His team have unique expertise in using an innovative combination of modern imaging techniques that include X-Ray video, MRI and ultrasound for studying in vivo muscle-tendon and joint function and mechanical parameters such as moment arms. This allows the development of accurate and subject-specific biomechanical models of the musculoskeletal system to study joint and muscle forces and the loading of different tissues during various movements and sports activities.
They are the only group in the world that combined isokinetic dynamometry with X-Ray video to examine knee joint and muscle in-vivo function in both static and dynamic conditions.
He has written various book chapters on Skeletal muscle function, Muscle Strength and Isokinetic Dynamometry including the Isokinetic Dynamometry section in the book Biomechanical Evaluation of Movement in Sport and Exercise (Routledge), and the chapter on Isokinetic Dynamometry in the 1992 (first) and 1997 editions of the Biomechanical Analysis in Sport and Exercise Guidelines of the British Association of Sports and Exercise Sciences (BASES).
He was also the organiser of the first Isokinetic Dynamometry Workshop in 1992 and all the subsequent BASES Isokinetic Dynamometry Workshops in 1998, 2000, 2006 and 2009 and the lead author of the recent BASES Expert Statement on Measurement of Muscle Strength with Isokinetic Dynamometry (http://www.bases.org.uk/About/BASES-Expert-Statements/Measurement-of-Muscle).
He has published over 100 journal papers with a citation index of ~4000 and an h-index of 39:http://scholar.google.co.uk/citations?user=WEC96BMAAAAJ&hl=en
