The use of electronic biofeedback for the management of post-herpetic neuralgia--a report of 3 cases.

The purpose of these case reports is to describe treatment of three consecutive patients with post-herpetic neuralgia using a bioelectronical device (SCENAR). The instrument is approved as a Class II device in the United States. The electrode of the device was stroked gently over the involved skin area for up to 15 minutes per session. No more than 5 sessions over a 3-week period was required. All patients experienced substantial relief of pain from the first treatment. One patient required only 1 treatment lasting 10 minutes. The other 2 patients required 4 to 5 treatments over a 3-week period. One patient required a treatment for skin itch after one year with a follow up period of 6 months to 24 months. An electronic biofeedback device (SCENAR) may be successfully utilized in the management of post-herpetic neuralgia.
