Central Neuromodulation of Pain Through Music in Healthy Subjects

Study Overview
=================
Brief Summary
-----------------
The present research aims to study the neuromodulatory effect of music on the sensory component of pain. The activation of pain control systems, through music, would pave the way for rehabilitation prospects for patients with a deficit of these controls.

Detailed Description
-----------------
Pain is a multidimensional, complex and universal phenomenon that would be faced by almost one in two European adults. To meet the needs in terms of public health, contemporary medicine is gradually reintegrating the use of complementary therapeutic methods. Music therapy is a non-medical intervention that is particularly suited to pain problems. The therapeutic use of music is an economical, practical and safe method. Many clinical studies show that this activity promotes a significant decrease in pain. The ability of passive listening to music to reduce the perception of pain has been called music-induced analgesia. The neuro-psycho-physiological mechanisms that underlie this phenomenon remain poorly understood. One hypothesis, still discussed, proposes that listening to music would stimulate, directly or indirectly, endogenous mechanisms of modulation of pain, stemming from the brainstem. In individuals undergoing nociceptive tonic stimulation, the specific neuronal activation induced by listening to music demonstrates the involvement of inhibitory descending pathways. A measurement of pain control mechanisms would account for the impact of music on central awareness. The purpose of this research is therefore to study the neuromodulatory effect of music on the sensory component of pain. The activation of pain control systems, through music, would pave the way for rehabilitation prospects for patients with a deficit of these controls.

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Evaluation of Visual Analogue scale (VAS) | Visual Analogue Scale (VAS) measured at 2 minutes of stimulation during the temporal summation phase, starting from a basic VAS calibrated at 50/100. Pain is assessed continuously throughout this test using a computerized analog visual scale. | 20 minutes | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Average VAS of the subject over the period P1 | The period P1 represents the first stimulation or the first time summation test. It is a tonic pain test by applying the thermode. The average VAS will be measured during this period. Pain is assessed continuously throughout this test using a computerized analog visual scale. | 2 minutes | 
| Average VAS of the subject over the period P2 | The period P2 represents the second stimulation or activation of the DNIC (Diffuse Nociceptive Inhibitive Control). This is the induction of cold thermal nociceptive stimulation (CPT : cold pressor test). The average VAS will be measured during this period. Pain is assessed continuously throughout this test using a computerized analog visual scale. | 2 minutes | 
| Average VAS of the subject over the period P3 | The period P3 represents the third stimulation or the second time summation test. This is the second tonic pain test by applying the thermode.The average VAS will be measured during this period. Pain is assessed continuously throughout this test using a computerized analog visual scale. | 2 minutes | 
| Evaluation of numerical scale | Numerical scale (overall numerical scale over the period) will be measured for each stimulation period (P1, P2, P3). This scale assesses pain and is graded from 0 (no pain) to 100 (maximum pain imaginable). | 20 minutes | 
| Difference in average VAS P1-P3 | The difference in average VAS between period P1 and period P3 will be calculated. Pain is assessed continuously throughout this test using a computerized analog visual scale. | 20 minutes | 
| Difference in Pressure Pain Threshold (PPT) before and after the procedure | The difference in Pressure Pain Threshold (PPT) will be measured before and after the procedure. | 1 hour and 30 minutes |
