cervical and upper thoracic mobilization and manipulation for mechanical neck pain

Conditions: Neck Pain

Summary: the objective of this pilot study is to determine the feasibility of a large-scale trial. the primary objective is to determine if manipulation applied to the cervical and thoracic spines is more effective than mobilization applied to the cervical and thoracic spines for the management of patients with mechanical neck pain.

all potential subjects will be assessed for eligibility prior to signing the informed consent by filling out a demographic questionnaire and through a subjective interview that will include a health history examination performed by a physical therapist that has received additional training in orthopedic manual therapy. a physical therapist (pt) is a highly educated licensed health care professional that has graduated from an accredited university and has passed a national licensure exam. physical therapists specialize in movement disorders and are well trained in the examination and treatment for primary and secondary medical conditions pertaining to the cardiovascular, neuromuscular, musculoskeletal, and integumentary body systems. manual therapy interventions for the neck and thoracic spine including manipulations are taught in entry-level physical therapy programs. continuing education courses are available for physical therapists to get advanced training in manual therapy. this training involves not only improving the skill set of the therapist but also focuses on enhancing the knowledge of the therapist concerning the safety of patients. each of the treating therapists will have certifications in manual therapy. screening for inclusion and exclusion criteria will be done by the treating pt by means of assessing subjective outcomes, patient demographic, and through their subjective history examine. subjects will then be given the informed consent to be read and signed if they agree to participate. subjects will be permitted to ask any questions relative to any study procedures they do not understand. two physical therapists at each facility will be used in order to keep the outcome measures blinded. the treating therapist or clinic pt will perform the examination/evaluation and perform all manual therapy treatments during the first 2 visits of care. pending there are no scheduling conflicts; the treating therapist will continue to provide the treatment. if there is a scheduling conflict, another physical therapist will provide the patient's care until the next available opening on the treating therapist. the recording therapist, or research therapist, will record all the dependent variables and will remain blinded to group allocation. this is the only assignment given to the research therapist. the treating therapist will be blinded to all results of the outcome data except in the case where data is needed for clinical decision making in order to optimize patient outcomes. after informed consent is attained, outcome data will then be collected by the recording physical therapist that is not aware of group allocation. the data collected will include the neck disability index (ndi), patient specific functional score (psfs), numeric pain rating scale (nprs), deep cervical flexion test (dcf), cervical range of motion (crom) using a crom, therapist equipoise, and patient preference. following initial data collection, each subject will be randomized via concealed allocation to receive either mobilization or manipulation directed to the cervical and upper thoracic spine for the first two treatment visits. the patient will be treated on day 1 with their randomized treatment technique. the manual technique chosen for treatment by each clinician will be determined by the results of their physical examination. other interventions included for both groups will include a standardized exercise program and advice, encouragement, and assurance. immediately following the treatment procedures, data will be collected again and will include the nprs, global rating of changes (groc), cervical range of motion, and dcf. the therapist will determine the next appropriate follow-up visit. data will again be collected at the beginning of the 2nd visit follow-up and will include nprs, groc, cervical range of motion, dcf, psfs, and ndi by the blinded physical therapist. treatments of cervical and thoracic mobilization or manipulation will occur again based on group allocation established prior. the technique used by the treating clinician will be based on their assessment of the patient and again will follow group allocation. after the 2nd visit (day 3), the treating physical therapist is able to add or remove treatments, as they deem necessary to improve the patient's condition. orthopedic manual therapy (mobilization or manipulation) may be adjusted based on patient need as well. subsequent visits and plan of care will continue under the direction of the physical therapist based on the patient's need. final data collection performed at discharge will include the ndi, psfs, groc, and total number of visits, patient satisfaction, therapist equipoise, and total days of care. analysis: baseline characteristics of all subjects will be compared using either a t-test or chi square as appropriate. a two way multivariate analysis of variance (manova) will be used to compare outcomes of ndi, psfs, and nprs at baseline, at day 3, and at day 30.

Eligibility criteria:
inclusion criteria: * subjects aged 18-70 years old with a chief complaint of reproducible neck pain and an ndi score of 10 or greater. exclusion criteria: * subjects are excluded if they have had recent whiplash or significant trauma, demonstrate red flag items such as malignancy, radiculopathy, myelopathy, fracture, metabolic disease, rheumatoid arthritis, long-term steroid use, or history of neck surgery. additional exclusion criteria including neck pain of \<2 on the nprs, psfs ≤ 8, no prior treatment within 6 weeks time, upper limb symptoms, or any pending litigation. finally, if a therapist determines the patient has a neck condition that is highly irritable where the manipulation is not appropriate, they will be excluded.
