Gait (walking or running) is a fundamental component of human physical function. However, gait patterns are not stable over time, and can change due to alterations in the structure and function of muscles, bones, or our senses over time. Importantly, voluntary changes to our gait patterns - termed gait modifications - may be necessary in response to, or in advance of, these structural and functional changes in an effort to optimize overall physical function. Our research group has been established as leaders in gait modification research. Our recent research has shown that changing specific aspects of one's gait pattern can have predictable effects elsewhere. For example, modifying how one places their foot when it contacts the ground can change what happens at the knee or hip. We have also conducted research showing what happens if the amount or timing of activation of specific muscles is changed. While the knowledge of the effects of gait modification has advanced greatly in recent years, most gait modification research and practice is confined to laboratory settings. Therefore, how these changes are transferred into real-world, everyday activities is not known. The short-term objectives of the proposed research are to address this very important gap in our knowledge. Our work will capitalize on recent advances in the tracking of movement using wearable technology; this includes our custom-designed shoe system that can monitor foot movements in real-world settings, as well as provide sensory cues required for movement retraining in real-time. Our overall working framework is that how one immediately performs a modified gait pattern in a laboratory setting is not the same as performance in the "real world", and will change over time. Therefore, we do not have a full picture of how movement modification is delivered and performed in everyday life. We aim to probe this through research that combines aspects of movement analysis and training, and innovative wearable technology. People's interest in their own movement and mobility has skyrocketed in recent years, driven largely by the boom in wearable technology products that track multiple human functions. While these products are capable of measuring certain aspects of movement, they are currently unable to easily provide targeted feedback or direct training to change movement, if desired. Our proposed research will provide researchers, clinicians and coaches, industry, and the general public with novel approaches and knowledge to address this, thus permitting people to ultimately take control of their movement performance and modify key characteristics to improve function.

步态（步行或跑步）是人类身体机能的基本组成部分。但是，随着时间的流逝，步态模式并不稳定，并且由于肌肉，骨骼或我们的感觉随着时间而变化而变化。重要的是，对于我们的步态模式（称为步态修改）的自愿变化可能是对这些结构和功能变化的响应，以优化整体物理功能。我们的研究小组已成为步态修改研究领域的领导者。我们最近的研究表明，改变步态模式的特定方面可以在其他地方产生可预测的影响。例如，修改脚接触地面时如何放置脚可以改变膝盖或臀部发生的事情。我们还进行了研究表明，如果改变了特定肌肉的激活数量或时机会发生什么。尽管近年来对步态修改影响的知识已经大大提高，但大多数步态修改研究和实践都局限于实验室环境。因此，这些变化如何转移到现实世界中，日常活动尚不清楚。拟议研究的短期目标是解决我们知识的这一非常重要的差距。我们的工作将利用使用可穿戴技术跟踪运动的最新进展；这包括我们定制设计的鞋系统，该系统可以监视现实世界中的脚部运动，并提供实时移动重新训练所需的感官提示。我们的整体工作框架是，一个人如何在实验室环境中立即执行修改的步态模式与“现实世界”中的性能不同，并且会随着时间的推移而改变。因此，我们没有关于如何在日常生活中交付和执行运动修改的全面了解。我们旨在通过结合运动分析和培训方面的研究以及创新的可穿戴技术来探究这一点。近年来，人们对自己的运动和机动性的兴趣激增，这主要是由于追踪多个人类功能的可穿戴技术产品的繁荣。尽管这些产品能够衡量运动的某些方面，但目前，如果需要，它们目前无法轻松提供针对性的反馈或直接培训以改变运动。我们提出的研究将为研究人员，临床医生和教练，行业和公众提供新的方法和知识来解决这一问题，从而使人们最终控制其运动绩效并修改关键特征以提高功能。
