Exercise Therapy for Recurrent Low Back Pain: Unraveling the Puzzle of Peripheral Muscle and Central Brain Changes (B670201420984)

Plain-language summary

Exercise therapy has been shown to be effective in decreasing pain and improving function for patients with recurrent low back pain (LBP). Research on the mechanisms that trigger and/or underlie the effects of exercise therapy on LBP problems is of critical importance for the prevention of recurring or persistence of this costly and common condition. One factor that seems to be crucial within this context is the dysfunction of the back muscles. Recent pioneering results have shown that individuals with recurring episodes of LBP have specific dysfunctions of these muscles (peripheral changes) and also dysfunctions at the cortical level (central changes). This work provides the foundation to take a fresh look at the interplay between peripheral and central aspects, and its potential involvement in exercise therapy. The current project will draw on this opportunity to address the following research questions: What are the immediate (after a single session) and the long-term effects (after 18 repeated sessions) of exercise training on: (1) back muscle structure; (2) back muscle function; (3) the structure of the brain; (4) and functional connectivity of the brain. This research project also aims to examine whether the effects are dependent on how the training was performed. Therefore a specific versus a general exercise program will be compared.
