After the patient is free of pain, he is manipulated and told to return and see the therapist after two to four weeks. He is then examined and if he needs further manipulation, this is done and he is called again for further treatment after two to three weeks. This process continues until the patient's spine is perfectly aligned. The patient is called back for a check-up every three months until the therapist is satisfied that the spine is aligned and is likely to stay in place.
