Radicular patterns of pain drawings in LBP patients indicate severe pain conditions with the most neuropathic components, while axial LBP has the fewest. For the categorization of LBP, pain drawings help explain the underlying mechanism of pain, which might further improve mechanism-based treatment when used in clinical routines and research.
Burning and prickling were revealed as possible indicators for LBP chronicity. Combined with pain attacks and pressure pain, these 4 pain descriptors might be a promising adjunct to pain intensity in terms of outcome parameters for future LBP studies. The decrease of neuropathic pain syndromes in the elderly might be explained by degenerative processes. The presented work provides important insights on LBP management in the acute, subacute, and chronic stages.
Differences in somatosensory profiles in different localisations in 1 distinct disease (postherpetic neuralgia) were shown. This might have implications for future research and treatment regimes.
ObjectiveAxial spondyloarthritis (axSpA) is associated with decreased function and mobility of patients due to inflammation and radiographic damage. The Epionics SPINE device (ES), an electronic device that objectively measures spinal mobility, including range of motion (RoM) and speed (RoK) of movement, has been clinically validated in axSpA. We investigated the performance of the ES relative to radiographic damage in the axial skeleton of patients with axSpA.MethodsA total of 103 patients with axSpA (31 non- [nr-] and 72 radiographic [r]- axSpA) were consecutively examined. Conventional radiographs of the spine (including presence, number and location of syndesmophytes) and the sacroiliac joints (SIJs, rated by mNY criteria) were analyzed with the ES and assessments of function and mobility using analyses of covariance and Spearman correlation.ResultsThe number of syndesmophytes correlated positively with BASMI scores (r=0.38;P=0.016) and negatively with chest expansion (r=-0.39;P=0.015) and ES measurements (-0.53 ≤r≤ -0.34,P<0.03) except for RoM and RoK regarding rotation and RoK for extension of the lumbar and thoracic spine. In the radiographic evaluation of SIJs, the extent of damage correlated negatively with ES scores and metric measurements (-0.49 ≤r≤ -0.33;P<0.001). Patients with r-axSpA showed significantly worse ES scores for RoM, RoK and chest expansion than those with nr-axSpA.ConclusionThe ES scores, in accordance with mobility measurements, correlated well with the presence and extent of radiographic damage in the spine and SIJs. As expected, patients with r-axSpA had more severe impairments than those with nr-axSpA.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
