The effect of custom-made orthotics on foot muscle activity**

足部矫形术可以减少行走相关的伤害，重新调整骨骼力学，提高舒适性，缓解膝骨性骨关节炎疼痛。然而，关于矫形器干预如何影响行走过程中的腿部肌肉，人们知之甚少。特别是，矫形器干预可能会影响行走和跑步过程中固有足部肌肉的功能：这主要是由于具有挑战性的测量技术而未被研究的，但正是这些固有足部肌肉与矫形器直接相互作用。该项目将结合一种新的方法，非侵入性地量化足部固有肌肉的活动，并测量这些肌肉对不同矫形器设计的反应。该项目将涉及总部位于温哥华的Wiivv公司与西蒙·弗雷泽大学神经肌肉力学实验室的合作。Wiivv公司利用创新的方法将定制的矫形器和鞋类直接提供给客户，后者开创了一系列量化运动过程中肌肉活动的方法。*该项目将为开发一种创新技术提供跳板，该技术可以帮助一家加拿大公司优化新产品的设计，该公司有可能改善加拿大人的生活质量。此外，从对足部肌肉功能的洞察中获得的基本知识将提高科学界对肌肉功能在运动过程中结构和功能生物力学中的重要性的理解。

Foot orthotics can reduce walking-related injuries, realign the skeletal mechanics, improve comfort and relieve osteoarthritic knee pain. However, not much is known about how orthotic interventions influence the lower limb muscle during walking. In particular, an orthotic intervention is likely to influence the function of the intrinsic foot muscles during walking and running: this has not been investigated primarily due to challenging measurement techniques but it is these intrinsic foot muscles that interact directly with the orthotics. This project will combine a novel approach to non-invasively quantify the activity from the intrinsic foot muscles and to measure the response of these muscles to different orthotic designs. The project will involve the collaboration of Wiivv, a Vancouver-based company that leverages innovative approach to deliver custom orthotics and footwear direct to customers, with the Neuromuscular Mechanics Laboratory at Simon Fraser University that has pioneered a range of approaches for quantifying activity from the muscles during locomotion.****This project will provide a stepping-stone towards the development of an innovative technique that can help optimise the design of novel products by a Canadian company that has the potential to improve the quality of life for Canadians. In addition, the fundamental knowledge gained from insights into the function of the foot muscles will improve the scientific community's understanding of the importance of muscle function on the structural and functional biomechanics during movement.**
