Myofascial pain response to topical lidocaine patch therapy: case report.
This is a case from a preliminary open trial to assess the efficacy of topically applied lidocaine patches as an alternative to trigger point injections for myofascial pain. We describe one case in this report that had a dramatic response to the lidocaine patch. Her pain relief increased, pain intensity decreased, and functional capacity increased. Her pain intensity and relief was measured by the Brief Pain Inventory-Short Form (BPI-SF). A quality of life measure was also included in the BPI-SF. While this was a dramatic response to this patient, it is only one case from an open-trial. The response to other patients has varied. The true clinical utility cannot be obtained from this one report, but only after the data have been analyzed from this initial trial. If the data are promising, a randomized, double-blind, crossover trial is planned.
