Objectives: The aim of this study was to determine whether visualization of the back influenced parameters of movement-related pain in people with chronic nonspecific low back pain. Methods: We used a randomized cross-over experiment in which 25 participants performed repeated lumbar spine movements under 2 conditions. In the visual feedback condition, patients were able to visualize their back as it moved by the use of mirrors. In the control condition, the mirror was covered so no visualization of the back was possible. Results: The average postmovement pain intensity after participants had moved with visual feedback was less (35.5+/-22.8 mm) than …

Evidence indicates that chronic non-specific low back pain (CNSLBP) is associated with alteration in the brain’s cortical representation of the back, resulting in body perception disturbance and contributing to the condition [1,2]. This study investigated perception via ‘cortical’ sensory tests, in this case two-point discrimination and graphaesthesia—whose results partly depend on the integrity of cortical representation [2]. The hypothesis was dysfunction in these higher-order tasks, with simple tactile thresholds remaining unchanged. Furthermore a relationship between cortical sensation and severity of the condition was predicted.

A mismatch between the brain's motor control and sensory systems has been suggested as one mechanism whereby maladaptive neuroplastic changes contribute to the experience of chronic pain. Several studies have investigated this hypothesis by artificially inducing a state of sensory-motor incongruence using mirrors. The data to date appear to suggest that creating an environment of sensori-motor incongruence induces various sensory changes and feeling of peculiarity, however the effect on pain is less clear. The aim of this study was to test the hypothesis that healthy participants would demonstrate reduced pain thresholds and report greater intensity of pain in a condition …
