Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Radiofrequency denervation of lumbar facet joints in the treatment of chronic low back pain: a randomized, double-blind, sham lesion-controlled trial.
Radiofrequency facet joint denervation procedures have been common practice for 2 decades in treatment of chronic low back pain. We designed this multicenter, randomized, double-blind, sham treatment controlled trial to determine the efficacy of radiofrequency facet joint denervation, as it is routinely performed. ⋯ The combined outcome measure and VAS showed no difference between radiofrequency and sham, though in both groups, significant VAS improvement occurred. The global perceived effect was in favor of radiofrequency. In selected patients, radiofrequency facet joint denervation appears to be more effective than sham treatment.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Local steroid injections for tennis elbow: does the pain get worse before it gets better?: Results from a randomized controlled trial.
To compare the early effects of local corticosteroid injection, naproxen, and placebo as treatments for tennis elbow in primary care. Specifically, to find out whether the extra pain reduction experienced by patients who are given the steroid injection in the short-term would be realized within the first 5 days of treatment and to attempt to assess how much extra pain may be associated with the injection initially. ⋯ Steroid injection was associated with an increase in reported pain for the first 24 hours of treatment, but the therapeutic benefits compared with naproxen and placebo were evident 3 to 4 days after the start of treatment.
