Dr Martinez-Valdes is an Associate Professor in Musculoskeletal Physiotherapy and Clinical Neuromechanics. He leads the Clinical Neuromechanics Laboratory, where he uses electrophysiology and imaging to understand how fatigue, ageing, pain and injury alter motor function, and to translate those findings into targeted rehabilitation.

Biography

Dr Eduardo Martinez-Valdes is an Associate Professor in Musculoskeletal Physiotherapy and Clinical Neuromechanics at the University of Birmingham’s School of Sport, Exercise and Rehabilitation Sciences. His research explores the neuromuscular control of human movement, with a specific focus on motor unit behaviour, tendon mechanics, and pain-related adaptations in both healthy and clinical populations. He is internationally recognised for his innovative use of high-density surface electromyography to uncover the neural strategies behind motor performance, learning, and rehabilitation.

Bridging basic and applied science, Dr Martinez-Valdes investigates how musculoskeletal pain, tendon pathology, ageing, and neurological conditions alter motor unit recruitment and firing behaviour. A central aim of his work is translating these advanced neuromechanical measurements into clinically meaningful insights that refine rehabilitation practices and enhance patient outcomes.

A prolific scholar, he has authored over 90 peer-reviewed articles. He serves on the editorial boards of the Journal of Electromyography and Kinesiology and the Journal of Applied Physiology, and is an elected council member of the International Society of Electrophysiology and Kinesiology (ISEK). His research is supported by leading organisations, including Orthopaedic Research UK, Muscular Dystrophy UK, The Physiological Society, and ANID.

In addition to his research, Dr Martinez-Valdes leads and contributes to training programmes in human physiology, exercise science, and neuromechanical research methods. He collaborates widely with clinicians and international research groups and is committed to interdisciplinary approaches that bridge neurophysiology, biomechanics, and clinical practice.
