Abstract
Abstract A method for the treatment, by accelerating the healing process, of acute herpes simplex and acute herpes zoster, and by the reduction of post-herpetic neuralgia, subsequent to determining a dermatone on a body, which dermatome includes an area affected by herpes and which comprises a corresponding segment nerve. Two conducting electrodes are applied to the surface of the dermatome including an anode directly on the spiral ganglion of the most proximal portion of the corresponding nerve, and a cathode on the distal part of the dermatome. Electric current having a constant frequency of about 30 Hz and in the shape of monopolar pulses of an approximately square wave-form having a duration of about 0.2 msec. is applied to the electrodes. The current intensity is adjusted in corresponding with the respective skin resistance.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
156 words
A method for the treatment, by accelerating the healing process, of acute herpes simplex and acute herpes zoster, and by the reduction of post-herpetic neuralgia, subsequent to determining a dermatome on a body, said dermatome including an area affected by herpes and comprising a corresponding sensory segmental nerve, comprising: applying two conducting electrodes to the surface of said dermatome including an anode directly on the spinal ganglion of the most proximal portion of said corresponding nerve, and a cathode on the distal part of said dermatome; supplying said two conducting electrodes with current from a source of electrical current having a constant frequency of about 30 Hz and in the shape of monopolar pulses of an approximately square wave-form having a duration of about 0.2 msec., and adjusting the current intensity in accordance with the respective skin resistance, whereby the healing process of herpes affections is accelerated, and occurrences of herpes and post-herpetic neuralgia are reduced.
Claim 2
Independent Claim
156 words
A method for the treatment, by accelerating the healing process, of acute herpes simplex and acute herpes zoster, and by the reduction of post-herpetic neuralgia, subsequent to determining a dermatome on a body, said dermatome including an area affected by herpes and comprising a corresponding sensory segmental nerve, comprising: applying two conducting electrodes to the surface of said dermatome including an anode directly on the spinal ganglion of the most proximal portion of said corresponding nerve, and a cathode on the distal part of said dermatome; supplying said two conducting electrodes with current from a source of electrical current having a constant frequency of about 30 Hz and in the shape of monopolar pulses of an approximately square wave-form having a duration of about 0.2 msec., and adjusting the current intensity in accordance with the respective skin resistance, whereby the healing process of herpes affections is accelerated, and occurrences of herpes and post-herpetic neuralgia are reduced.
