The introduction of modern sub-perception modalities has improved the efficacy of spinal cord stimulation (SCS) in refractory pain syndromes of the trunk and lower limbs. The objective of this study was to evaluate the effectiveness of low and high frequency SCS among patients with chronic pain.
Learn More >Posttraumatic headache is difficult to define and there is debate about the specificity of the 7-day headache onset criterion in the current definition. There is limited evidence available to guide decision making about this criterion.
Learn More >The importance of neck pain and the trigeminocervical complex in migraine is of high pathophysiological interest since a block to the greater occipital nerve is more effective for some primary headaches than others. This observational study hypothesised that the response to manual palpation of the upper cervical spine predicts the efficacy of the greater occipital nerve-block.

Learn More >This study aimed to test empirically the developmental goal pursuit model of paediatric chronic pain, which draws upon Self-Determination Theory for understanding risks and resources for living with chronic pain. This study examined the relationship between basic psychological need satisfaction (i.e. the satisfaction of the needs for autonomy, relatedness and competence) and the fear-avoidance model of pain in adolescents suffering from chronic pain. Hundred and twenty adolescents (mean age = 14.52, 71.6% female), receiving treatment through paediatric pain centres for chronic pain, were enrolled. Adolescents completed measures of basic psychological need satisfaction, fear and avoidance of pain, and pain-related functional impairment. Path analyses model indicated that higher levels of autonomy and competence satisfaction were associated with lower levels of functional disability, through the mediation of fear and avoidance of pain. Relatedness satisfaction was not significatively related to fear of pain, avoidance, and functional disability. The integration of Self-Determination Theory in the paediatric pain literature may further our understanding of potential resources for decreasing functional disability in children living with chronic pain.
Learn More >Recent studies have highlighted multicolumn spinal cord stimulation (SCS) efficacy, hypothesizing that optimized spatial neural targeting provided by new-generation SCS lead design or its multicolumn programming abilities could represent an opportunity to better address chronic back pain (BP).
Learn More >Research suggests that the way others react to a pain flare-up impacts on psychological and pain-related symptoms in chronic pain (CP). Experiencing validation from others is associated with less negative emotions and better functioning. Contrarily, experiencing criticism is linked to greater pain intensity and worse functioning. Nonetheless, studies are limited by an exclusive focus on spouses rather than significant other relationships, the use of proxy constructs (e.g., social support, responsiveness, solicitousness) rather than specific measures of validation and criticism, and a focus on significant others' behavior rather than patients' subjective experience. This study examines the psychometric properties of a new measure – Perceived Validation and Criticism in Pain Questionnaire (PVCPQ), and tests its contribution to functional impairment beyond pain intensity, sociodemographic and medical-related variables, positive and negative affect, safeness, and compassion from others.
Learn More >Objectives A significant proportion of adolescents with chronic musculoskeletal pain (CMP) experience difficulties in physical functioning, mood and social functioning, contributing to diminished quality of life. Generalized joint hypermobility (GJH) is a risk factor for developing CMP with a striking 35-48% of patients with CMP reporting GJH. In case GJH occurs with one or more musculoskeletal manifestations such as chronic pain, trauma, disturbed proprioception and joint instability, it is referred to as generalized hypermobility spectrum disorder (G-HSD). Similar characteristics have been reported in children and adolescents with the hypermobile Ehlers-Danlos Syndrome (hEDS). In the management of CMP, a biopsychosocial approach is recommended as several studies have confirmed the impact of psychosocial factors in the development and maintenance of CMP. The fear-avoidance model (FAM) is a cognitive-behavioural framework that describes the role of pain-related fear as a determinant of CMP-related disability. Content Pubmed was used to identify existing relevant literature focussing on chronic musculoskeletal pain, generalized joint hypermobility, pain-related fear and disability. Relevant articles were cross-referenced to identify articles possibly missed during the primary screening. In this paper the current state of scientific evidence is presented for each individual component of the FAM in hypermobile adolescents with and without CMP. Based on this overview, the FAM is proposed explaining a possible underlying mechanism in the relations between GJH, pain-related fear and disability. Summary and outlook It is assumed that GJH seems to make you more vulnerable for injury and experiencing more frequent musculoskeletal pain. But in addition, a vulnerability for heightened pain-related fear is proposed as an underlying mechanism explaining the relationship between GJH and disability. Further scientific confirmation of this applied FAM is warranted to further unravel the underlying mechanism. In explaining disability in individuals with G-HSD/hEDS, it is important to focus on both the physical components related to joint hypermobility, in tandem with the psychological components such as pain-related fear, catastrophizing thoughts and generalized anxiety.
