Randomized Controlled Trial
Pain Physiology Education Improves Health Status and Endogenous Pain Inhibition in Fibromyalgia: A Double-Blind Randomized Controlled Trial.
There is evidence that education on pain physiology can have positive effects on pain, disability, and catastrophization in patients with chronic musculoskeletal pain disorders. A double-blind randomized controlled trial (RCT) was performed to examine whether intensive pain physiology education is also effective in fibromyalgia (FM) patients, and whether it is able to influence the impaired endogenous pain inhibition of these patients. ⋯ These results suggest that FM patients are able to understand and remember the complex material about pain physiology. Pain physiology education seems to be a useful component in the treatment of FM patients as it improves health status and endogenous pain inhibition in the long term.

Randomized Controlled Trial
Botulinum Toxin A in Postherpetic Neuralgia: A Parallel, Randomized, Double-Blind, Single-Dose, Placebo-controlled Trial.
Cumulative evidence support a beneficial effect of botulinum toxin A (BTX-A) in postherpetic neuralgia (PHN). We aimed to assess efficacy, safety, and tolerability of BTX-A in the management of PHN, performing a randomized, double-blind, single-dose, placebo-controlled trial. ⋯ Data confirm that BTX-A is effective and well tolerated in the treatment of PHN.
