Purpose: The purpose of this follow-up study in which patients will be randomly assigned to receive thoracic spine thrust manipulation followed by therapeutic exercises or therapeutic exercise alone will be to investigate the validity of the previously developed CPR. If the CPR is indeed meaningful, patients who are positive on the CPR and receive thoracic spine thrust manipulation should experience improved outcomes compared to patients who are negative on the CPR and receive thoracic spine manipulation, and compared to patients who are positive on the CPR but receive the intervention believed to be effective for another subgroup of patients with neck pain.
