of the affected side, swing phase of the affected side, single support of the affected side, and step time of the affected side were measured using optogait and the symmetry index. [Results] In the within group comparisons, all the three groups showed significant differences between before and after the intervention and in the comparison of the three groups, the PBWSTFBWT group showed more significant differences in all of the assessed items than the other two groups. [Conclusion] In the present study progressive body weight supported treadmill training was performed in an environment in which the subjects were actually walked, and PBWSTFBWT was more effective at efficiently training stroke patients' affected side lower extremity's walking ability.
[目的]本研究旨在探讨渐进式减重平板步行前向和后向行走训练（PBWSTFBWT）、渐进式减重平板步行前向行走训练（PBWSTFWT）、渐进式减重平板步行后向行走训练（PBWSTBWT）对脑卒中患者患侧下肢步行能力的影响。[对象与方法]选取36例慢性脑卒中患者，分为3组，每组12例。每组采用一种渐进式减重平板步行训练方法，每次训练30分钟，每周6次，共训练3周，然后接受常规物理治疗，无其他干预措施，直至进行随访测试。采用Optogait和对称指数测量患侧下肢的步长、支撑相、摆动相、单支撑和步时，以评估患侧下肢的步行能力。[结果]组内比较，3组干预前后均有显著差异；3组间比较，PBWSTFBWT组在所有评估项目上的差异均比其他两组更显著。[结论]本研究在受试者实际行走的环境中进行渐进式减重平板步行训练，PBWSTFBWT在有效训练脑卒中患者患侧下肢步行能力方面更有效。
