Fifty patients with MRI-confirmed cervical disk herniations, with accompanying arm pain, received a course of spinal manipulation. After two weeks, 55% reported improvement. At one month, 69% reported improvement and the total rose to 86% after three months. Researchers also documented statistically significant decreases in neck pain, arm pain, and disability. This study supports the use of spinal manipulation for cervical disk injuries.
