Article Synopsis
  • - Chronic primary low back pain (CPLBP) lasts over 3 months without a clear cause and is linked to emotional distress; previous research highlights spinal manipulative therapy (SMT) as a potentially effective treatment.
  • - A recent study with 98 individuals suffering from CPLBP tested the efficacy of SMT over 12 sessions compared to a control group, measuring pain intensity and various psychological factors.
  • - Results showed that SMT significantly reduced pain intensity but not disability, with a noted decrease in local hyperalgesia and pain catastrophizing, suggesting that while SMT is beneficial, understanding the psychological impacts requires further investigation.

Corticosteroids are commonly used in the treatment of inflammatory low back pain, and their nominal target is the glucocorticoid receptor (GR) to relieve inflammation. They can also have similar potency at the mineralocorticoid receptor (MR). The MR has been shown to be widespread in rodent and human dorsal root ganglia (DRG) neurons and non-neuronal cells, and when MR antagonists are administered during a variety of inflammatory pain models in rats, pain measures are reduced.

Swimming Anatomy and Lower Back Injuries in Competitive Swimmers: A Narrative Review.

Sports Health

November 2024

Harvard Spaulding Rehabilitation Hospital, Department of Physical Medicine and Rehabilitation, Harvard Medical School, Boston, Massachusetts.

Context: Competitive swimmers are at high risk of overuse musculoskeletal injuries due to their high training volumes. Spine injuries are the second most common musculoskeletal injury in swimmers and are often a result of the combination of improper technique, high loads on the spine in strokes that require hyperextension, and repetitive overuse leading to fatigue of the supporting trunk muscles. The purpose of this review is to summarize the current evidence regarding swimming biomechanics, stroke techniques, and common injuries in the lumbar spine to promote a discussion on the prevention and rehabilitation of lower back injuries in competitive swimmers.

Millions of people worldwide suffer from low back pain and disability associated with intervertebral disc (IVD) degeneration. IVD degeneration is highly correlated with aging, as the nucleus pulposus (NP) dehydrates and the annulus fibrosus (AF) fissures form, which often results in intervertebral disc herniation or disc space collapse and related clinical symptoms. Currently available options for treating intervertebral disc degeneration are symptoms control with therapy modalities, and/or medication, and/or surgical resection of the IVD with or without spinal fusion.
