AI Article Synopsis

  • * Traditional treatments like nonsteroidal anti-inflammatory drugs and opioids can lead to serious side effects and may not provide enough relief for many patients.
  • * Recent research on neurotrophic factors, particularly the glial cell line-derived neurotrophic factor (GDNF) family, offers insights into potential new therapies targeting these signaling pathways for better pain management.

Article Abstract

Chronic musculoskeletal pain is highly prevalent and poses a significant personal, societal, and economic burden. Management of chronic musculoskeletal pain remains a challenge. Long-term use of common analgesic medications such as nonsteroidal anti-inflammatory drugs and opioids is associated with adverse events, and in the case of opioids, drug addiction. Additionally, many individuals do not experience sufficient pain relief with these therapeutic approaches. Thus, there is an urgent need to develop clinically efficacious and safe therapeutics for musculoskeletal pain. Recent advances in our understanding of musculoskeletal pain neurobiology have helped identify the role of neurotrophic factors, specifically, the glial cell line-derived neurotrophic factor (GDNF) family of ligands (GFL) and their associated signaling pathways. This review outlines our current understanding of the GFL signaling systems, discusses their role in inflammatory and chronic musculoskeletal pain and sensitivity, and comments on the analgesic therapeutic potential of targeting the GFL signaling system.

Background: Usually, patients with hand, wrist/forearm disorders report musculoskeletal complaints in the shoulder. Although, role of scapula is fundamental for movement and functional stability across the upper limb kinetic chain; however, there are no systematic reviews and meta-analyses that have analyzed the effect of scapular exercises in these patients.

Purpose: This study aimed to determine the effectiveness of a scapular exercise program on functional outcomes in patients with hand, wrist or elbow disorders.

Introduction: Ireland's Health Service Executive is developing a new national integrated low back pain (LBP) pathway spanning primary and secondary care to improve LBP healthcare. Clinical pathways are frequently employed to optimise clinical outcomes and resource use but are challenging to implement. Context-specific implementation planning, leveraging implementation science and its conceptual frameworks, should inform successful implementation.

Introduction: The use of virtual reality (VR) in physiotherapy is expanding across various fields; however, while extensively researched in neurology, its application in musculoskeletal (MSK) disorders remains underexplored. This review aims to evaluate the effectiveness of VR in pain management across different anatomical regions.

Materials And Methods: The research was conducted using the MEDLINE (via PubMed), Cochrane Library, Scopus, Web of Science, and Embase databases, including randomized controlled trials that evaluated the effectiveness of VR interventions, encompassing immersive VR, specialised non-immersive VR, and gaming platforms.

Background: Spinal pain affects up to 30% of school-age children and can interfere with various aspects of daily life, such as school attendance, physical function, and social life. Current assessment tools often rely on parental reporting which limits our understanding of how each child is affected by their pain. This study aimed to address this gap by developing MySpineData-Kids ("MiRD-Kids"), a tailored patient-reported questionnaire focusing on children with spinal pain in secondary care (Danish hospital setting).
