Changes in coordination of postural control during dynamic stance in chronic low back pain patients.
The human postural system operates on the basis of integrated information from three independent sources: vestibular, visual and somatosensory. It is conceivable that a derangement of any of these systems will influence the overall output of the postural system. The peripheral proprioceptive system or the central processing of proprioceptive information may be altered in chronic low back pain (CLBP). ⋯ Control experiments ruled out that increased sway was due to pain interference. In CLBP patients, postural stability under challenging conditions is maintained by an increased sway in AP direction. This change in postural strategy may underlie a dysfunction of the peripheral proprioceptive system or the central integration of proprioceptive information.

Magnetic resonance (MR) imaging is frequently used to evaluate first-time episodes of serious low back pain (LBP). Common degenerative findings are often interpreted as recent developments and the probable anatomic cause of the new symptoms. To date no prospective study has established a baseline MR status of the lumbar spine in subjects without significant LBP problems and prospectively surveyed these subjects for acute changes shortly after new and serious LBP episodes. This method can identify new versus old MR findings possibly associated with the acute symptomatic episode. ⋯ Findings on MR imaging within 12 weeks of serious LBP inception are highly unlikely to represent any new structural change. Most new changes (loss of disc signal, facet arthrosis, and end plate signal changes) represent progressive age changes not associated with acute events. Primary radicular syndromes may have new root compression findings associated with root irritation.

A small-scale exploratory cross-sectional survey investigated the current use of a range of exercise therapy approaches for low back pain (LBP) by outpatient physiotherapists in the acute hospital setting in the Republic of Ireland, where the majority of publicly funded treatment is delivered. Of the 120 postal questionnaires distributed to 24 physiotherapy departments, 87 were returned (72.5% response rate). ⋯ The most popular forms of exercise therapy used by outpatient physiotherapists in acute hospital settings in Ireland lack support from evidence-based clinical guidelines, and further large-scale high quality randomized controlled trials of these approaches are warranted. Further research should also establish the use of exercise therapy and attitudes to clinical guidelines of physiotherapists in other countries and healthcare settings.

This is a retrospective study of 250 patients who describe low back pain with pain drawings. A computer application using artificial neural networks was designed to analyze pain drawings and evaluate the contribution of pain sensation to drawing classification. ⋯ Patient-reported pain sensation does not improve classification when quantitatively scoring pain drawings.

Beyond needling--therapeutic processes in acupuncture care: a qualitative study nested within a low-back pain trial.
In the medical and scientific literature, there is a dearth of reports about how acupuncturists work and deliver care in practice. An informed characterization of the treatment process is needed to support the appropriate design of evaluative studies in acupuncture. ⋯ This study suggests that acupuncture care for patients with chronic conditions such as low back pain is likely to be a complex intervention that utilizes a number of patient-centered strategies to elicit longterm therapeutic benefits. Research designed to evaluate the effectiveness of acupuncture as it is practiced in the UK needs to accommodate the full range of therapeutic goals and related treatment processes.
