Dr. Kevin Haussler

Dr. Haussler graduated from The Ohio State University, College of Veterinary Medicine in 1988 and completed a small animal internship in Sacramento, CA.  To further his training in the conservative management of spinal-related disorders, he pursued human training at Palmer College of Chiropractic-West and completed a veterinary chiropractic certification program in 1993.  He attended the University of California-Davis to attain a PhD focusing on spinal pathology and pelvic biomechanics in Thoroughbred racehorses.   Currently, he is an Associate Professor at the Orthopaedic Research Center at Colorado State University and is involved in teaching, clinical duties, and research into the objective assessment of musculoskeletal pain, spinal dysfunction and the application of physical therapy and rehabilitation. Please comment below if you have any questions for us during the interview. I might choose some of them for our conversation.


Dr. Brian Anderson and I discuss the article, Where to start? A two stage residual inclusion approach to estimating influence of the initial provider on health care utilization and costs for low back pain in the US (2022). We question the relationship between chiropractic and emergency department – ED visits in this paper. Does it makes sense that those who first saw a chiropractor had the lowest out of pocket and overall costs of care, the least hospitalizations and serious illnesses out of any provider type and yet had the highest emergency department – ED visits? Furthermore, those who first saw a chiropractor ranked second lowest of all providers for early opioid prescription, long opioid prescription, MRI/CT imaging, and surgery.

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.

I’d also like to point out that Ken was recently selected to be part of the CARL (Chiropractic Academy for Research Leadership) program
