Basic research is advancing the understanding of the pathogenesis and management of low back pain at the molecular and genetic levels. Frequently, low back pain is caused by disorders of the intervertebral disk. ⋯ Recent research using growth factors to promote chondrocyte regeneration appears to be promising. Advances in gene therapy to both prevent disk degeneration and regenerate the disk eventually may have clinical application.

A practice-based study of patients with acute and chronic low back pain attending primary care and chiropractic physicians: two-week to 48-month follow-up.
This study reports pain and disability outcomes up to 4 years for chiropractic and medical patients with low back pain (LBP) and assesses the influence of doctor type and pain duration on clinical outcomes. ⋯ Study findings were consistent with systematic reviews of the efficacy of spinal manipulation for pain and disability in acute and chronic LBP. Patient choice and interdisciplinary referral should be prime considerations by physicians, policymakers, and third-party payers in identifying health services for patients with LBP.

Pain anticipated before and induced by physical activities has been shown to influence the physical performance of patients with chronic back pain. Limited data exist as to the influence of treatment on this component of pain. ⋯ Anticipated and induced pain with physical activities was lessened after physical therapy using exercise. Anticipated and induced pain with physical activities related to physical performance levels, global pain and disability ratings. These findings may help explain how exercise exerts a positive influence on chronic back pain and disability.

It has been reported that rhythmic gymnasts are at risk of suffering from low back injuries, because of repetitive lumbar hyperextensions. On the other hand, this sport requires features of leanness, muscular strength and flexibility that should represent protective factors for back pain. ⋯ Competitive, club-level rhythmic gymnasts show a reduced prevalence of low back-pain. Being younger in age, having greater leanness, not smoking, displaying less anxious/depressive behaviour, and developing increased muscle strength and flexibility, all can represent preventive factors for low back pain. This study suggests that rhythmic gymnastics is not a discipline at increased risk of low back pain.

Comparative Study
Intrathecal drug delivery for treatment of chronic low back pain: report from the National Outcomes Registry for Low Back Pain.
To obtain data on patient demographics, clinical practices, and long-term outcomes for patients with chronic low back pain treated with implantable drug-delivery systems. ⋯ Current clinical practices related to trialing of drug-delivery systems resulted in the majority of patients successfully trialed. At 12-month follow-ups, implanted patients experienced reductions in numeric back and leg pain ratings, improved Oswestry scores, and high satisfaction with the therapy.
