This study will enroll patients with chronic neck pain (more than 3 months duration) with or without occipitally-based head pain and without signs of radiculopathy or myelopathy. They must have pain of at least moderate intensity (by their report and by a score of at least 3 out of 10 on a visual analogue pain scale) on at least four days out of a week and have had some limitations of activity on a weekly basis due to their neck pain. These subjects should not have had spinal manipulative treatment for at least two years and should not have had any adverse reactions to manipulative treatment or to benzodiazepines. They may not be regular users of benzodiazepine medications. They also should not be currently enrolled in an ongoing physical therapy program, though they may be taking analgesics, anti-inflammatories or other medications for their problem. They may continue with any ongoing exercise program. Subjects will also be excluded if they are pregnant, lactating or plan to be pregnant, if they have significant cardiac or pulmonary disease or if they plan on relocating during the course of the study. The subjects will also be evaluated by a trained and experienced manipulative practitioner (see below) for the presence of lesions which would be amenable to manipulation and by a medical physician for the absence of any contraindications to manipulative treatments.
