Simple and quick non-invasive evaluation of circulatory condition of cerebral arteries by clinical application of the "Bi-Digital O-Ring Test".

Omura Y.

Using the "Bi-Digital O-Ring Test," generalized abnormal circulation of the distribution of the 3 cerebral arteries at each side of the brain (i.e., anterior cerebral artery, middle cerebral artery and posterior cerebral artery) can be predicted, without any expensive instruments usually in a few minutes. When abnormality was found in the bifurcation area of the common carotid artery by the "Bi-Digital O-Ring Test," there were always abnormal findings of the area of the brain where circulation was coming from either one or both of the anterior or middle cerebral arteries. When abnormal "Bi-Digital O-Ring" response was found at the vertebral artery and posterior cerebral artery representation point, discovered by the author, at the side of the 6th cervical vertebra (corresponding to the entry point of the vertebral artery into the transverse foramen), the areas of the cerebrum, cerebellum and brain stem where circulation is coming from the posterior cerebral artery, basilar artery and vertebral artery were also abnormal. Most of these abnormalities were found to be associated with problems of the cervical vertebrae and spastic muscles of the neck and shoulders and are often reversible. In this study, the author was able to differentiate abnormal brain circulation of any major branch of arteries in the brain due to organic changes or functional reversible changes by relaxing these spastic muscles and improving the circulation of the neck and shoulder area by giving either manual acupuncture, massage, or transcutaneous electrical stimulation. This in turn often improved brain circulation. If it was a functional abnormality, within a few minutes after one of these procedures the "Bi-Digital O-Ring Test" usually showed normal response or improvement. However, if it was an organic abnormality, the abnormality remained. When the supra-orbital arterial blood pressure at both sides of the forehead decreases below 40 or 30 mmHg, most patients develop so-called "Cephalic Hypotension Syndrome," which is characterized by sleep disturbance pattern; difficulty in concentration; easy forgetfulness of recent events; irritability; decreased pain threshold with or without depression; spastic skeletal muscles, particularly the neck, shoulder and back areas. All of these symptoms can be explained by decreased circulation to the Nucleus Raphe Centralis Superior (controls sleep and waking pattern), Nucleus Raphe Magnus (serotonin & modulation of pain), Nucleus Reticularis Giganto Cellularis (controls muscle tone), etc. in reticular formation.(ABSTRACT TRUNCATED AT 400 WORDS)
