This project aims to understand the importance of neural control and muscular strength on foot function, and injury mechanics. Recent work has highlighted the importance of muscles within the foot for determining how the foot manages mechanical loads during running. Furthermore, how the foot is loaded during running is a key factor in the development of foot injuries. In particular, stress fractures associated with repeated loading of foot bones are a significant problem for a broad range of populations, from the millions of recreational runners in the UK, to the UK's military recruits in training. To date, no research has investigated the probable link between neuromuscular function of foot and ankle muscles, with foot bone loading and injury during running.The project is highly multidisciplinary and will draw on the supervisory team's combined expertise to provide a unique approach for investigating foot injury mechanics. The project is expected to include the following:1. Initial experiments will combine advanced electromyography techniques with motion capture and gait analysis methods to acquire experimental measures of muscle function and lower limb mechanics in-vivo. Imaging techniques (MRI and ultrasound) will also be applied to attain person-specific measures of muscle size and physiological characteristics.2. A neuromuscular model will be developed using experimental data and subject-specific muscle parameters. The model will be used to estimate muscle forces that cannot be measured, and predict the effects of changes to muscle parameters on muscle forces and foot load management.From this we can develop targeted interventions to strengthen appropriate muscles in an effort to reduce injury risk in relevant populations, and improve capacity for gait in those with impaired function. Fundamental knowledge of foot neuromuscular and mechanical function might also drive design of artificial limbs for prosthetics and robotics.

本项目旨在了解神经控制和肌肉力量对足部功能的重要性，以及损伤力学。最近的研究强调了足部肌肉在跑步过程中决定足部如何管理机械负荷的重要性。此外，在跑步过程中足部如何承受负荷是足部损伤发展的关键因素。特别是，与足部骨骼的重复负荷相关的应力性骨折对于从英国数百万休闲跑步者到英国训练中的新兵的广泛人群来说是一个重大问题。到目前为止，还没有研究调查足部和踝关节肌肉的神经肌肉功能之间的可能联系，与足部骨骼负荷和跑步过程中的损伤。该项目是高度多学科的，将借鉴监督团队的综合专业知识，为研究足部损伤力学提供一种独特的方法。该项目预计将包括以下内容：1。初步实验将结合联合收割机先进的肌电图技术与运动捕捉和步态分析方法，以获得肌肉功能和下肢力学在体内的实验措施。成像技术（MRI和超声波）也将被应用于获得肌肉大小和生理特征的个人特定措施。将使用实验数据和受试者特定的肌肉参数开发神经肌肉模型。该模型将用于估计无法测量的肌肉力量，并预测肌肉参数变化对肌肉力量和足部负荷管理的影响。据此，我们可以制定有针对性的干预措施，以加强适当的肌肉，从而降低相关人群的受伤风险，并改善功能受损人群的步态能力。足部神经肌肉和机械功能的基础知识也可能推动假肢和机器人假肢的设计。
