Research Relevance

Neurophysiological mechanisms of the development, persistency and response to treatment in pain

The investigator Serge Marchand’s research program focuses on the characterization of different neurophysiological mechanisms involved in chronic pain (low back pain, fibromyalgia, neuropathic pain, irritable bowel syndrome, etc.). His team studies the interactions between different aspects of pain (pain intensity, unpleasantness) and scores of DNIC responses, concentrations of sex hormones (estrogen, progesterone, testosterone), age, autonomic responses, electrophysiological activity of the spine (nociceptive reflex [RIII]), and cortex (somatosensory evoked potentials [SEP]), brain imaging (fMRI and MR brain spectroscopy) and some phenotypes of neurotransmitters and their receptors.

Using these different approaches of investigation, the goal of Doctor Marchand’s research program is to characterize the specific factors involved in subpopulations of patients suffering of chronic pain and their response to different treatments. In addition, the correlation between these complex psychophysical, electrophysiological and biological measurements with questionnaires and clinical evaluations will open the way for the development of simple clinical assessment procedures to better guide the treatment of specific subgroups of patients. Ultimately, Doctor Marchand wants to be able to determine the subset of patients who will be more likely to respond to a specific treatment.
