Most common headaches are either migraine or traction headaches. In patients prone to migraine headaches, traction or tension headaches may be a precipitating or a triggering factor. ALL acute or new onset headaches should be evaluated by a medical doctor. Over 5 million Americans suffer from chronic headaches and current treatment options are limited to symptomatic relief.
Migraine Syndrome: Most of the pain associated with migraine originates in or are involved with the blood vessels located at the base of the brain or in the scalp. Not all structures in the head contain pain-sensing fibers. Therefore, sources of head pain are limited. After the traction component is treated, placement is dependent upon whether vessels which supply blood to the front portion of the brain (anterior circulation) or the back portion (posterior circulation) are involved.
Migraine headaches involving the blood vessels feeding the front of the brain, as well as the back portion of the brain, may be accompanied by symptoms such as cravings for food, elation, hyperactivity, sadness, depression and thirst, all of which may occur hours or even days in advance of an attack. Posterior (back portion) circulation headaches may begin with symptoms such as visual hallucinations, vision loss and a staggering gait or loss of balance.
Anterior Circulation (front of the brain): The device is placed over the temporal area (temple) on the side of the head discomfort. If this involves the entire front of the head, the devices may be placed over the temples on both sides of the head. It is noted from the figure that the QuadraBloc field covers most of the structures that are known to contain pain-sensing fibers in the anterior circulation. If discomfort persists, one additional QuadraBloc may be placed in the middle on the forehead just above the brow line. This location allows the gradient field to cover the base of the anterior arteries and covering of the brain (the dura) which contain pain fibers.
