Question
is the chiropractic method used to prevent or treat illness

Answer
Katie,

I am not sure what you mean by "the chiropractic method" (there is no particular technique called "the chiropractic method"), and I am not familiar with any peer-reviewed research that would indicate that chiropractic manipulation is prophylactic for any particular illness.

In my practice, I treat non-surgical musculoskeletal problems with a variety of chiropractic manipulative techniques. These may involve spinal or joint mobilization or manipulation, soft tissue or muscular manipulation, or combinations of both, depending upon the problem. I may also recommend specific rehabilitative exercises for the patient and discuss ergonomic modifications to assist the patient in reducing repetitive trauma to the affected region.

Thank you for your question.
