Review Meta AnalysisRadiofrequency denervation for neck and back pain. A systematic review of randomized controlled trials.
The diagnosis of cervical or lumbar zygapophyseal joint pain can only be made by using local anesthesia to block the nerves supplying the painful joint. There is a lack of effective treatment for chronic zygapophyseal joint pain or discogenic pain. Radiofrequency denervation appears to be an emerging technology, with substantial variation in its use between countries. ⋯ The selected trials provide limited evidence that radiofrequency denervation offers short-term relief for chronic neck pain of zygapophyseal joint origin and for chronic cervicobrachial pain; conflicting evidence on the short-term effect of radiofrequency lesioning on pain and disability in chronic low-back pain of zygapophyseal joint origin; and limited evidence that intradiscal radiofrequency thermocoagulation is not effective for chronic discogenic low-back pain. There is a need for further high-quality RCTs with larger patient samples and data on long-term effects, for which current evidence is inconclusive. Furthermore, RCTs are needed in non-spinal indications where radiofrequency denervation is currently used without any scientific evidence.

Review Meta AnalysisWork conditioning, work hardening and functional restoration for workers with back and neck pain.
Physical conditioning programs, variously called work conditioning, work hardening and functional restoration/exercise programs, aim to improve work status and function. Previous attempts have been made to evaluate the efficacy of work-oriented back pain management programs, but none have focused exclusively on work or functional outcomes. ⋯ Physical conditioning programs that include a cognitive-behavioural approach plus intensive physical training (specific to the job or not) that includes aerobic capacity, muscle strength and endurance, and coordination; are in some way work-related; and are given and supervised by a physiotherapist or a multidisciplinary team, seem to be effective in reducing the number of sick days for some workers with chronic back pain, when compared to usual care. However, there is no evidence of their efficacy for acute back pain.

Meta Analysis Comparative Study
[Acupuncture for back pain: meta-analysis of randomised controlled trials and an update with data from the most recent studies].
Acupuncture is commonly used to treat back pain. A meta-analysis of clinical trials of acupuncture for this condition came to a positive conclusion whilst a qualitative review was negative. ⋯ Collectively, these data imply that acupuncture is superior to various control interventions, although there is insufficient evidence to state whether it is superior to placebo.

Back pain is a common problem for which cyclobenzaprine hydrochloride is frequently prescribed. ⋯ Cyclobenzaprine is more effective than placebo in the management of back pain; the effect is modest and comes at the price of greater adverse effects. The effect is greatest in the first 4 days of treatment, suggesting that shorter courses may be better. Studies comparing the relative value of acetaminophen, nonsteroidal anti-inflammatory drugs, and cyclobenzaprine individually and in combination in the treatment of back pain are needed.

Meta Analysis
Teasing apart quality and validity in systematic reviews: an example from acupuncture trials in chronic neck and back pain.
The objectives of the study were (1) to carry out a systematic review to assess the analgesic efficacy and the adverse effects of acupuncture compared with placebo for back and neck pain and (2) to develop a new tool, the Oxford Pain Validity Scale (OPVS), to measure validity of findings from randomized controlled trials (RCTs), and to enable ranking of trial findings according to validity within qualitative reviews. Published RCTs (of acupuncture at both traditional and non-traditional points) were identified from systematic searching of bibliographic databases (e.g. MEDLINE) and reference lists of retrieved reports. ⋯ OPVS is a useful tool for assessing the validity of trials in qualitative reviews. With acupuncture for chronic back and neck pain, we found that the most valid trials tended to be negative. There is no convincing evidence for the analgesic efficacy of acupuncture for back or neck pain.
