Effectiveness of a Pain Neuroscience Education Programme on Physical Activity in Patients With Chronic Low Back Pain

Effectiveness of a Pain Neuroscience Education Programme on Physical Activity in Patients With Chronic Low Back Pain. Randomised Controlled Trial

Proposing ways to effectively counter chronic low back pain through non-drug intervention is a major public health issue due to the prevalence and health costs of this condition. The back school (BS) is based on spinal economics and a biomechanical model. A convergence of evidence indicates that this type of program does not bring any mid- or long-term benefit. Faced with this observation, a Pain Neuroscience Education (PNE) has been developed based on a biopsychosocial model. Chronic low back pain is the consequence of a complex dynamic of multifactorial origin where the body lesion is no longer the only cause of the pain. Studies have shown that PNE has a positive effect on pain perception. One of the limitations of these studies is that they do not allow objective measurement of physical activity performed at a distance from a therapeutic program for patients who have benefited from these educational programs. Yet, physical activity is an essential variable in health and more specifically in the fight against pain in patients with chronic low back pain. The investigators believe that physical activity is a key factor in improving the condition of patients with chronic low back pain. Consequently, physical activity is an indicator of success but also a guarantee for a lasting effect of educational treatment. In order to measure this physical activity, the use of activity monitor (connected watch) developed in recent years now makes it possible to collect data in an ecological manner that is more objective than the data collected via self-questionnaires. The main objective of the study is to measure the effectiveness of a PNE on physical activity three months after the intervention compared to BS in patients with chronic low back pain receiving a multidisciplinary rehabilitation program. The secondary aims are to compare effectiveness of PNE versus BS on pain, quality of life, kinesiophobia, pain catastrophizing, central sensitization at 3 months and at one year after the intervention. In addition, an exploratory analysis will be conducted to determine predictors of physical activity maintenance. The investigators expect to observe greater physical activity in patients who have received a PNE program compared to the physical activity of patients who have completed an BS program.

The Pain Neuroscience Education program takes place over ten days consisting of providing knowledge about the neurophysiology and central processes of pain (nociceptive pathways, inhibitory circuits, peripheral and central sensitization, nervous system plasticity) as well as psychosocial factors and beliefs contributing to chronic pain. Workshops will use experimental data from neuroscience, but also analogies, brainstorming or games. Questions are proposed to the patient at the end of each theme.

The Back School program takes place over ten days. It begins with a presentation of spinal economy, which consists of promoting the protection of the back. Then, the anatomy and biomechanics of the spine as well as the most common spinal pathologies are presented. On this biomechanical basis, the other sessions consist in indicating the gestures and postures to adopt, always according to the protection policy, in different situations. These different sessions alternate between theory and practical exercises.
