Dr. Chadwick was appointed to ISTM as a Lecturer in Biomedical Engineering in September 2012, and leads two modules in the area of medical technology and devices. His research interests are in the application of biomechanical modelling and simulation techniques to the study of upper limb function in a range of neuromuscular disorders including spinal cord injury and stroke. He has a particular interest in the use of functional electrical stimulation (FES) for the restoration of function and in the development of FES devices.

Dr. Chadwick completed his PhD in Bioengineering at Strathclyde University in 1999, after obtaining a degree in Mechanical Engineering at the University of Nottingham. He taught Biomechanics at Aberystwyth University for three years, and spent a numbers of years as a Senior Research Associate at Case Western Reserve University in Cleveland, Ohio, and at the Delft University of Technology in the Netherlands. He is currently the Chair of the International Shoulder Group, a Technical Group of the International Society of Biomechanics.

The goal of my research is to facilitate restoration of function in people with movement disorders of the upper limb following stroke, spinal cord injury and other neuromuscular conditions. The restoration of function can allow the resumption of independent living, the maintenance of health through exercise and the reduction of pain and discomfort. My areas of expertise are in shoulder biomechanics, modelling and simulation of movement, human movement analysis, and the use of Functional Electrical Stimulation for the restoration of arm function. 

One of my main areas of research currently is the development of real-time models for the simulation of arm function. A musculoskeletal model of the upper limb that can simulate the dynamics of the human arm in real time allows the creation of a realistic 'virtual arm'. This can be used as a replacement for the real arm in the development and testing of advanced neural prosthesis systems for the restoration of function in conditions such as high-level spinal cord injury. This allows rapid development and extensive testing of complex devices whilst reducing the burden on human participants. See 'Publications' for more information.

Alongside the development of assistive technologies, I am interested in understanding more about the normal and pathological function of the upper limb musculoskeletal system, and the shoulder in particular. As such, part of my work also attempts to apply the modelling and simulation tools that we develop to understanding more about shoulder function and stability, both in terms of the glenohumeral joint and control of the scapula. We are currently undertaking work to quantify the stability of the glenohumeral joint in post-traumatic injury and following stroke.

My previous research has included: modelling of the shoulder, elbow and wrist for the estimation of muscle and joint loading during daily tasks; computer-assisted surgical planning; analysis of shoulder arthroplasty; modelling of scapular neck fracture; function of the rotator cuff; tendon transfer in rotator cuff pathology; development of strain-gauged force transducers; and the biomechanics of knife stab attacks.
