Randomized Controlled Trial Comparative Study Clinical Trial
Mini-intervention for subacute low back pain: two-year follow-up and modifiers of effectiveness.
Randomized controlled trial. ⋯ Mini-intervention is an effective treatment for subacute LBP. Despite lack of a significant effect on intensity of low back pain and perceived disability, mini-intervention, including proper recommendations and advice, according to the "active approach," is able to reduce LBP-related costs. The perceived risk of not recovering was the strongest modifier of treatment effect. In alleviating pain, the intervention was most effective among the patients with a high perceived risk of not recovering.

Randomized Controlled Trial Comparative Study Clinical TrialThe short- and long-term benefit in chronic low back pain through adjuvant electrical versus manual auricular acupuncture.
Acupuncture is an established adjuvant analgesic modality for the treatment of chronic pain. Electrical stimulation of acupuncture points is considered to increase acupuncture analgesia. In this prospective, randomized, double-blind, controlled study we tested the hypothesis that auricular electroacupuncture (EA) relieves pain more effectively than conventional manual auricular acupuncture (CO) in chronic low back pain patients with insufficient pain relief (visual analogue scale [VAS] > or = 5) treated with standardized analgesic therapy. Disposable acupuncture needles were inserted in the auricular acupuncture points 29, 40, and 55 of the dominant side and connected to a newly developed battery-powered miniaturized stimulator worn behind the ear. Patients were randomized into group EA (n = 31) with continuous low-frequency auricular EA (1 Hz biphasic constant current of 2 mA) and group CO (n = 30) without electrical stimulation (sham-electroacupuncture). Treatment was performed once weekly for 6 wk, and in each group needles were withdrawn 48 h after insertion. During the study period and a 3-mo follow-up, patients were asked to complete the McGill questionnaire. Psychological well being, activity level, quality of sleep, and pain intensity were assessed by means of VAS; moreover, analgesic drug consumption was documented. Pain relief was significantly better in group EA during the study and the follow-up period as compared with group CO. Similarly, psychological well-being, activity, and sleep were significantly improved in group EA versus group CO, the consumption of analgesic rescue medication was less, and more patients returned to full-time employment. Neuropathic pain in particular improved in patients treated with EA. There were no adverse side effects. These results are the first to demonstrate that continuous EA stimulation of auricular acupuncture points improves the treatment of chronic low back pain in an outpatient population. ⋯ Continuous electrical stimulation of auricular acupuncture points using the new point stimulation device P-stim significantly decreases pain intensity and improves psychological well-being, activity, and sleep in chronic low back pain patients.

Randomized Controlled Trial Clinical Trial
Onset of pain relief with rofecoxib in chronic low back pain: results of two four-week, randomized, placebo-controlled trials.
We recently reported the efficacy of rofecoxib in two randomized controlled trials in chronic low back pain (CLBP). The objectives of this report are to present data regarding the onset of efficacy of rofecoxib from these trials and propose methods for reporting onset. ⋯ Approximately 2/3 of patients achieved meaningful pain relief with rofecoxib time to onset of meaningful relief was about 2 days, but superior relief over placebo was seen by bedtime after the first dose. Onset of perceptible pain relief was within 2 h. We propose that measures of onset of analgesic effect include the proportion of patients who achieve meaningful pain relief and in this subgroup, the time-to-onset of confirmed meaningful reduction in pain intensity, time-to-onset of confirmed pain relief, and time to first separation from placebo in the proportion of patients who achieve meaningful pain relief.

Review Randomized Controlled Trial Multicenter Study Comparative Study Clinical TrialDoes early imaging influence management and improve outcome in patients with low back pain? A pragmatic randomised controlled trial.
To establish whether the early use of sophisticated imaging techniques influences the clinical management and outcome of patients with low back pain (LBP) and whether it is cost-effective. ⋯ The early use of sophisticated imaging does not appear to affect management overall but does result in a slight improvement in clinical outcome at an estimated cost of 870 British pounds per QALY. Imaging was associated with an increase in clinicians' diagnostic confidence, particularly for non-specialists. Further research is required to determine if more rapid referral to sophisticated imaging and secondary care is important in the acute episode and whether the use of imaging would be more beneficial for particular categories of LBP.

The use of intradiscal steroid therapy for lumbar spinal discogenic pain: a randomized controlled trial.
A prospective randomized study of the therapeutic effect of intradiscal steroid injection compared to a saline placebo. ⋯ This study demonstrates that intradiscal steroid injections do not improve the clinical outcome in patients with discogenic back pain compared with placebo.
