A stroke patient with hemiplegic gait is generally described as being slow and asymmetric. Body weight-supported treadmill training and backward gait training are recent additions to therapeutic gait trainings that may help improve gait in stroke patient with hemiplegic gait. Therefore, we examined the effect of progressive backward body weight-supported treadmill training on gait in chronic stroke patients with hemiplegic gait.
Thirty subjects were divided to the experimental and control groups. The experimental group consisted of 15 patients and underwent progressive backward body weight-supported treadmill training. The control group consisted of 15 patients and underwent general treadmill gait training five times per week, for a total of four weeks. The OptoGait was used to analyze gait kinematics, and the dynamic gait index (DGI) and results of the 6-minute walk test were used as the clinical evaluation indicators. A follow-up test was carried out four weeks later to examine persistence of exercise effects.
The experimental group showed statistically significant results in all dependent variables week four compared to the control group. However, until the eighth week, only the dependent variables, of affected step length (ASL), stride length (SL), and DGI differed significantly between the two groups.
This study verified that progressive bodyweight-supported treadmill training had a positive influence on the temporospatial characteristics of gait and clinical gait evaluation index in chronic stroke patients.
偏瘫步态的中风患者通常表现为行走缓慢且不对称。体重支持式跑步机训练和向后步态训练是近期新增的治疗性步态训练方法，可能有助于改善偏瘫步态中风患者的步态。因此，我们研究了渐进式向后体重支持式跑步机训练对慢性偏瘫步态中风患者步态的影响。
30名受试者被分为实验组和对照组。实验组由15名患者组成，接受渐进式向后体重支持式跑步机训练。对照组由15名患者组成，每周进行5次常规跑步机步态训练，共持续4周。使用OptoGait分析步态运动学，动态步态指数（DGI）和6分钟步行测试结果作为临床评估指标。四周后进行随访测试，以检查运动效果的持续性。
与对照组相比，实验组在第四周时所有因变量均显示出统计学上的显著差异。然而，直到第八周，两组之间仅在患侧步长（ASL）、步幅（SL）和DGI这些因变量上存在显著差异。
本研究证实，渐进式体重支持式跑步机训练对慢性中风患者的步态时空特征和临床步态评估指标有积极影响。
