<unk>  <unk> , also called peripheral<unk>  stimulation (PNS) of the<unk><unk> s, is used to treat chronic migraine patients who have failed to respond to pharmaceutical treatments. The treatment involves the use of mild electrical impulses to stimulate the greater<unk><unk>  and lesser<unk><unk>  which are part of the peripheral<unk> us system and are located at the back of the head just above the neck area. The electrical impulses are generated by a small device called a neurostimulator – similar to an artificial cardiac pacemaker – which is implanted in the buttock, chest, low abdomen, beneath the shoulder blade or below the clavicle. The electricity is delivered to the greater<unk><unk>  and lesser<unk><unk>  by small metal electrodes which are arranged on thin leads and implanted just under the skin. The intensity of the electrical impulses can be adjusted using a small remote control device.
