Dr. Samuel Howarth

Dr. Samuel Howarth is an Associate Professor, Director of Human Performance Research and the McMorland Family Research Chair in Mechanobiology at the Canadian Memorial Chiropractic College. He also holds adjunct positions at Ontario Tech University, University of Toronto, University of Guelph and Memorial University of Newfoundland. Dr. Howarth obtained his PhD in kinesiology from the University of Waterloo in 2011, focusing on biomechanics and more specifically related to the spine. His current research is directed toward biomechanical analysis of human movement focusing on functional tasks used in daily life and clinical practice. A fundamental component of this work, and scientific inquiry in general, is measurement and data handling. Once a topic primarily relevant to researchers, the proliferation of low-cost sensors capable of providing clinicians with a seemingly unimaginable amount data extends the conversation on the acquisition and interpretation of measurements to the clinical environment.

Dr. William Reed is an Associate Professor in the School of Health Professions, Department of Physical Therapy at University of Alabama at Birmingham. He is the director of the Mechanisms of Spinal Manual Therapy Laboratory. His research is directed towards determining the peripheral and central mechanisms of spinal manipulation (manual therapy) for the treatment of musculoskeletal pain.  He is also the Interim Co-Director of the PhD program in Rehabilitation Science at the University of Alabama at Birmingham. Here we discuss some of Dr. William Reed’s research starting with his introduction to research as a chiropractic student in 1994 then we’ll discuss his work with Dr. Joel Pickar, his K01 award topic, and progressing to his latest line of research on characterization of a rat LBP model and spinal mobilization mechanisms.

In this episode, Dr. Anthony Lisi and I discuss the state of chiropractic practice and research in the US Veterans Health Administration. Dr. Anthony Lisi is the Chiropractic Program Director for the US Veterans Health Administration, overseeing all national programmatic issues related to the integration of chiropractic clinical services, education and research. He is also an Associate Research Scientist at the Yale Center for Medical Informatics, Yale University School of Medicine.

He has authored numerous peer-reviewed publications on topics including low back pain management, spinal manipulation, interprofessional education, and chiropractic services. Dr. Lisi received the American Chiropractic Associations’ 2015 Academician of the Year award, and the 2017 Chiropractor of the Year award.
