Othman R, et al. - In view of the correlation of somatosensory abnormalities with clinical pain outcomes in individuals with spinal pain, researchers conducted this systematic review examining the level of evidence of correlations between psychological, social, physical activity, and sleep measures and somatosensory function (assessed via sensory psychophysical testing) among these individuals. For this work, they performed a literature search in 6 electronic databases from their inception to June 2018. The included studies led to the recognition of 17 factors; of these, pain catastrophizing, depression, and pain-related fear have significant negative (small to fair) correlations with pain thresholds. For all the investigated factors, they identified a “very low” to “moderate” quality of evidence. Subgroup analysis suggests that in individuals with low back pain, pain catastrophizing/fear of movement and pain thresholds have a smaller effect size. Findings suggest a negative association of psychological factors with pain thresholds and that adjustment of these factors is required when establishing predictive correlations between somatosensory function and pain outcomes in individuals with spinal pain.
