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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Neck Disability Index (NDI) | Questionnaire used to measure how neck pain affects activities of daily living. Each of the 10 items are scored from 0-5, the maximum score is 50. Higher scores signify greater disability. A score over 34 signifies complete disability. | 90 days | 
| SF-36 Quality of Life Survey | Questionnaire used to measure quality of life. All questions are scored on a scale from 0 to 100, with 100 representing the highest level of functioning possible. The total score is calculated as a percentage of the total points possible. A higher total percent signifies better outcomes. | 90 days | 
| Visual Analog Scale (VAS) | Scale used to measure pain. The subject will mark their pain on a scale with a length of 100mm. The scale is scored by measuring (mm) from the left end of the scale to the subject's marking. The VAS is scored from 0-100, higher scores signify a greater amount of pain. | 90 days |
