Since rehabilitation treatment does not simply treat a disease, but treats the patient who has a disease, it is not desirable to determine the treatment strategies based soly on the time of onset of a disease. Rehabilitation treatment
should involve carefully evaluating the features of the disease and the patient, which requires considerable time. The convalescent (subacute) period requires a system in which rehabilitation treatment for central nervous system diseases can be administered for at least 2 years. In addition, the definitions and details of rehabilitation treatment that can be conducted by a rehabilitation specialist in the convalescent period and those of rehabilitation treatment conducted in the maintenance (chronic) period should be determined in advance, and these steps should be combined with the development of appropriate provisions in the medical insurance system for each period.
