Randomized Controlled Trial Multicenter Study Comparative Study Clinical TrialParenteral dipyrone versus diclofenac and placebo in patients with acute lumbago or sciatic pain: randomized observer-blind multicenter study.
Two hundred and sixty patients with lumbago or sciatic pain participated in a multicenter observer-blind randomized trial to compare the efficacy and tolerability of dipyrone 2.5 g, diclofenac 75 mg, and placebo administered as an intramuscular injection once daily for the duration of one to two days. The effectiveness of the test treatments in relieving sciatic pain was measured by a visual analog scale (VAS) before and 30 minutes, 1, 2, 3, 6 and 24 hours after each injection. In addition, the patient's general well-being was measured on a 5-point rating scale on day 0, 1 and 2. ⋯ Pain intensity on VAS (primary endpoint) showed a significantly greater reduction with dipyrone than with diclofenac or placebo between 1 and 6 hours after application (p < 0.01) and at the end of the trial (after 48 hours). Improvement in general well-being and minimal finger-toe distance was greatest in the dipyrone group. 59% of the patients with dipyrone assessed the overall efficacy as "excellent" or "very good", compared with 30% with diclofenac, and 18% with placebo. Adverse reactions were reported in only 7 patients (3%), 4 (5%) in the dipyrone, 1 (1%) in the diclofenac, and 2 (2%) in the placebo group.

Randomized Controlled Trial Clinical Trial
[Neuro-reflexotherapy intervention in the treatment of non specified low back pain: a randomized, controlled, double-blind clinical trial].
Nonspecific low back pain is a very common disorder for which no completely satisfactory treatment has been established. A randomized, double-blind, controlled clinical trial was design to assess the efficacy of neuro-reflexotherapic intervention in the treatment of this condition. ⋯ According to results of this study, neuro-reflexotherapic intervention has proved to be an effective method for treating low back pain.

Randomized Controlled Trial Comparative Study Clinical Trial
The natural course of acute sciatica with nerve root symptoms in a double-blind placebo-controlled trial evaluating the effect of piroxicam.
To study the natural history of acute sciatica, 208 patients with obvious symptoms and signs of a lumbar radiculopathy (L5 and S1) were examined within 14 days of onset. A concomitant double-blind investigation of the effect of the nonsteroidal anti-inflammatory drug piroxicam was performed. ⋯ Based on questionnaires at months 3 and 12 approximately 30% of the patients still complained about back trouble and 19.5% were out of work after 1 year. Four patients underwent surgery during this period.

Randomized Controlled Trial Clinical Trial
Is TENS purely a placebo effect? A controlled study on chronic low back pain.
Although high-frequency low-intensity transcutaneous electric nerve stimulation (TENS) has been extensively used to relieve low back pain, experimental studies of its effectiveness have yielded contradictory findings mainly due to methodological problems in pain evaluation and placebo control. In the present study, separate visual analog scales (VAS) were used to measure the sensory-discriminative and motivational-affective components of low back pain. Forty-two subjects were randomly assigned to 1 of 3 groups: TENS, placebo-TENS, and no treatment (control). ⋯ This additive effect was not found for placebo-TENS. When evaluated at home, pain intensity was significantly reduced more by TENS than placebo-TENS 1 week after the end of treatment, but not 3 months and 6 months later. At home evaluation of pain unpleasantness in the TENS group was never different from the placebo-TENS group.(ABSTRACT TRUNCATED AT 250 WORDS)

Randomized Controlled Trial Multicenter Study Clinical TrialManual therapy with steroid injections in low-back pain. Improvement of quality of life in a controlled trial with four months' follow-up.
To compare prospectively the effect of manual treatment such as manipulation, specific mobilization, muscle stretching, auto-traction, and cortisone injections with standardized conventional but optimized activating treatment by primary health care teams. ⋯ Manual treatment with steroid injections was superior to conventional treatment in minimizing mental and somatic symptoms and increasing quality of life, in parallel with other measures of improvement.
