## Abstract

The invention relates to a device for treating a patient for neurological or muscular pain by neurostimulation comprising a pair of electrodes to be applied externally, ie. to the surface of the skin, in the region of the pain and to apply a current of between 0.2 and 12 mA at a frequency of between 1 and 50 Hz, and preferably between 2 and 10 Hz. Optimal results appear to be achieved when the applied current is between 3 and 10 mA. In use at least one of the electrodes, a stimulating electrode is used to accurately locate the pain and during treatment the electrode is applied to the patient's skin as located using mild pressure, while a stimulating pulse is applied as treatment. This action produces a remarkable and unexpected level of pain relief. The invention extends to a method for the treatment of neurological pain using the above parameters and procedure.

## Claims

### Claim 1

A method for locating and treating chronic or acute pain in a patient, comprising the steps of:
accurately locating an affected nerve of a patient by placing on the skin of the patient a reference electrode in the form of a removable patch, then pressing against the skin of the patient a substantially rounded stimulating electrode of diameter of about 3 to 12 mm, at an end of a rigid stem, and applying between the reference and stimulating electrodes an electrical current;
moving the stimulating electrode to points on the skin to locate an affected, pain-causing nerve based on the reaction of the patient;
applying pressure to the stimulating electrode against the affected nerve simultaneously with applying between the reference and stimulating electrodes stimulating electrical pulses of frequency 1 to 10 Hz, and current between 0.2 and 12 ma;
varying frequency and current of the pulses to optimize pain relief, and
maintaining pressure against the affected nerve for a time sufficient to achieve relief of the pain.

### Claim 2 (depends on 1)

A method as claimed in claim 1, wherein the applied frequency is between 2 and 3 Hz.

### Claim 3 (depends on 2)

A method as claimed in claim 2, wherein the applied current is between 3 and 10 mA.

### Claim 4 (depends on 2)

A method as claimed in any of claim 2, wherein the stimulating pulse is applied for 5 minutes.

### Claim 5 (depends on 2)

A method as claimed in claim 2, wherein a negative current is applied to the stimulating electrode.
