Spinal manipulation should only be performed by trained professionals, such as chiropractors. There are some doctors of osteopathy who are qualified to do the procedure, but you should be certain that the person who is treating you is qualified.
To perform a manipulation, the chiropractor should evaluate the patient thoroughly to be sure there are no medical issues that would contraindicate (go against) a spinal manipulation. Once the evaluation is done and the chiropractor knows what he or she wants to do, the patient is placed in the appropriate position for the maneuver.
Using the “treating” hand, the chiropractor places the hand over or under the target vertebrae (spinal bone), using a slow strong force. He or she then thrusts quickly as hard as necessary to make the adjustment.
There may be a popping sound in the joint cavity with the thrust.
