Background: Interventions for low back pain typically produce small and short-term effects. Cognitive functional therapy (CFT) has shown large effects up to 12 months, but long-term effects are unclear. We aimed to compare the long-term (3-year) effectiveness of CFT, delivered with or without movement sensor biofeedback, with usual care for patients with chronic disabling low back pain.

Background: Lumbar spinal stenosis (LSS) affects older people, leading to a decline in functional ability, and its prevalence is projected to rise with the aging population. Effective, affordable, and low-risk interventions are needed to maintain the function and quality of life for LSS patients. This study tested the feasibility of implementing a comprehensive conservative treatment program (Boot Camp Program) for LSS in Danish chiropractic clinics to inform a future randomised clinical trial.

Background: Rehabilitation services are essential health services that should be made available to a population. Measuring effective coverage requires the assessment of whether a population's health services needs are met and whether they are met through quality interventions that produce the desired health gain. We propose a global indicator and corresponding questions to measure effective coverage of rehabilitation through population-based surveys.

Background: Routine seeking of imaging for patients with low back pain is not concordant with the evidence-based recommendation that imaging is rarely of diagnostic value. Inappropriate imaging is a waste of resources and can lead to undesirable downstream effects for individuals and health systems. To develop effective strategies to reduce unwarranted referrals for imaging in primary care, we must understand the drivers for, and barriers to, guideline-adherent practice.

Background Context: Recumbent MRI is the most widely used image modality in people with low back pain (LBP), however, it has been proposed that upright (standing) MRI has advantages over recumbent MRI because of its ability to assess the effects of being weight-bearing. It has been suggested that this produces systematic differences in MRI parameters and differences in the correlation between MRI parameters and pain or disability in patients thus, potentially adding clinically helpful information.

Purpose: This paper aims to review and summarize the available empirical evidence for or against these 2 hypotheses.

Background: While technology brings many opportunities for optimizing and improving health services, the lack of professionals trained in telehealth poses an important obstacle. Despite the existance of core competency frameworks for some healthcare professions, there is currently no consensus or guidelines on the core competencies that telehealth professionals should possess within the context of a higher education curriculum. This can hinder the potential benefits of healthcare service delivery.

Background: One in three women and one in five men over the age of 50 will experience an osteoporotic fracture. Vertebral fractures can be very painful, affect patients' daily function, and in severe cases require hospitalization. Traditionally, fracture pain is treated conservatively with analgesics, and bracing.

Advancements in clinical science have shown the necessity for a paradigm shift away from a biomedical toward a biopsychosocial approach. Yet, the translation from clinical science into clinical practice is challenging. The aim of this study was to assess the short-term and mid-term changes in pain knowledge and attitudes and guideline-adherent recommendations of healthcare professionals (HCP) by means of an interdisciplinary training program (ITP) about chronic pain.

Article Synopsis
  • The study aimed to evaluate the relationship between sedentary behavior and spinal pain in children and adolescents, focusing on the direction and strength of this association, risk of pain onset, and prognosis.
  • The systematic review analyzed 129 reports, revealing a small positive association between sedentary behavior and spinal pain in cross-sectional studies, but no significant risk of pain onset in longitudinal studies.
  • The findings suggest that while there may be a slight correlation, sedentary behavior does not necessarily cause spinal pain, and more research is needed to understand its impact on pain prognosis.

Pain is a challenge in persons with OI and causes much concern in the Osteogenesis Imperfecta (OI) population. We aim to evaluate the usability of the Nordic Musculoskeletal Questionnaire (NMQ) to identify painful sites in adults with OI and to describe the occurrence of musculoskeletal (MSK) pain and its impact on their work and daily activities. This cross-sectional pilot study uses the OI-NMQ to study MSK pain prevalence in nine separate anatomical regions (neck, upper back, lower back, shoulder, elbow, hand/wrist, hip, knee, and ankle/foot) and its impact on regular work and daily activities in adults with OI.
