Effectiveness of Pain Neuroscience Education on Clinical and Psychosocial Variables in Chronic Low Back Pain

Effectiveness of Group Versus Individual Pain Neuroscience Education on Clinical and Psychosocial Outcomes in Patients With Chronic Low Back Pain: Protocol of a Randomized Controlled Trial

An educational intervention on the neurophysiology of chronic pain will be provided. The content of the intervention will be identical in the experimental groups (group and individual). The intervention has an active educational approach based on reconceptualizing the maladaptive beliefs that influence the fear-avoidance behavior of the participants through updated contents of the neuroscience of pain.

The effects of the intervention will be compared between the groups and the influence of the social determinants of health on the effects will also be determined.

The investigators hypothesize that there will be significant differences in favor of the group intervention group over the individual intervention groups. Furthermore, the effects will be influenced by the social determinants of health in both experimental groups.
