Biographical details

Associate Professor Ginn is a musculoskeletal anatomist in the Discipline of Biomedical Science, Sydney Medical School, University of Sydney. She teaches functional, applied anatomy to various health professional groups and is a musculoskeletal physiotherapist in part time private practice. She is involved in research related to the assessment and treatment of shoulder dysfunction evaluating the validity and reliability of components of the physical examination of the shoulder. She has over 30 publications in such journals as Journal of Orthopaedic Research, Medicine and Science in Sport and Exercise, Physical Therapy, Journal of Science and Medicine in Sport, Journal of Rehabilitation Medicine and Journal of Electromyography and Kinesiology, Clinical Anatomy. She is regularly invited to present at conferences both nationally and internationally and is a Visiting Professor at the University of Gothenburg, Sweden and an Honorary Research Associate at the Royal National Orthopaedic Hospital, London, United Kingdom. She is currently a member of the Board of the International Congress of Shoulder and Elbow Therapists.
