Chronic low back pain (cLBP) has been associated with changes in brain plasticity. Non-pharmacological therapies such as Manual Therapy (MT) have shown promise for relieving cLBP. However, translational neuroimaging research is needed to understand potential central mechanisms supporting MT. We investigated the effect of MT on resting-state salience network (SLN) connectivity, and whether this was associated with changes in clinical pain. Fifteen cLBP patients, and 16 matched healthy controls (HC) were scanned with resting functional Magnetic Resonance Imaging (fMRI), before and immediately after a MT intervention (cross-over design with two separate visits, pseudorandomized, grades V 'Manipulation' and III 'Mobilization' of the Maitland Joint Mobilization Grading Scale). Patients rated clinical pain (0-100) pre- and post-therapy. SLN connectivity was assessed using dual regression probabilistic independent component analysis. Both manipulation (Pre: 39.43 ± 16.5, Post: 28.43 ± 16.5) and mobilization (Pre: 38.83 ± 17.7, Post: 31.76 ± 19.4) reduced clinical back pain (p<0.05). Manipulation (but not mobilization) significantly increased SLN connectivity to thalamus and primary motor cortex. Additionally, a voxelwise regression indicated that greater MT-induced increase in SLN connectivity to the lateral prefrontal cortex was associated with greater clinical back pain reduction immediately after intervention, for both manipulation (R=-0.8) and mobilization (R=-0.54). Our results suggest that MT is successful in reducing clinical low back pain by both spinal manipulation and spinal mobilization. Furthermore, this reduction post-manipulation occurs via modulation of SLN connectivity to sensorimotor, affective, and cognitive processing regions. Perspective: Manual Therapy both reduces clinical low back pain and modulates brain activity important for the processing of pain. This modulation was shown by increased functional brain connectivity between the salience network and brain regions involved in cognitive, affective, and sensorimotor processing of pain.
Learn More >Mindfulness-based interventions (MBIs) are evidence-based nonpharmacological treatments for treating chronic pain. However, the predominant MBI, mindfulness-based stress reduction, has features that pose significant implementation barriers.
Learn More >Percutaneous peripheral nerve stimulation (PNS) is an analgesic modality involving the insertion of a lead through an introducer needle followed by the delivery of electric current after needle withdrawal. This modality has been used extensively to treat chronic pain, but only small series have been published involving postoperative pain. The ultimate objective of this study is to determine the postoperative effects of percutaneous PNS following moderately to severely painful ambulatory surgery within a real-world clinical practice setting. The primary hypothesis is that surgical pain and opioid consumption during the initial 7 days after surgery will be reduced by percutaneous PNS compared with usual and customary analgesia (dual primary outcome measures).
Learn More >Manualized cognitive and behavioral therapies are increasingly used in primary care environments to improve nonpharmacological pain management. The Brief Cognitive Behavioral Therapy for Chronic Pain (BCBT-CP) intervention, recently implemented by the Defense Health Agency for use across the military health system, is a modular, primary care-based treatment program delivered by behavioral health consultants integrated into primary care for patients experiencing chronic pain. Although early data suggest that this intervention improves functioning, it is unclear whether the benefits of BCBT-CP are sustained. The purpose of this paper is to describe the methods of a pragmatic clinical trial designed to test the effect of monthly telehealth booster contacts on treatment retention and long-term clinical outcomes for BCBT-CP treatment, as compared with BCBT-CP without a booster, in 716 Defense Health Agency beneficiaries with chronic pain.
Learn More >The Defense Health Agency has prioritized system-level pain management initiatives within the Military Health System (MHS), with low back pain as one of the key focus areas. A stepped care model focused on nonpharmacologic treatment to promote self-management is recommended. Implementation of stepped care is complicated by lack of information on the most effective nonpharmacologic strategies and how to sequence and tailor the various available options. The Sequential Multiple-Assignment Randomization Trial for Low Back Pain (SMART LBP) is a multisite pragmatic trial using a SMART design to assess the effectiveness of nonpharmacologic treatments for chronic low back pain.
Learn More >Chronic lower back pain is a highly prevalent medical condition in Western countries, which that incurs a considerable social and economic burden. Although prescription exercise at home for chronic pain has become a widely used alternative to reduce healthcare costs, the evidence regarding patient adherence and decreased in costs in European countries is scarce and inconclusive. The objective of this study is to examine the cost-utility and cost-effectiveness in patients with chronic lower back pain treated with the McKenzie Method and electroanalgesia via a telemedicine programme versus a face-to-face programme.

Learn More >Many health care systems are beginning to encourage patients to use complementary and integrative health (CIH) therapies for pain management. Many clinicians have anecdotally reported that patients combining self-care CIH therapies with practitioner-delivered therapies report larger health improvements than do patients using practitioner-delivered or self-care CIH therapies alone. However, we are unaware of any trials in this area.

Learn More >(1) Background: Chronic musculoskeletal pain (CMP) in adolescents can negatively affect physical, psychological, and social functioning, resulting in functional disability. This randomized controlled trial (RCT) aimed to evaluate the effectiveness of an outpatient rehabilitation program based on graded exposure in vivo (EP) compared with care as usual (CAU: interdisciplinary outpatient rehabilitation care). Both EP and CAU aim to improve functional ability in adolescents with CMP. (2) Methods: Pragmatic multicenter RCT with 12-month follow-up. Adolescents (12-21 years) with CMP were invited to participate. Primary outcome: functional disability; secondary outcomes: perceived harmfulness; pain catastrophizing; pain intensity. Data analysis: intention-to-treat linear mixed model. (3) Results: Sixty adolescents (mean 16 years) were randomized; data for 53 were analyzed. Adolescents in EP showed relevant and significant decreases in functional disability (estimated mean difference at least -8.81, ≤ 0.01) compared with CAU at all times. Significant differences in favor of EP were found for perceived harmfulness at all times ( ≤ 0.002), for pain catastrophizing at 2 months ( = 0.039) and for pain intensity at 4 and 10 months ( ≤ 0.028). (4) Conclusion: EP leads to a significant and clinically relevant decrease in functional disability compared with usual care.
