Background: Controversy exists with the presence of alterations in descending pain inhibition mechanisms in patients with non‐specific neck pain (NSNP). The aim of the present study was to evaluate the status of conditioned pain modulation CPM, remote pressure pain thresholds (PPT), and psychological factors in a specific subgroup of patients with NSNP such as young adult students. In addition, possible associations between CPM, psychological factors, and pain characteristics were analyzed. Methods: Thirty students with recurrent or chronic NSNP and 30 pain‐free students were included in this cross‐sectional study. The following measures were assessed: CPM, remote PPT, psychological factors (depression, anxiety, pain catastrophizing, and kinesiophobia), pain characteristics (duration, intensity, severity of chronic pain, interference with daily life), and central sensitization inventory (CSI). Results: No significant differences were found in the efficacy of CPM between students with chronic or recurrent NSNP and pain‐free students (β coefficient = −0.67; 95% CI = −1.54, 0.20). However, students with pain showed a significantly higher remote PPT (mean difference = −1.94; 95% CI = −2.71, −1.18). and a greater presence of anxious (mean difference = 6; 95% CI = 2, 9) and depressive symptoms (mean difference = 8.57; 95% CI = 3.97, 13.16). In addition, significant moderate or strong correlations were found between CPM and pain intensity (partial r = 0.41), pain catastrophizing and mean pain intensity (r = 0.37), grade (r = 0.50), and interference of pain (r = 0.57), kinesiophobia and disability (r = 0.38), and depression and CSI (r = 0.39). Conclusions: Young adult students with chronic or recurrent NSNP present remote hyperalgesia and symptoms of depression and anxiety but not dysfunctional CPM. [ABSTRACT FROM AUTHOR] |
