070- Dr. Alice Cade – Chiropractic, Eye Tracking and Mild Traumatic Brain Injury

In this interview, Dr Alice Cade discusses her interests of eye function and chiropractic amongst other topics. Dr. Cade is a clinician-scientist and senior lecturer at the New Zealand College of Chiropractic, with adjunct appointments in neuroscience research and teaching at the University of Auckland and the Scotland College of Chiropractic. Her research centers on how spinal function and dysfunction influence oculomotor control, multisensory integration, and neuroplasticity, particularly in the context of mild traumatic brain injury (mTBI). Alice’s doctoral work used computerized eye tracking to examine visual markers of concussion, and her ongoing studies explore how spinal care may alter visual attention, eye tracking, and sensorimotor performance in both clinical and subclinical populations.

With a strong interest in translational science, Alice integrates VR-based behavioural testing, eye tracking, and chiropractic care to better understand brain-body interactions and to develop accessible, non-invasive tools for identifying and monitoring neurological dysfunction. She has presented this work to chiropractic, neuroscience, and vision science communities internationally and remains committed to advancing interdisciplinary, clinically meaningful research that strengthens both patient care and the profession’s scientific foundation.

067- Dr. Caroline Fagundes Discusses Vertebral Artery Strain, Posture and Falls

Dr. Caroline Fagundes and I discuss vertebral artery strain, posture and falls in this episode of the chiropractic science podcast. Dr. Fagundes always knew that her professional field would be in healthcare, and when she read about chiropractic, there were no doubts about which profession to choose. She graduated from chiropractic school in 2008 but continued to seek answers, which led her to a graduate degree in kinesiology at the Federal University of Rio Grande do Sul (Brazil).  This is where she also had her first contact with the research of Professor Walter Herzog.

In 2017, she was awarded a scholarship for the Master’s Degree in Cultural Diversity and Social Inclusion, in the area of Health and Social Inclusion – Aging. Her research was about the relationship between static posture and falls in elderly. In her PhD, also carried out with a scholarship, she continued to study this relationship and in 2021 she was awarded a scholarship to study abroad. Dr. Fagundes embarked on a trip to Calgary, Canada in September to study the strain caused in the vertebral artery during cervical movements and cSMT with Professor Herzog. She returned to Brazil in February 2022, and then finished her PhD and currently works as a chiropractor and acupuncturist in her own office in the South of Brazil.

062- Dr. Lindsay Gorrell Discusses Spinal Manipulation, the Vertebral Artery, Reporting of Adverse Events

Dr. Lindsay Gorrell and I discuss her research regarding spinal manipulation, the vertebral artery and reporting of adverse events. Lindsay Gorrell completed her clinical training in Chiropractic and a Master of Research (The effect of manual and instrument applied cervical spine manipulation on mechanical neck pain) at Macquarie University, Australia. She then completed a PhD (Musculoskeletal Biomechanical and Electromyographical Responses Associated with Spinal Manipulation) under the supervision of Drs Walter Herzog and Jay Triano at The University of Calgary, Canada. She is now working as an International Research Fellow at the Balgrist University Hospital, University of Zurich, Switzerland. Lindsay is also studying a Master of Science in Medical Education at The University of Oxford, England.

Lindsay’s research interests are centered on investigating: i) the delivery of spinal manipulation; ii) the physiological responses and clinical outcomes occurring in response to spinal manipulation; and iii) the safety of the manual therapy. This requires different experimental approaches depending on the research question of interest. Most recently, she has published on the relationship between the amount of strain experienced by the vertebral artery, the 3D movements of the head and neck and the forces applied by clinicians during cervical spine manipulation and physiological responses to cervical and upper thoracic spinal manipulation. Lindsay has maintained part-time clinical practice since graduation.

052- Dr. Ken Weber Discusses Advanced MRI Techniques, Pain & Manual Therapy

Dr. Ken Weber

Dr. Ken Weber and I discuss his research pursuits which involve: 1) developing imaging modalities that are more sensitive and specific to the pathology, providing more diagnostic, prognostic, and predictive information; 2) providing more quantitative information to the clinician; and 3) using these measures to better understand the nervous system and how it functions, the neurophysiology of pain, how treatments work, and why certain treatments work for some patients but not for others. Dr. Ken Weber is an Instructor in the Department of Anesthesia, Perioperative and Pain Medicine at Stanford University. He obtained his Doctor of Chiropractic from Palmer College of Chiropractic Florida in 2009 and then completed a PhD in neuroscience at Northwestern University in 2016, specializing in movement and rehabilitation science. Ken’s research intersects clinical pain research and advanced MRI techniques with an emphasis on brain, spinal cord, and musculoskeletal imaging. His research aims to better understand the neural and musculoskeletal changes underlying clinical pain conditions, the mechanisms of treatments, and predictors for recovery. Ken is currently supported by a K23 Mentored Patient-Oriented Research Career Development Award from the National Institute of Neurological Disorders and Stroke of the National Institutes of Health. His previous funding has included the National Center for Complementary and Integrative Health, the National Institute on Drug Abuse, and the NCMIC Foundation, Inc.
