That’s not exactly the truth.
Yes, there are plenty of medical practitioners that poorly represent their profession. I’m sure you could easily apply the same logic here to PT, NP, DO, MD, etc.
What should be emphasized is that Chiropractic has heavily evolved, like any other healthcare field and there is a high degree of overlap between PT and DC methodologies. So much so, PT has lobbied for adoption of joint manipulation.
A good DC won’t limit themselves to 5 minutes visits for a quick adjustment. A good DC is evidence-based, incorporates rehab and education, and provides care to the body and systems.
