Cerebrovascular disease is a major unsolved medical problem. It is the third leading cause of death in persons over 45 years of age, ranking only behind heart disease and cancer, and it is the foremost crippler of all diseases in the United States (1-2). I n the face of such a challenge, there is a remarkable void in our knowledge of the subject despite extensive current clinical and laboratory research. Perhaps more serious is the fact t h a t the physician tends t o view with despair the plight of the stroke patient. Although the clinician is fully aware of the patient's potential for deterioration, he may be unfamiliar with estimating the potential for improvement and with devising a n individualized program of total rehabilitation.
