The Nociception Coma Scale is a nociception behaviour observation tool, developed specifically for patients with disorders of consciousness (DOC) due to (acquired) brain injury. Over the years, the clinimetric properties of the NCS and its revised version (NCS-R) have been assessed, but no formal summary of these properties has been made. Therefore, we performed a systematic review on the clinimetric properties (i.e. reliability, validity, responsiveness and interpretability) of the NCS(-R). ⋯ Important aspects of reliability, construct validity and responsiveness have been studied in depth and with sufficient methodological quality. The overview of clinimetric properties in this study shows that the NCS and NCS-R are both valid and useful instruments to assess nociceptive behaviour in DOC patients. The studies provide guidance for the choice in NCS-R cut-off value for possible pain treatment and cautions awareness of interprofessional differences in NCS-R measurements.

The timing of diagnosis of complex regional pain syndrome (CRPS) 1 remains a challenge due to the large heterogeneity of clinical presentations. We describe the distribution and differences in outcomes and clinical manifestations between time points and patient groups with and without CRPS 1 following an initiating event. ⋯ This prospective cohort study follows patients with complaints most suspected for complex regional pain syndrome (CRPS) 1. CRPS 1 develops within 8 weeks following a noxious event. Although many CRPS 1 patients reach partial remission within the 3 months, symptoms do not improve significantly at 1 year.

Youth with chronic pain are at higher risk for obesity than the general population. In youth with chronic pain, obesity exacerbates pain-specific activity limitations, and in adults with chronic pain, obesity perpetuates a cycle of disability. The current study examined whether weight status predicts functional disability outcomes over time in youth with chronic pain. ⋯ This study shows that obesity impedes improvement in functioning for youth with chronic pain. On the basis of these findings, interventions should be tailored to the unique challenges of this population.

Many behavioural scales are available to assess pain but none are suitable for a quick evaluation of non-sedated and non-geriatric adults. The Behavioural Observation Scale 3 (BOS-3) is short, composed of five items. This study examined its feasibility and diagnostic performances. ⋯ This study describes the diagnostic performances of a behavioral pain assessment scale designed for non-geriatric and non-sedated adults. The results show its validity in non-communicating patients and suggest its usefulness as an ancillary tool in communicating patients in whom simple numerical scales are often insufficient.

Inflammatory bowel diseases (IBD) are systemic, chronic inflammatory conditions that predominately affect the gastrointestinal tract and can induce abdominal pain. Besides, many IBD patients complain about headaches in daily practice. The objective was to assess the prevalence of headaches, including migraines and pain with neuropathic characteristics (NC), in IBD patients compared to historical controls from the general population. ⋯ Migraine prevalence was two-fold higher in IBD patients compared to the general population, was generally poorly treated and a systematic screening for migraine should be done by IBD physicians in daily practice to provide adequate therapeutics.
