I attended Michael Shacklock’s Upper and Lower Quarter Neurodynamics course in Spring of 2018 and it was one of those seminars that completely changed the way I looked at my patients on Monday morning. Michael presented for four days on some awesome ways we can test to see if a patient has a neuro component to their symptoms.

Surprisingly many conditions that have a partial neuro aspect don’t require radiation or pins/ needles!

Here’s a few types of cases I’ve found neuro aspects within (at least a percentage):

  • Subacromial Impingement Cases
  • Ankle injury diagnosed in the training room as a deltoid ligament grade 1
  • Medial Epicondylitis

These types of cases would have fallen through the cracks in my eval and I would have been treated them as pure musculoskeletal conditions, but the truth is when I implemented some corrected to the neuro findings, the person improved past that plateau we sometimes find in patient care.

I feel very fortunate to have Michael on to share some wisdom with the rest of the sports medicine listeners.


  • Spinal cord movement is a looking glass into lumbar nerve root behavior
  • There’s a 66% reduction in spinal cord movement with disc protrusions
  • Flexion will open the foramen and reduce pressure on the nerve
  • Across joints the nerve is more extensible, unrelated to amount of connective tissue


Michael Shacklock: Michael received his graduate qualification at the Auckland School of Physiotherapy, New Zealand, in 1980.  He worked in public hospitals in the medical, surgical, paediatrics, orthopaedics, geriatrics, intensive care and burns areas around New Zealand before being employed in private practices, treating spinal and sports injuries in Nelson with Michael Monaghan and Auckland with Margaret Franklin.  In 1985 he moved to Adelaide, Australia, working at the Royal Adelaide Hospital and private practices around Adelaide. He completed a Graduate Diploma in Advanced Manipulative Therapy in 1989 and converted this to a Masters degree at the University of South Australia in 1993. He was awarded a Fellow of the Australian College of Physiotherapists (Australian Physiotherapy Association) for his monograph and international best-seller text book, Clinical Neurodynamics, Elsevier, Oxford, 2005.  In addition to his neurodynamics book, he has published two other books, Moving in on Pain (Elsevier) and Biomechanics of the Nervous System: Breig Revisited.  He also authored, co-authored and mentored numerous research studies, editorials, commentaries and clinical papers in international peer reviewed journals articles which have garnered many international awards, including Visiting Professor of the Faculty of Medicine, Barcelo University, Buenos Aires (see academic activities on ResearchGate).  He was a member of the International Advisory Board of the journal Musculoskeletal Theory and Practice (formerly Manual Therapy), United Kingdom and is an Associate Editor of the Journal of Manual and Manipulative Therapy, USA.  Michael presents keynote addresses and invited conference lectures, trains staff at elite sports medicine facilities and sports clubs, universities, hospitals and private seminars around the world. His special interests are neurodynamics, measurement of mechanical function of the nervous system, pain and the nervous system and musculoskeletal function.  His most valued interest is how to synthesise science and clinical practice using evidence and reasoning. Michael is an active clinician, has 35 years of experience in treating patients and is recognised as an international leader in the diagnosis and treatment of musculoskeletal disorders with a neural aspect.
