Dr. Heidi Haavik is back on the podcast for the second time in today’s episode. With a PhD in neurophysiology, Dr. Haavik is one of the most renowned researchers in chiropractic and is also the Founder of Haavik Research. During the episode, she discusses the latest research in chiropractic (including the most cutting-edge studies), how the research is catching up with the long-appreciated benefits of chiropractic care, and why it’s such an incredible time to be in this industry. In this episode: How chiropractic care changes the brain through nervous system safety. What is now being measured in real time and how it impacts the patient experience. How touch supports the body in learning to be in a regulatory state. What your team can do to support patients so they feel seen and heard. What the recent research is saying about chiropractic and the immune system. Why it’s such an exciting time to be a chiropractor right now. How our bodies protect us from overwhelming stress (and how chiropractic helps). How an adjustment can impact the salience network depending on your state. Why some chiropractors might refuse to embrace this model of care. The ways Dr. Haavik’s perspective on chiropractic has changed over time. The limiting beliefs prevalent in the industry and how they’re shifting now. How the positive outcomes of an adjustment are being strengthened through research. The difference that regular, long-term chiropractic care can make (versus intermittent). The cutting edge research bio-engineers are doing right now related to muscle testing. Ideal changes that could be made to the way patient records are handled today.
