Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The investigators tested whether pain decrease can be observed centrally with non-invasive brain imaging in CBP subjects receiving Lidoderm. The investigators first tested effects of 5% Lidoderm patched in an open labelled trial. Next the investigators compared the effects of Lidocaine versus Placebo patches. Three time points were evaluated: baseline (before treatment) and 6 hours and 2 weeks after treatment. The latter trial was a 2 arm, double blind, placebo controlled trial, where participants either received Lidoderm or placebo patches, without cross over.
