Here is a generally negative summary on Chiropractic from Ross Pomeroy.
I would only disagree with his conclusion that Chiropractic hurts but doesn’t help with mechanical back problems.
There is no basis for the Chiropractic claim that vertebral subluxations cause disease, and Chiros frequently get into “alternative” forms of medical care, and unfortunately often advocate against vaccines, but they are successful and popular because for some people they provide musculo skeletal pain relief.
Pediatric and preventive Chiro are goofy, and Chiro for job injuries and accidents sometimes is a scam. I had a friend who was a Chiro before he became an allopath and Emergency Physician, and he told me the scam was to milk the accident or worker’s comp insurance with long regimens of frequent manipulation for insured patients. You might say that is always the problem for unethical providers, regardless of their discipline–psych, allopath, chiro, surgical, internal medicine, allergy–you name it.
Manipulation does help. Oseopaths are effective manipulators and I know that what they do can mitigate musculo skeletal discomfort and muscle spasm, pressure therapy, massage, and acupuncture are akin to such manipulation.
I am not so hot on back cracking, and chiros should stay away from the neck because of the vertebral arteries, but manipulation can improve a person’s musculo skeletal condition and reduce muscle spasm. I have a number of colleagues in emergency medicine who trained in osteopathic medicine, and can help people with muscle injuries or malfunction.
As an example of something you might not know, the pain of temporal mandibular joint disorder includes spasm of the pterygoid muscles of mastication:
There are pressure point manipulations that can help people with the terrible pain of muscle spasm of the pterygoids. The pterygoids allow you to move your jaw side to side and are affected by the bruxism of nocturnal teeth grinding and jaw clenching.
As an example–if you have a sore muscle sometime, or a muscle spasm, just put a thumb on the area of soreness and press for 2 minutes.
Massage therapy ring a bell?
