The ability to adapt walking is important for safe ambulation. Assessments of impairments in walking adaptability with the Interactive Walkway may aid in the development of individualized therapy strategies of stroke patients. The Interactive Walkway is an overground walkway with Kinect v2 sensors for a markerless registration of full-body kinematics, which can be augmented with (gait-dependent) visual context to assess walking adaptability. This study aims to evaluate the potential of the Interactive Walkway as a new technology for assessing walking adaptability in stroke patients. 30 stroke patients and 30 controls performed clinical tests, quantitative gait assessments and various walking-adaptability tasks on the Interactive Walkway. Outcome measures were compared between stroke patients and controls to examine known-groups validity. Pearson's correlation coefficients were calculated to assess the relationship between walking-adaptability outcomes and commonly used clinical test scores of walking ability and spatiotemporal gait parameters of unconstrained walking. Good known-groups validity for walking-adaptability outcomes was demonstrated. In addition, the vast majority of walking-adaptability outcomes did not or only moderately correlate with clinical test scores of walking ability and unconstrained walking parameters. Interactive Walkway walking-adaptability outcomes have good known-groups validity and complement standard clinical tests and spatiotemporal gait parameters.IMPLICATIONS FOR REHABILITATIONThe Interactive Walkway allows for a comprehensive walking-adaptability assessment.Good known-groups validity for walking-adaptability tasks was demonstrated and walking-adaptability tasks complemented clinical tests and gait parameters.The Interactive Walkway has potential for monitoring recovery of walking after stroke.Assessments of walking adaptability may contribute to individualized interventions.
适应行走的能力对于安全行走很重要。使用 Interactive Walkway 评估步行适应性障碍可以帮助制定中风患者的个体化治疗策略。Interactive Walkway 是一种地面步道，配备 Kinect v2 传感器，可对全身运动学进行无标记注册，并可通过（依赖步态的）视觉环境来评估步行适应性。本研究旨在评估 Interactive Walkway 作为一种新技术评估中风患者步行适应性的潜力。30 名中风患者和 30 名对照组在 Interactive Walkway 上进行了临床测试、定量步态评估和各种步行适应性任务。将中风患者和对照组的结果进行比较，以检验已知组别的有效性。计算 Pearson 相关系数，以评估步行适应性结果与常用的步行能力临床测试评分以及无约束步行的时空步态参数之间的关系。 步行适应性结果具有良好的已知组间有效性。此外，大多数步行适应性结果与步行能力的临床测试评分和无约束步行参数之间没有相关性或只有中度相关性。Interactive Walkway 步行适应性结果具有良好的已知组间有效性，并补充了标准的临床测试和时空步态参数。
康复应用 Interactive Walkway 允许进行全面的步行适应性评估。 步行适应性任务的已知组间有效性得到了验证，并且这些任务补充了临床测试和步态参数。Interactive Walkway 具有监测中风后行走恢复的潜力。 评估步行适应性可能有助于制定个性化干预措施。
