What everwilde is talking about is called NUCCA. It is a special discipline of chiroporactic that is very different from standard chiropractic. The neck twist and pop and back popping is definitely not NUCCA.

The NUCCA web site has a find a practitioner link. NUCCA chiros are rare.

The PCS reference in a chiropractor's list of ailments that can be cured or helped should be considered very carefully. There are some symptoms of PCS that can be helped by chiropractic but they are not the brain symptoms. Often, a head injury/concussion will also have an injury to the neck. In some of these neck injuries, chiropractic can help. In some cases of PCS, muscle stress (tension) can also cause problems that can be helped with chiropractic.

Except for the rare NUCCA chiropractor who can correct C1 and C2 subluxations, beware the chiropractor who claims he can heal almost every medical problem. There are plenty who claim this.

I have been an avid chiropractic patient for almost thirty years. I have been mistreated by quite a few chiropractors who claim they can fix almost anything. I have also been treated by chiropractors who are true healers. There can be a vast difference between them.

Here in the Boise, Idaho area, most of the chiropractors practice "chiropractic wellness." This philosophy of care says the patient can only achieve wellness with proper and routine chiropractic care. The cost of this chiropractic care is usually about $800 per year per patient. The odd thing is that Blue Cross (the overwhelming insurer in Idaho) will pay up to $800 per year for chiropractic care.

These chiropractors definitely know how to practice wallet wellness. With enough patients at $800 per year, the only thing that will stay well is the chiropractors' wallet.

I have always had to pay for chiropractic care from my own pocket. As a result, I need to be very careful where my dollars go. I have been treated by 14 different chiropractors. Only three of them were worth the money spent. Our most recent chiropractor just moved out of state. My wife thinks she has just found another good one. We'll see.

FYI,
there are many different chiropractic discilpines:

Palmer
Diversified
Gonstead
Activator
Equalizer
Leg Check (usually a part of Activator)
Thompson
NUCCA
and a mix of the above and osteopathic techniques and physical therapy.

The above range from heavily based in metaphysical philosophy to very science (neuromuscular) based.

So, patient beware.
