The purpose of study is for the defining the diagnostic criteria of Jung-Pung (中風) which are confused or unclear partially or Oriental Medicine. The results were obstained as follows ; 1. The Diagnosis of Jung-Pung (中風) can be accomplished by the name of disease, symptomatic classification, Byun-Jeung (辨證), stage, assessment of neurological deficit. 2. The various expressive way on the names of Jung-Pung (中風) can be unified as Jung-Pung (中風). 3. The symptomatic classification of Jung-Pung (中風) can be Jung-Kyung-Rak (中經絡) and Jung-Jang-Bu (中臟腑) by unconsciousness. 4. The subclassification of Jung-Kyung-Rak(中經絡) is Kanyangpokhang Punghwa sangyo (肝陽暴亢 風火上擾證), PungDamErHyul BiJoMaecRak (風痰瘀血 痺阻脈絡證), DamYeolBusil PoongDamSangYo (痰熱腑實 風痰上擾證), KiHerhyulEr (氣虛血瘀證), YeumHer PungDong (陰虛風動證) and Jung-Jang-Bu (中臟腑) is PungHwa SangYo CheongGeu (風火上擾淸竅證), DamSeupMongSac ShimSin (痰濕蒙塞心神證), DamYeolNaeFe ShimGeu (痰熱內閉心竅證), WonKiFaeTal ShimSinChakRan(元氣敗脫心神錯亂證) 5. The classification of stages can be divided as stroke stage, convalescent stage, complicated deficit stage. 6. In Oriental Medicine there were few assessment methods of neurological deficit. Therefore we need to develop new assessment system or modification of Western Medicine. The Standardization in the diagnosis of Jung-Pung (中風) has not been well established, even though we had have many clinical experiences. So it is necessary to make a accurate diagnosis that can be done by multiple diagnostic assessment. Therefore the accurate diagnosis of Jung-Pung (中風) can be done by 5 factors, they are the name of diagnosis, symptomatic classification, Byun-Jeung (辨證), stage, the assessment of neurological dificit. And it can be applied in the planning of treatment.
