To assess whether magnetic resonance (MR) imaging has replaced other diagnostic imaging modalities in the evaluation of persistent low back pain. ⋯ MR imaging was used primarily as an add-on rather than a substitute for other imaging modalities in the evaluation of persistent low back pain. Thus, the volume and cost of diagnostic imaging for persistent low back pain have increased.

A cross-sectional study. ⋯ When the appropriate technique is used, medial branch blocks are target specific. To guard against false-negative responses due to intravenous up-take, contrast medium must be used before the injection of local anaesthetic.

Randomized Controlled Trial Multicenter Study Clinical Trial
Local and remote sustained trigger point therapy for exacerbations of chronic low back pain. A randomized, double-blind, controlled, multicenter trial.
A randomized, double-blind, controlled, multicenter trial was conducted. ⋯ Neuroreflexotherapy intervention seems to be a simple and effective treatment for rapid amelioration of pain episodes in patients with chronic low back pain. At this time, the duration of pain relief beyond 45 days has not been evaluated.

Clinical TrialSomatotosensory evoked potentials during baroreceptor stimulation in chronic low back pain patients and normal controls.
Nineteen chronic low back pain patients (aged 19-63) and 17 controls (aged 20-41) received electrical pain stimuli during manipulation of their carotid baroreceptors. The non-invasive mechanical manipulation of baroreceptors, using the PRES technique (Phase Related External Suction), simulates the end-effects of phasic blood pressure changes. This technique was developed to assess pain responses induced by changes in blood pressure without the typical shortcomings of pharmacological manipulation or lack of a control condition. ⋯ Results showed that lower tonic blood pressures are associated with greater baroreceptor activity amplifying pain, while higher blood pressure is associated with pain dampening during high baroreceptor activity. Data suggested that the differences in pain responses found in low back pain patients were associated with their lower tonic blood pressure levels. It is proposed that in general, lower blood pressures may be associated with greater pain during baroreceptor activation.

Case Reports[Transcutaneous radiofrequency destruction of the articular nerves in treating low back pains].
Lumbar pain is a most common suffering which frequently becomes chronic. In the mechanical low back syndrome caused by an abnormality in the intervertebral joints, lumbar pain may be rather easily differentiated from pain induced by to spinal root compression due to discal hernia or intervertebral foramen stenosis. The absence of benefits from conservative treatment of lumbar pain caused by intervertebral joint abnormalities is an indication for the highly effective and low-traumatic surgical technique transcutaneous radiofrequency destruction of intervertebral facette nerves. The technique yields good results in small displacements of the lumbar vertebra which cannot undergo orthopedic interventions, as well as in severe vertebral deformities which cause a higher load on the intervertebral joints.
