Importance: Although mindfulness-based interventions (MBIs) are evidence-based treatments for chronic pain and comorbid conditions, implementing them at scale poses many challenges, such as the need for dedicated space and trained instructors.

Objective: To examine group and self-paced, scalable, telehealth MBIs, for veterans with chronic pain, compared to usual care.

Design, Setting, And Participants: This was a randomized clinical trial of veterans with moderate to severe chronic pain, recruited from 3 Veterans Affairs facilities from November 2020 to May 2022.

Background: Randomized clinical trials (RCTs) are the gold standard for assessing treatment effectiveness; however, they have been criticized for generalizability issues such as how well trial participants represent those who receive the treatments in clinical practice. We assessed the representativeness of participants from eight RCTs for chronic spine pain in the U.S.

Article Synopsis
  • PTSD and chronic pain often occur together in veterans, leading to worse outcomes for those who experience both conditions compared to having either one alone.
  • This study aimed to explore if there are any gender differences in how PTSD symptoms affect pain outcomes in veterans with chronic pain.
  • The results showed that PTSD symptoms are linked to increased pain-related issues for both men and women veterans, with no significant gender differences found in the impact of PTSD on pain outcomes.

Background: Post-traumatic stress disorder (PTSD) and chronic pain are highly prevalent comorbid conditions. Veterans dually burdened by PTSD and chronic pain experience more severe outcomes compared to either disorder alone. Few studies have enrolled enough women Veterans to test gender differences in pain outcomes [catastrophizing, intensity, interference] by the severity of PTSD.

Meta-analysis is commonly used to combine results from multiple clinical trials, but traditional meta-analysis methods do not refer explicitly to a population of individuals to whom the results apply and it is not clear how to use their results to assess a treatment's effect for a population of interest. We describe recently-introduced causally interpretable meta-analysis methods and apply their treatment effect estimators to two individual-participant data sets. These estimators transport estimated treatment effects from studies in the meta-analysis to a specified target population using the individuals' potentially effect-modifying covariates.

Background: Chronic low back pain (cLBP) is widespread, costly, and burdensome to patients and health systems. Little is known about non-pharmacological treatments for the secondary prevention of cLBP. There is some evidence that treatments addressing psychosocial factors in higher risk patients are more effective than usual care.

Background: Chronic low back pain (cLBP) affects the quality of life of 52 million Americans and leads to an enormous personal and economic burden. A multidisciplinary approach to cLBP management is recommended. Since medication has limited efficacy and there are mounting concerns about opioid addiction, the American College of Physicians and American Pain Society recommend non-pharmacological interventions, such as mind and body approaches (e.

Objective: To explore whether using a single matched or composite outcome might affect the results of previous randomized controlled trials (RCTs) testing exercise for non-specific low back pain (NSLBP). The first objective was to explore whether a single matched outcome generated greater standardized mean differences (SMDs) when compared with the original unmatched primary outcome SMD. The second objective was to explore whether a composite measure, composed of matched outcomes, generated a greater SMD when compared with the original primary outcome SMD.

Background: Low back pain (LBP) is influenced by interrelated biological, psychological, and social factors, however current back pain management is largely dominated by one-size fits all unimodal treatments. Team based models with multiple provider types from complementary professional disciplines is one way of integrating therapies to address patients' needs more comprehensively.

Methods: This parallel group randomized clinical trial conducted from May 2007 to August 2010 aimed to evaluate the relative clinical effectiveness of 12 weeks of monodisciplinary chiropractic care (CC), versus multidisciplinary integrative care (IC), for adults with sub-acute and chronic LBP.

Objectives: Despite several hundred previous randomised controlled trials (RCTs), the key treatment targets of exercise for persistent non-specific low back pain (NSLBP) remain unclear. This study aimed to generate consensus about the key treatment targets of exercise interventions for patients with NSLBP.

Design: Consensus was generated using modified nominal group technique in two, sequential, workshops.

Background: 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.

Objectives: This study will test two approaches to delivering MBIs for improving Veterans' chronic pain and mental health comorbidities.

Article Synopsis
  • Low back pain (LBP) is a frequent and debilitating issue for older adults, and while spinal manipulative therapy (SMT) has shown minor improvements compared to standard medical care, its effectiveness when added to home exercise needs further investigation.
  • A randomized clinical trial included 241 older adults with sub-acute or chronic LBP to compare the effects of SMT and supervised rehabilitative exercise added to home exercise over 12 weeks, focusing on pain severity and other health outcomes.
  • Results indicated that while all treatment groups experienced a 30-40% reduction in pain, the differences between SMT, rehabilitative exercise, and home exercise alone were small and not statistically significant, suggesting that adding these therapies might not lead to better long-term

Background: Spinal pain is a common and disabling condition with considerable socioeconomic burden. Spine pain management in the United States has gathered increased scrutiny amidst concerns of overutilization of costly and potentially harmful interventions and diagnostic tests. Conservative interventions such as spinal manipulation, exercise and self-management may provide value for the care of spinal pain, but little is known regarding the cost-effectiveness of these interventions in the U.

Objective: Back and neck pain are associated with disability and loss of independence in older adults. Whether long-term management using commonly recommended treatments is superior to shorter-term treatment is unknown. This randomized clinical trial compared short-term treatment (12 weeks) versus long-term management (36 weeks) of back- and neck-related disability in older adults using spinal manipulative therapy (SMT) combined with supervised rehabilitative exercises (SRE).

Article Synopsis
  • - Low back pain (LBP) is common among adolescents, but there is limited high-quality research on effective treatments. A study compared spinal manipulative therapy (SMT) combined with exercise therapy (ET) to ET alone in 185 adolescents aged 12 to 18 with chronic LBP over 12 weeks and tracked outcomes for up to a year.
  • - Results showed that adding SMT to ET led to a greater reduction in LBP severity over time, especially noticeable at 26 weeks and 52 weeks. The combination also resulted in improved disability and higher patient satisfaction compared to exercise therapy alone.
  • - Overall, the study suggests that SMT combined with exercise is more effective for managing chronic low back pain in adolescents than exercise

Background Context: The optimal number of visits for the care of cervicogenic headache (CGH) with spinal manipulative therapy (SMT) is unknown.

Purpose: The present study aimed to identify the dose-response relationship between visits for SMT and chronic CGH outcomes and to evaluate the efficacy of SMT by comparison with a light-massage control.

Study Design/setting: This is a two-site, open-label randomized controlled trial.

Background: In order for measurements to be clinically useful, data on psychometric conditions such as reliability should be available in the population for which the measurements are intended to be used. This study comprises a test-retest design separated by 7 to 14 days, and evaluates the intra and interrater reliability of regional frontal and horizontal spinal motion in 219 chronic LBP patients using the CA6000 Spine Motion Analyzer. In addition, it compares these results on the frontal and horizontal plane with previously published results on the sagittal plane.
