Descriptive Pilot Study of the Effects of a Standardized Neuromodulation Program on Cortical Brain Function in Chronic Low Back Pain Patients

Study Overview
=================
Brief Summary
-----------------
This study aims to evaluate neurofeedback-induced changes in brain function and the correlations between these changes and clinical scores by functional magnetic resonance imaging and electroencephalography in patients with low back pain.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Chronic low back pain<br> | Other: Neurofeedback treatment<br>* 20 sessions of neurofeedback of 5 minutes each consisting of : The patient is equipped with an electroencephalography headset. The feedback visual has the form of a candle flame and is modulated by alpha synchrony. The height of the flame is proportional to the intensity of the patient's pain. The patient has to concentrate on the height of this flame by thought to modulate it and, at the same time, to decrease the intensity of his own pain.<br>Other: functional magnetic resonance imaging (fMRI) scans<br>* The patient in alpha synchrony related state and in rating state will undergo an fMRI<br>|

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Description of the cortical zone activated by neurofeedback | Measure taken by electroencephalography | Day 20 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Back Beliefs Questionnaire (BBQ) | Auto-Questionnaire with 14 items describing the patient beliefs about chronic low back pain. The higher the score, the more the beliefs are negative | Day 20 | 
| Fear Avoidance Beliefs Questionnaire (FABQ) | Auto-Questionnaire with 16 items describing apprehension and avoidance in relation to professional activities and physical activities. | Day 20 | 
| Oswestry Disability Index (ODI) | Scale used to assess the functional disability of low back pain patients. | Day 20 | 
| Coping Strategies Questionnaire (CSQ) | Auto-Questionnaire with 21 items evaluating coping strategies specific to pain and especially in low back pain | Day 20 | 
| Hospital Anxiety and Depression Scale (HADS) | Auto-Questionnaire with 14 items used in the detection of anxio-depressive disorders. The higher the score, the more the depression is severe. | Day 20 | 
| Scale of lumbar pain in Quebec | Autoquestionnaire with 20 items used to measure the functional repercussions of low back pain on simple actions of everyday life. The higher the score, the more low back pains have a significant functional impact. | Day 20 | 
| Tampa scale | Autoquestionnaire with 17 items used to estimate the level of kinesiophobia (fear and fear) related to pain that leads to avoidance of activities considered to cause or increase pain or to cause or aggravate an injury. The higher the score, the higher the level of kinesiophobia. | Day 20 |
