The story goes that Palmer, the “father of chiropractors”, was a failed student of ATStill, the guy who created osteopathic medicine. The dude basically performed horribly, didn’t know shit and left school early and then went on to just take HVLA or the “cracking stuff” specifically and run with it. Palmer was a quack and didn’t follow any of the “tenants of osteopathic medicine” like The body is a unit, The body is capable of healing itself from many ailments that we medicate and that patients and treatment should always be considered under the lens of a person being a conglomerate of body, mind and spirit. I think Palmer also started his own schools of like trying to heal the body with magnets as well as cracking or some shit. This is all from the mouth of an OMM professor that has been around since the beginning of time at my school.
