Background: Central sensitization (CS) has an important role in chronic musculoskeletal (MSK) pain, which is one of the leading causes of disability worldwide.
Objectives: To investigate the relationship between CS-related symptoms and disability in chronic MSK pain.
Design: Multi-center cross-sectional survey.
Methods: Demographic and clinical variables including location, duration, and severity of pain were recorded. In the examination of disability, Istanbul Low Back Pain Disability Index for low back pain, Neck Pain and Disability Scale for neck pain, Quick Disability of the Arm, Shoulder, and Hand for shoulder/upper extremity pain, and Knee Injury and Osteoarthritis Outcome Score for knee pain were used. CS-related symptoms were investigated via the central sensitization inventory (CSI). Based on CSI scores, patient data were compared using the T test and an ANOVA. The association between CSI and selected variables was investigated using Pearson correlation and multivariate regression analysis.
Results: The mean CSI score of five hundred participants was 40.46 (SD: 15.87). Patients with CSI≥40 were found to have higher levels of pain and disability and a poorer quality of life (p < 0.05). In ANOVA, significant differences between groups were observed in CS severity levels for VAS, symptom duration, and all clinical scores (p < 0.01). In the multivariate regression analysis, CSI and VAS scores were found to be related to disability in all pain groups, while pain duration was effective only in the change of knee disability.
Conclusion: CS-related symptoms, which are related to increased pain and disability, should be closely monitored in patients with chronic MSK pain.

Background: Human placental hydrolysate (hPH) contains anti-inflammatory substances. This study aimed to analyze whether injecting hPH into the subacromial space could reduce pain in patients with shoulder impingement syndrome.
Methods: This single-blind, randomized controlled study enrolled 50 patients with shoulder impingement syndrome who were randomly assigned to either the hPH or placebo groups.
Development of a standardized patient-reported clinical questionnaire for children with spinal pain.

Background: Spinal pain affects up to 30% of school-age children and can interfere with various aspects of daily life, such as school attendance, physical function, and social life. Current assessment tools often rely on parental reporting which limits our understanding of how each child is affected by their pain. This study aimed to address this gap by developing MySpineData-Kids ("MiRD-Kids"), a tailored patient-reported questionnaire focusing on children with spinal pain in secondary care (Danish hospital setting).

This study explores FD/MAS patient's perceptions about their disease and its impact on their quality of life. We have evaluated quality of life (QoL) in French Fibrous Dysplasia/MacCune-Albright Syndrome (FD/MAS) patients using a qualitative approach with focus groups to explore perceptions, symptoms and limitations associated with FD/MAS and a quantitative method with the Short Form-36 (SF36) to quantify QoL. Focus groups revealed the heterogeneity of FD forms and allowed for understanding the reasons of reduced QoL.

Objective: Patients with therapy-refractory chronic spinal pain after spinal surgery experience increased disability, resulting in substantial loss of employment and consequently lower quality of life. Despite findings that rehabilitation improves socio-economic outcomes in other chronic pain conditions, evidence for patients with chronic spinal pain after spinal surgery is limited. A systematic review was conducted to provide an overview of rehabilitation interventions and their effectiveness to improve work participation for patients with chronic spinal pain after spinal surgery.
