Randomized Controlled Trial Comparative Study Clinical Trial
Efficacy of cognitive therapy for chronic low back pain.
The effects of outpatient group cognitive therapy, relaxation training, and cognitive therapy in combination with relaxation training on chronic low back pain and associated physical and psychosocial disability were evaluated and compared. One-hundred and two mildly disabled chronic low back pain patients were assigned randomly to a waiting-list (WL) control condition and the 3 treatments. ⋯ Depressive symptoms and disability improved significantly in all conditions (including the waiting list) from pretreatment to post-treatment, with no statistically significant differences among treatments. At both follow-ups, all 3 treatment groups remained significantly improved from pretreatment, with no statistically significant differences between treatments.

Randomized Controlled Trial Clinical Trial
A randomized double-blind trial of dextrose-glycerine-phenol injections for chronic, low back pain.
This randomized clinical trial evaluated the efficacy of injections of a dextrose-glycerine-phenol connective tissue proliferant into the posterior ligaments, fascia, and joint capsules to treat chronic low back pain. Seventy-nine patients with chronic low back pain that had failed to respond to previous conservative care were randomly assigned to receive a double-blind series of six injections at weekly intervals of either Xylocaine/saline solution or Xylocaine/proliferant into the posterior sacroiliac and interspinous ligaments, fascia, and joint capsules of the low back from L4 to the sacrum. Patients were observed with a visual analog, disability, and pain grid scores, and with objective computerized triaxial tests of lumbar function for 6 months following conclusion of injections. ⋯ Improvements in visual analog (p = 0.056), disability (p = 0.068), and pain grid scores (p = 0.025) were greater in the proliferant group. Objective testing of range of motion, isometric strength, and velocity of movement showed significant improvements in both groups following treatment but did not favor either group. The MRI and CT scans showed significant abnormalities in both groups, but these did not correlate with subjective complaints and were not predictive of response to treatment.

Randomized Controlled Trial Clinical TrialThe Hmax/Mmax ratio as an outcome measure for acute low back pain.
To evaluate the use of the Hmax/Mmax (H/M) ratio as an outcome measure for acute low back pain and to determine the change of this ratio in acute low back pain patients treated with spinal manipulation. ⋯ The H/M ratio was found to be within normal limits in subjects with acute low back pain. The H/M ratio showed greater change in the group which received spinal manipulation, but the change was subtle. The results indicate that the H/M ratio may be of limited value in clinical practice.

Randomized Controlled Trial Clinical TrialTreatment of pelvic joint dysfunction in primary care--a controlled study.
The study evaluated the manual treatment of dysfunction of the pelvic joints. This is one of many condition causing low back pain. In 1987-1988 a general practitioner with special knowledge of physical examination and manual treatment of lumbar and pelvic dysfunctions made a survey of patients with acute or subacute low back pain as the main cause of the patient-to-doctor contact. ⋯ After a period of three weeks, evaluation was made by an independent observer. Subjective pain measurement and a mobility test showed no significant difference. Sick-leave and consumption of analgesics (both decided by patient) were significantly less in the treatment group.

Randomized Controlled Trial Clinical Trial
Persistent low-back pain is real. However, diagnostic spinal injections are not helpful in its evaluation.
We endeavored to assess the short-term effects of intrathecal fentanyl and lidocaine in chronic-pain patients by ascertaining whether the opioid fentanyl, by virtue of its lack of sensory and motor paralysis, conferred any diagnostic advantages over lidocaine, a local anesthetic whose effects include sensory and motor paralysis. Neuraxial administration of fentanyl has been touted as an improved diagnostic tool to distinguish between peripheral and central pain, because the absence of sensory and motor effects may avert the patient's presumption of the onset of analgesia based on these cues. Twenty-two patients with persistent low-back pain, whose investigations had determined that they were not surgical candidates, were studied using a counter-balanced, placebo-controlled, and double-blinded crossover design. ⋯ There were no significant differences in the baseline median-pain scores among injection types. The baseline and best cerebrospinal fluid-pain scores were significantly different, suggesting a placebo effect. The best pain scores for fentanyl and lidocaine were superior to their own baseline levels and to the best cerebrospinal fluid scores.(ABSTRACT TRUNCATED AT 250 WORDS)
