Understanding brain factors in chronic low back pain

Assessing the Predictability of Brain, Psychological and Epigenetic Determinants for Optimizing the Treatment of Chronic Low Back Pain

Université de Sherbrooke · NCT05963451

This study looks at how the brain might be involved in chronic low back pain to help improve diagnosis and treatment for people who have been dealing with this pain for six months or longer.

What this trial studies

This observational study aims to explore the role of the brain in patients suffering from chronic low back pain (CLBP). By investigating the structural and functional properties of the brain, the study seeks to enhance the understanding of the mechanisms contributing to CLBP. The findings could lead to improved diagnosis and treatment strategies for this prevalent condition, which affects millions globally. The study will involve patients with a history of low back pain lasting six months or more, focusing on their brain characteristics without any direct interventions.

Who should consider this trial

Good fit: Ideal candidates for this study are individuals experiencing chronic low back pain for at least six months, with specific pain characteristics and no recent surgical interventions.

Not a fit: Patients with neurological, cardiovascular, or pulmonary disorders, or those who have undergone recent surgical interventions for back pain may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more effective diagnosis and treatment options for patients suffering from chronic low back pain.

How similar studies have performed: While the role of the brain in chronic pain is an emerging field, this specific approach to understanding CLBP through brain characteristics is relatively novel and has not been extensively tested.
