Additional Effect of Pain Neuroscience Education to Spinal Manipulative Therapy in Chronic Low Back Pain

1\) The application of a global low-amplitude and high-speed manipulation at the upper thoracic region between T1 and T5 levels in the dorsal decubitus position and 2) Techniques of post-anterior central mobilization applied for 30 seconds with an average of 30 repetitions in each lumbar vertebra, from L5 to L1, using grade II joint mobilization (patients positioned in the ventral decubitus position).

All participants in the PNE + SMT group will initially receive a workshop on PNE in which different concepts of pain neuroscience and pain reconceptualization will be discussed and a power-point presentation with metaphors and animated videos on the topic will be employed. The PNE program will be held in 2 sessions of 40 minutes each. The topics of the intervention program will be divided into four thematic topics according to Explain Pain concepts.
