Randomized Controlled Trial
Efficacy of transcutaneous electrical nerve stimulation (tens) for chronic low-back pain in a multiple sclerosis population: a randomized, placebo-controlled clinical trial.
This study was designed to investigate the hypoalgesic effects of self-applied transcutaneous electrical nerve stimulation (TENS) on chronic low-back pain (LBP) in a multiple sclerosis (MS) population. ⋯ Although not statistically significant, the observed effects may have implications for the clinical prescription and the use of TENS within this population.

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.

Influence of needle position on lumbar segmental nerve root block selectivity.
In patients with chronic low back pain radiating to the leg, segmental nerve root blocks (SNRBs) are performed to predict surgical outcome and identify the putative symptomatic spinal nerve. Epidural spread may lead to false interpretation, affecting clinical decision making. Systematic fluoroscopic analysis of epidural local anesthetic spread and its relationship to needle tip location has not been published to date. Study aims include assessment of epidural local anesthetic spread and its relationship to needle position during fluoroscopy-assisted blocks. ⋯ The findings suggest (P = .06) that the risk of grade 1 and 2 lumbar epidural spread, which results in decreased SNRB selectivity, is greater with medial needle positions in the intervertebral foramen. The variability in anatomic position of the dorsal root ganglion necessitates electrostimulation to guide SNRB in addition to fluoroscopy.

Controlled Clinical Trial
Contribution of nonspinal comorbidity to low back pain outcomes.
To determine the involvement of comorbidity to outcomes in a cohort of acute mechanical low back pain patients. ⋯ Significant ORs were barely greater than 1.00 and were likely the result of the large sample size. The clinical course for comorbid patients, who may seem more complicated at the start of treatment, is just as favorable.

To evaluate reliability, validity and responsiveness of the Fear-Avoidance Beliefs Questionnaire (FABQ) for use in Norwegian patients with low back pain. ⋯ The Norwegian FABQ version had acceptable factor structure, internal consistency, test-retest reliability and construct validity. The responsiveness of the FABQ-Work was low, and for the FABQ-PA moderate, in the acute sample.
