Chiropractic adjustment or manipulation is a manual procedure that utilizes the highly refined skills developed during four intensive years of chiropractic education. The chiropractor typically uses his/her hands to manipulate the joints of the body, particularly the spine, in order to reduce pain, and restore or enhance joint function.
Chiropractic manipulation is a highly controlled procedure that rarely causes discomfort. The chiropractor adapts the procedure to meet the specific needs of each patient.1
