Percutaneous neuromodulation therapy (PNT) is a new minimally invasive, office-based treatment for low back pain in which electrical stimulation is delivered to the paraspinal peripheral nerves. The purpose of this study was to determine the safety, tolerability, and clinical efficacy of PNT in a population of patients with subacute low back pain with radiation to the lower extremity. ⋯ For many patients with subacute radiating low back pain, PNT significantly reduced pain and self-rated disability, and improved sleep quality and activity level. PNT is safe and generally well tolerated.

Neuropathic low back pain is examined from a structural standpoint, distinguishing processes that start from chronic inflammation and mechanical compromise and cross into the realm of neuropathy with primary neurogenic pathophysiology. The disease of chronic pain is discussed, examining peripheral and central changes in neuroanatomy, neurophysiology, and neuromolecular dynamics. The limitations of inadequate random controlled trials regarding long-term pharmacologic interventions are contrasted with excellent work in the basic science of chronic pain. Complex rational pharmacologic strategies for structural pathology, central pain processes, sites of medication action, and differing routes of administration are delineated.

Skeletal scintigraphy of young patients with low-back pain and a lumbosacral transitional vertebra.
Lumbosacral transitional vertebrae can alter the biomechanics of weight transfer at the affected spinal segment. Low-back pain may result. This study assessed what skeletal scintigraphy reveals about stress associated with a lumbosacral transitional vertebra in young patients with low-back pain. ⋯ Skeletal scintigraphy often indicates stress at the transverse-sacral articulation of young patients with low-back pain and a lumbosacral transitional vertebra. Showing evidence of stress is best accomplished using SPECT. Changes are usually not radiographically evident, but there is a trend for MRI and CT to show findings that imply stress or motion at the articulation. The unique ability of skeletal scintigraphy to provide this physiologic information supports its use in these patients.

Patient satisfaction, characteristics, radiology, and complications associated with attending a specialized government-funded multidisciplinary spinal pain unit.
To prospectively document the satisfaction of a random sample of patients attending a specialized multidisciplinary spinal pain unit in the Australian public health care system and to collect associated data on patient characteristics, radiological findings, treatment modalities used, and any significant complications. Design and setting Spinal pain syndrome patients attended the specialized Multidisciplinary Spinal Pain Unit at Townsville General Hospital and the Kirwan Community Health Centre (Queensland, Australia) for diagnosis and management (ie, chiropractic spinal manipulation, medication, or needle acupuncture). A patient satisfaction questionnaire was sent to a random sample of patients in this Queensland Government funded service that was approved by the health authority's Ethics Committee. ⋯ A public hospital or community health center based specialized spinal pain syndrome unit is useful for referring clinicians who wish to obtain a further opinion for challenging spinal pain syndrome patients in the lower socioeconomic group that cannot afford private health care.
