Non-specific Back Pain and Spinal Manipulation

Study Overview
=================
Brief Summary
-----------------
The main purpose of this study is to identify short-term predictors of positive responses to a spinal manipulation treatment. To do this, positive responses to treatment, characterized by improvement in pain score, functional capacity, as well as the global perceived change will be evaluated using single and multiple logistic regressions in which biomechanical variables, comfort, expectation will used as potential predictors.

Detailed Description
-----------------
The main purpose of this study is to identify short-term predictors of positive responses to a spinal manipulation treatment. To do this, positive responses to treatment, characterized by improvement in pain score, functional capacity, as well as the global perceived change will be evaluated at baseline and at 7 days. Pain score will be also assessed every day with text-tracking. Global perceived change will be evaluated using single and multiple logistic regressions in which biomechanical variables, comfort, expectation will used as potential predictors. 100 individuals with a history of non-specific back pain will be recruited in a chiropractic care center.

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Thoracic Back Pain (Numerical Analog Scale) | assessed by a 0-10 points scale, higher score means altered, lower score means improved | change from baseline to Day-7 | 
| Functional Disability (Quebec Back Pain Disability Scale) | assessed by 0-100 points questionary. Higher scores correlate to greater disability | change from baseline to Day-7 | 
| Global Perceived Change Scale | assessed by a 11-point score scale: higher score means improved, lower score means altered | at day-7 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Dosage | assessed by a force-sensing table recording data through a computer software | during the intervention | 
| Expectation (for improvement of pain and disability) | assessed by a 11-point score scale : higher score means improved, lower score means altered | at baseline (pre-intervention) | 
| Socio-demographic factors | assessed with a patient history questionary | at baseline(pre-intervention) | 
| Tampa Scale of Kinesiophobia | Questionary, Total score range from 17 to 68, Higher score indicate a worst outcome | at baseline(pre-intervention) | 
| Level of anxiety | Assessed using the State-Trait Anxiety Inventory (STAI) (score range from 20 (minimum) to 80 (maximum) : higher score mean a worst outcome) | at baseline (pre-intervention) | 
| Level of Comfort | Assessed with a 100mm scale : higher score means very comfortable | at baseline (post-intervention) |
