Background: Compelling evidence has demonstrated that impaired central pain modulation contributes to persistent pain in patients with chronic whiplash associated disorders (WAD) and fibromyalgia (FM). However, there is limited research concerning the influence of stress and relaxation on central pain modulation in patients with chronic WAD and FM., Objectives: The present study aims to investigate the effects of acute cognitive stress and relaxation on central pain modulation in chronic WAD and FM patients compared to healthy individuals., Study Design: A randomized crossover design was employed., Setting: The present study took place at the University of Brussels, the University Hospital Brussels, and the University of Antwerp., Methods: Fifty-nine participants (16 chronic WAD patients, 21 FM, 22 pain-free controls) were enrolled and subjected to various pain measurements. Temporal summation (TS) of pain and conditioned pain modulation (CPM) were evaluated. Subsequently, participants were randomly allocated to either a group that received progressive relaxation therapy or a group that performed a battery of cognitive tests (= cognitive stressor). Afterwards, all pain measurements were repeated. One week later participant groups were switched., Results: A significant difference was found between the groups in the change in TS in response to relaxation (P = 0.008) and cognitive stress (P = 0.003). TS decreased in response to relaxation and cognitive stress in chronic WAD patients and controls. In contrast, TS increased after both interventions in FM patients. CPM efficacy decreased in all 3 groups in response to relaxation (P = 0.002) and cognitive stress (P = 0.001)., Limitations: The obtained results only apply for a single session of muscle relaxation therapy and cognitive stress, whereby no conclusions can be made for effects on pain perception and modulation of chronic cognitive stress and long-term relaxation therapies., Conclusions: A single relaxation session as well as cognitive stress may have negative acute effects on pain modulation in patients with FM, while cognitive stress and relaxation did not worsen bottom-up sensitization in chronic WAD patients and healthy persons. However, endogenous pain inhibition, assessed using a CPM paradigm, worsened in chronic WAD and FM patients, as well as in healthy people following both interventions.

Introduction: Central sensitization accounts for chronic 'unexplained' pain in a wide variety of disorders, including chronic whiplash-associated disorders, temporomandibular disorders, chronic low back pain, osteoarthritis, fibromyalgia, chronic fatigue syndrome and chronic tension-type headache among others. Given the increasing evidence supporting the clinical significance of central sensitization in those with unexplained chronic pain, the awareness is growing that central sensitization should be a treatment target in these patients., Areas Covered: This article provides an overview of the treatment options available for desensitizing the CNS in patients with chronic pain due to central sensitization. It focuses on those strategies that specifically target pathophysiological mechanisms known to be involved in central sensitization. In addition, pharmacological options, rehabilitation and neurotechnology options are discussed., Expert Opinion: Acetaminophen, serotonin-reuptake inhibitor drugs, selective and balanced serototin and norepinephrine-reuptake inhibitor drugs, the serotonin precursor tryptophan, opioids, N-methyl-d-aspartate (NMDA)-receptor antagonists, calcium-channel alpha(2)delta (a2δ) ligands, transcranial magnetic stimulation, transcutaneous electric nerve stimulation (TENS), manual therapy and stress management each target central pain processing mechanisms in animals that - theoretically - desensitize the CNS in humans. To provide a comprehensive treatment for 'unexplained' chronic pain disorders characterized by central sensitization, it is advocated to combine the best evidence available with treatment modalities known to target central sensitization., (© 2011 Informa UK, Ltd)

The purpose of this paper was first to gain an in-depth understanding of the barriers and facilitators to implementing the BPS model and pain neuroscience education in the current Lebanese physical therapy health care approach and explore its acceptability. A qualitative semi-structured interview using purposive sampling was conducted with eight Lebanese physical therapists practising in different governorates. The transcribed text from the interviews was analyzed using inductive thematic analysis. Two topics were generated and constructed by the researchers: (1) "barriers to the implementation of pain neuroscience education, with subthemes including (a) "current health care approach," (b) "basic curriculum and continuing education," (c) "patients' barriers"; (2) "facilitators to the implementation of pain neuroscience education," with subthemes containing (a) "interest in the BPS model, (b) "therapeutic alliance," and (c) "motivation for future training on BPS approach." The analysis of the results showed that Lebanese physical therapists currently hold a strong biomedical view of chronic pain, assessment, and treatment. However, despite the presence of barriers and challenges, they are aware and open to consider the implementation and future training about the BPS model and pain neuroscience education in their approach. The exploration of potential barriers and facilitators to the bio-psychosocial model and pain neuroscience education implementation may provide an opportunity for better development and design of a culturally sensitive pain neuroscience education material for Arab-speaking and Lebanese physical therapists. The exploration of barriers and facilitators to the implementation of pain neuroscience education will help to improve pain education and ensure better clinical pain management. The most important barriers were the dominant characteristic of the Lebanese physical therapist's health approach, which is focused on a biomechanically oriented model, and their lack of knowledge to approach chronic pain from a biopsychosocial perspective.

Introduction: Prayer is the most common therapy used in alternative medicine1. The objective of this study was to explore the effect of prayers on endogenous pain modulation, pain intensity, and sensitivity in healthy religious participants. Methods: Two hundred and eight healthy religious participants were enrolled in this study and randomly distributed into two groups, a prayer group (n = 156) and a poem reading or control group (n = 52). Participants from the prayer group were allocated to either an active prayer group (n = 94) receiving an active type of praying or to a passive prayer group (n = 62) receiving a passive type of praying. Pain assessments were performed prior to and following the prayer or poem reading interventions and included pressure pain threshold assessment, conditioned pain modulation, and a numerical pain rating scale for perceived pain intensity. Results: A significant group-by-time interaction for PPT (p = 0.014) indicated post-intervention increases in PPT in the prayer group but not in the poem reading control group. Also, a significant group-by-time interaction for PPT (p = 0.005) indicated that these effects were greater in the active prayer group than in the passive prayer group. Participants experienced a decrease in CPM efficacy (p = 0.030) and an increase in pain intensity (p < 0.001) following the interventions, independent of their group allocation. Discussion: The results showed that prayer, irrespective to type, can positively affect pain sensitivity and intensity, but does not influence endogenous pain inhibition. Process evaluation: Future research should focus on understanding the mechanism behind "prayer induced analgesia". [ABSTRACT FROM AUTHOR]

Introduction: There is growing acknowledgement of the benefits of incorporating a bio-psychosocial model of understanding pain within physical therapist practice1. Consequently this has led to an increasing interest in interventions such Pain neuroscience education (PNE). However, pain management strategies developed by clinicians in one culture may not necessarily be understood, appropriate, or effective in another culture2 Methods: This study is part of a broader research in the development of culturally sensitive pain neuroscience education for the Lebanese population. Therefore, the purpose of this paper is to first gain an in-depth understanding of the Lebanese physiotherapists' perceptions towards the management of chronic low back pain as well as the knowledge regarding PNE. A qualitative one-to-one semi-structured interviews with 10 practicing physical therapists were conducted. The transcribed text from the interviews was analyzed using inductive thematic analysis. Results: Several themes were generated, identified, and constructed by the researchers: (1) physiotherapists use of a biomechanical approach. (2) Poor knowledge about the bio-psychosocial approach or PNE. (3) Barrier and facilitation for the implementation of PNE. Discussion: The preliminary results showed a limited knowledge of the bio-psychosocial approach, or PNE, and that the Lebanese physical therapist use more a biomechanical approach in the treatment and assessment of people with chronic low back pain. Process evaluation: The results showed that training is needed for physiotherapists to deliver a broader model of care, and that future research should focus on developing a culturally sensitive PNE material.

Introduction: Although the cause of persistent non-specific low back pain (NSLBP) remains unknown, structural and functional alterations of the brain1 and paravertebral muscles2 have been proposed as underlying mechanisms. To date, it is unknown if improvements through exercise therapy may be attributed to measurable changes in the muscles and/or adaptations in the brain. Therefore, the objective is to examine short and long-term effects of specific skilled motor control training versus unspecific general exercise training. Methods: In this double-blind, randomized controlled clinical trial, 62 recurrent NSLBP patients will be randomly allocated (1:1) to receive either skilled motor training or general exercise training. The primary outcome is LBP-related disability. Secondary measures include: brain structure, structural/functional connectivity, muscle structure, muscle function, and proprioception. Results: We expect changes only after skilled motor training for: brain function (i.e. increased functional connectivity in default mode network and sensory-motor regions), thoracolumbar dissociation and proprioception. In addition, for brain structure (i.e. changed structural connectivity between parieto-and (pre)motor areas and motor cortex reorganization), muscle function (i.e. timing/amplitude of anticipatory/compensatory postural adjustments) and muscle structure (i.e. muscle/fat index, cross-sectional area) we expect changes for both groups, but more pronounced after skilled motor training. More specifically, we expect that changes in muscle structure are training unspecific for superficial trunk muscles, but more pronounced for deep segmental muscles after skilled motor training. Process evaluation: Learning the necessary skills for MRI acquisition and recognizing artefacts took more time than expected. Several MRI sequence alterations were necessary to ensure sufficient image quality. References: 1. Kregel J, Meeus M, Malfliet A, et al.

AbstractPurposeMethodResultsConclusion\nIMPLICATIONS FOR REHABILITATIONThis paper aims to understand the distinctive biopsychosocial aspects and patient perspectives on chronic low back pain in Lebanon, an Arab country with a unique and rich cultural heritage.Qualitative, semi-structured interviews with 12 Lebanese patients purposefully sampled from various governorates. The interviews included participants from different geographic areas and religions. The data underwent analysis through an inductive thematic approach guided by a bounded relativist ontology, a subjectivist epistemology, and a descriptive phenomenological framework. The coding process was managed by computer-assisted qualitative data analysis software (QSR NVivo version 12.0).The researchers identified and constructed two themes: (1) Chronic low back pain: understanding the impact, coping strategies, and communication patterns in lived experiences within the Lebanese context. This theme sheds light on the complexities of pain management and societal influences in Lebanon. (2) Explanatory model of patients living with chronic low back pain in Lebanon. This theme allowed an exploration of the multifaceted narratives of chronic low back pain.This study found that Lebanese individuals attribute chronic low back pain to biomedical factors despite some recognizing psychosocial elements. It emphasizes the need to educate patients on the biopsychosocial model, facilitate better care, and dispel misconceptions.The exploration of patients’ pain perception may provide an opportunity to better develop and design culturally sensitive pain neuroscience education material for Arab-speaking and Lebanese physical therapists.The rehabilitation process should incorporate a balanced biopsychosocial approach, addressing both physical and psychosocial elements of pain, to provide more effective care and outcomes for Lebanese patients who predominantly attribute chronic low back pain to biomedical factors.Lebanese healthcare professionals need to improve communication with Lebanese patients regarding the nature of chronic low back pain, using clear communication to help dispel misconceptions and enhance rehabilitation outcomes.The exploration of patients’ pain perception may provide an opportunity to better develop and design culturally sensitive pain neuroscience education material for Arab-speaking and Lebanese physical therapists.The rehabilitation process should incorporate a balanced biopsychosocial approach, addressing both physical and psychosocial elements of pain, to provide more effective care and outcomes for Lebanese patients who predominantly attribute chronic low back pain to biomedical factors.Lebanese healthcare professionals need to improve communication with Lebanese patients regarding the nature of chronic low back pain, using clear communication to help dispel misconceptions and enhance rehabilitation outcomes.
