Comparison of Two Thoracic Manipulation Techniques to Improve Neck Pain in Dentistry Students

Study Overview
=================
Brief Summary
-----------------
This study is designed to compare the short term effects of two different thoracic spine thrust manipulation techniques on neck range of motion, pain, and self-reported disability in a sample of dental students experiencing neck pain. The hypothesis of the study is that there will be a difference between the two thoracic spine thrust manipulation techniques for short term effects on neck range of motion, pain, and self-reported disability in a sample of dental students experiencing neck pain.

Eligibility Criteria
-----------------
Inclusion Criteria: Current student at the Arizona School of Dentistry and Oral Health (ASDOH) at A. T. Still University Primary complaint of neck pain with or without symptoms that spread down into one arm Overall rating of neck pain intensity is at least 3/10; the overall rating is the overall average of the participant's rating of current, least, and worst pain experienced over the previous 24 hours on separate numeric pain rating scales where 0 corresponds to no pain and 10 corresponds to worst pain possible. Neck Disability Index (NDI) score > 10 points (measure of self-reported disability with a 0 to 50 point scale where higher scores indicate higher levels of disability. Proficient in speaking and reading English to complete outcome questionnaires Exclusion Criteria: Neck pain related to a motor vehicle accident or other trauma within the previous 6 weeks Neck pain that spreads down into both arms Low back pain or thoracic origin of pain Nerve root involvement; defined as the presence of two or more neurological findings (e.g. decreased strength, diminished deep tendon reflex, or decreased sensation) at the same nerve root level Diagnosis of cervical spine stenosis (narrowing of the central canal that contains the spinal cord) History of spinal tumors, spinal infection, cervical spine fracture, or previous neck surgery Pending legal action related to current episode of neck pain Contraindications to thoracic spine thrust manipulation serious pathologies or conditions (tumor, fracture, metabolic diseases, rheumatoid arthritis, osteoporosis, history of prolonged steroid use) hyperreflexia unsteadiness during gait Nystagmus Loss of visual acuity Impaired sensation of the face Altered taste The presence of pathological reflexes pregnancy or considering pregnancy

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Thoracic Spine Thrust in Seated Position<br>Thoracic spine thrust manipulation will be applied two times at each of two treatment sessions while the participant is in a seated position. | Other: Thoracic Spine Thrust in Seated Position<br>* The thoracic spine manipulation used here is a manipulation technique that involves positioning the patient so that a small amplitude quick stretch can be applied to the least mobile area of the thoracic spine as identified by the licensed physical therapist during spinal segmental mobility testing.<br>|
| Experimental: Thoracic Spine Thrust in Supine Position<br>Thoracic spine thrust manipulation will be applied two times at each of two treatment sessions while the participant is in the supine position. | Other: Thoracic Spine Thrust in Supine Position<br>* The thoracic spine manipulation used here is a manipulation technique that involves positioning the patient so that a small amplitude quick stretch can be applied to the least mobile area of the thoracic spine as identified by the licensed physical therapist during spinal segmental mobility testing.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in Neck Pain Intensity | Each participant's neck pain intensity will be assessed by use of the Numeric Pain Rating Scale (NPRS of 0-10) | Collected at baseline assessment during initial visit before 1st treatment, one week later before 2nd treatment, and one week later at follow-up appointment - total of 2- 3 weeks anticipated | 
| Change in Neck Range of Motion (ROM) | Neck range of motion will be measured by a licensed Physical Therapist | Collected at baseline assessment during initial visit before 1st treatment, one week later before 2nd treatment, and one week later at follow-up appointment - total of 2- 3 weeks anticipated | 
| Change in Neck Disability Index (NDI) | The Neck Disability Index (NDI) is a self-reported measure of disability consisting of a 0-50 point scale where higher scores indicate higher levels of disability | Collected at baseline assessment during initial visit before 1st treatment, one week later before 2nd treatment, and one week later at follow-up appointment - total of 2- 3 weeks anticipated | 
| Change in Shortened version of the Disabilities of the Arm, Shoulder, and Hand (QuickDASH) questionnaire (QuickDASH) | The shortened version of the Disabilities of the Arm, Shoulder, and Hand (Quick DASH) questionnaire is a self-report measure of function that can assess how neck pain may be impacting daily activities that require use of the upper limb | Collected at baseline assessment during initial visit before 1st treatment, one week later before 2nd treatment, and one week later at follow-up appointment - total of 2- 3 weeks anticipated |
