Introduction: The mirror neuron system in the brain is a functional area that is activated during both, the execution of a motor action and the visual recognition of the same motor action performed by others. As the pain matrix, which is a functional network of brain areas involved in pain processing, anatomically overlaps with this mirror neuron system, it was assumed that both systems could be functionally linked. The hypothesis was that chronic low back pain (CLBP) has an effect on the perception of visually presented actions, that would be specifically painful for the observer himself to perform. To see if the effect was specific for the painful region of the observer, CLBP patients were compared with patients suffering from chronic shoulder pain (CSP) and also with healthy controls, who were totally free of pain.
Materials and Methods: An experimental controlled study was performed including 16 CLBP patients (without shoulder pain), 9 CSP patients (without back pain) and 14 healthy controls. Videos of 2 movements were recorded with 2 healthy actors: a) a trunk rotation movement (TRM), typically painful for CLBP patients, with the actor lifting a box of 5, 10 or 15 kg on his left side, twisting his trunk in an upright position and placing it down on his right side again; b) a manual transfer movement (MTM), typically painful for CSP patients, with the actor sitting on a bench with his spine supported, grabbing a dumbbell of 0, 3.5 or 7 kg on his right side, moving it over his head, passing it to his left hand and putting...
