How do mechanics, neural drive and muscle architecture interact in muscles? This project will determine how an individual person’s muscle activity, muscle structure and mechanical properties, and the local mechanical conditions around the muscle interact as muscles move and deform, by using experiments and personalised computational models that can examine these factors and their interactions concurrently. To achieve this, we will develop novel magnetic resonance imaging methods to measure the m ....How do mechanics, neural drive and muscle architecture interact in muscles? This project will determine how an individual person’s muscle activity, muscle structure and mechanical properties, and the local mechanical conditions around the muscle interact as muscles move and deform, by using experiments and personalised computational models that can examine these factors and their interactions concurrently. To achieve this, we will develop novel magnetic resonance imaging methods to measure the mechanical properties of muscles in humans and methods for modelling muscles. As well as answering fundamental scientific questions about muscle function, these new techniques will provide a platform for studying other muscles, and for future development of muscle training methods and technologies to optimise muscle function.Read moreRead less
Biomechanics of the human spine measured using magnetic resonance imaging. Statistics show that 80% of the population suffer back pain at some time. However, because the spine is very complex our understanding of its mechanics and the causes of back pain are still limited. This project will investigate the anatomy and activity of the spinal muscles and the behaviour of the intervertebral disc in living subjects using innovative Magnetic Resonance Imaging techniques. Significant outcomes will be ....Biomechanics of the human spine measured using magnetic resonance imaging. Statistics show that 80% of the population suffer back pain at some time. However, because the spine is very complex our understanding of its mechanics and the causes of back pain are still limited. This project will investigate the anatomy and activity of the spinal muscles and the behaviour of the intervertebral disc in living subjects using innovative Magnetic Resonance Imaging techniques. Significant outcomes will be new definitive descriptions of the detailed anatomy of the spine and its mechanisms. This will enhance the accuracy and detail of models under development for predicting spinal function following disease, injury or surgical procedures.Read moreRead less

Intelligent training (iTraining) for the human Achilles tendon. The project aims to improve understanding of the mechanical environment of the Achilles tendon. The Achilles tendon plays a crucial role in human motor function and is also a structure that is commonly injured and notoriously difficult to treat. A major barrier to improving Achilles tendon function, preventing tendon injury and enhancing tendon repair is a poor understanding of the mechanical environment of the Achilles tendon durin ....Intelligent training (iTraining) for the human Achilles tendon. The project aims to improve understanding of the mechanical environment of the Achilles tendon. The Achilles tendon plays a crucial role in human motor function and is also a structure that is commonly injured and notoriously difficult to treat. A major barrier to improving Achilles tendon function, preventing tendon injury and enhancing tendon repair is a poor understanding of the mechanical environment of the Achilles tendon during training and rehabilitation. The project aims to develop a better understanding of the loading conditions that optimise tendon metabolism. Based on this, it then intends to develop new technologies to estimate the mechanical behaviour of the human Achilles tendon in real time based on integrated use of wearable technology, and new training guidelines that will optimise human tendon adaptation.Read moreRead less

High-speed, three-dimensional, x-ray fluoroscopy for accurate measurement of human joint motion. This proposal addresses one of the most difficult and long-standing problems in the field of biomechanics: How can human joint motion be measured accurately and non-invasively during common activities such as walking, stair ambulation and running? Low-dose, high-speed, three-dimensional, x-ray fluoroscopy provides an excellent solution to this problem and, in so doing, can play a pivotal role in heal ....High-speed, three-dimensional, x-ray fluoroscopy for accurate measurement of human joint motion.

Low-dose, high-speed, three-dimensional, x-ray fluoroscopy provides an excellent solution to this problem and, in so doing, can play a pivotal role in healthcare, through clinical gait analysis and gait rehabilitation (diagnosis, prevention and treatment of movement disorders); in sports, through the development of personalized training programs for elite athletes; and in entertainment, through the creation of physics-based animations for the video/digital games industry.Read moreRead less

Summary
Synchrotron-based modelling of the deformation and fracture mechanism in normal and osteoporotic femurs under multiaxial loading cycles. The femur is a light-weight structure designed to best perform in life. However, the complex tissue architecture, microstructural organisation and its complex loading regimens make it difficult to understand how the femur can deform and fracture. This project studies femoral fractures by modelling the proximal femur with a micrometric level of detail. Synchrotr ....Synchrotron-based modelling of the deformation and fracture mechanism in normal and osteoporotic femurs under multiaxial loading cycles. The femur is a light-weight structure designed to best perform in life. However, the complex tissue architecture, microstructural organisation and its complex loading regimens make it difficult to understand how the femur can deform and fracture. This project studies femoral fractures by modelling the proximal femur with a micrometric level of detail. Synchrotron femur images are taken in loaded and unloaded conditions. Cortical strain and fracture are measured, replicating possible multiaxial loads. Micro finite-element models will be used to study the contribution that the bone tissue architecture, tissue structure and activity types make to the fracture. The resulting knowledge will have future orthopaedic applications.Read moreRead less
