Randomized Controlled Trial
Interferential and horizontal therapies in chronic low back pain due to multiple vertebral fractures: a randomized, double blind, clinical study.
Chronic low back pain due to multiple vertebral fractures is of difficult management. Electrical nerve stimulation is frequently used, but its efficacy has never been properly evaluated. In a randomized placebo-controlled clinical trial, we have shown that both interferential currents and horizontal therapy are more effective than placebo for functional. ⋯ This randomized double-blind controlled study provides the first evidence that IFT and HT therapy are significantly effective in alleviating both pain and disability in patients with CBPMF.

The project to develop a new Japanese Orthopaedic Association (JOA) score rating system for low back disorders, the JOA Back Pain Evaluation Questionnaire (JOABPEQ), is currently in progress. Part 1 of the study selected 25 "candidate" items for use on the JOABPEQ. The purpose of this current Part 2 of the study was to verify the reliability of the questionnaire. ⋯ The tentative questionnaire of the JOABPEQ with 25 items was confirmed to be reliable enough to describe the quality of life of patients who suffer low back disorders.

Neuroanatomical pathway of nociception originating in a low back muscle (multifidus) in the rat.
The neural mechanisms of low back pain (LBP) are still enigmatic. Presently, low back muscles are being discussed as an important source of LBP. Here, the neuroanatomical pathway of the nociceptive information from the caudal multifidus muscle (MF) was studied. ⋯ To visualize supraspinal projections, fluorogold (FG) was injected into the contralateral ventrolateral periaqueductal gray (vlPAG) 6 days prior to formalin or saline injection into the MF. The number of double-labeled dorsal horn neurons (FG-positive plus c-Fos-ir) in all lumbar segments was significantly higher in the formalin group than in the saline group. These results show that (1) the origin of the sensory supply of the MF is shifted two segments cranially relative to the location of the muscle, (2) the spinal cells processing nociceptive input from the caudal MF are widely distributed, and (3) the vlPAG is a supraspinal center of nociception from the MF.
