No. 1. 107-119 Korean Journal of Oriental Medicine Original Article Clinical Research on the rehabilitation of Stroke patients’ motor ability Chang-Nam Ko, Sang-Kwan Moon, Ki-Ho Cho, Young-Suk Kim, Hyung-Sub Bae, Kyung-Sub Lee Department of Cardiovascular and Neurological diseases(Storke center) Kyunghee University, Seoul, Korea Abstract Background and Purpose: This clinical study investigated the effect of oriental medical treatment (herbal medicine, acupuncture & moxibustion therapy, physiotherapy, etc.) for the motor recovery improvement in stroke patients. The MBI (Modified Barthel Index) and NIHSS (National Institute of Health Stroke Scale) were used to evaluate the motor recovery in these patients. Methods: We selected the 151 stroke patients (79 male and 72 female) who visited Kang Nam Korean Hospital, Kyunghee University from June 1. 2000 to June 30. 2001 and investigated their characteristics, risk factors, past history, lesion area and size, symptoms, admission period and the period from onset to admission. We analyzed the MBI & NIHSS records to prove the efficacy of oriental medical treatment. Results and conclusions: Age distribution shows in 60s, 70s, 50s, 40s and 80s. The average age was 65.6±10.0. Gender ratio was 1.09:1(M:F). Lesion areas were mostly in the MCA (Middle Cerebral Artery), multifocal, brainstem and PCA (Posterior Cerebral Artery). Antecedent diseases of stroke patients were hypertension (78.4%), heart diseases, and diabetes mellitus, prior attacks. Symptoms of these patients are motor disturbance, verbal disturbance, swallowing disturbance and stool and urine disturbance. The mean admission period was 35.3±36.2 days. The significant period from onset to admission was 23.6 ±42.8 days. Correlation with lipid profile of stroke was not significant. Analyzing the MBI & NIHSS, MBI records showed significant negative correlation in age, admission period and the period from onset to admission (p<0.01). The NIHSS record was significant positive correlation in admission period at admission (p<0.01) and positive correlation with admission period at discharge (p<0.05). DIF-MBI shows significant positive correlation with admission period (p<0.01). In score improvement of the MBI & NIHSS, the MBI showed such a significant improvement in cerebral infarction and hemorrhage (p<0.01). The NIHSS shows significant improvement in cerebral infarction (p<0.05).

Besides, its high functionality level is very low. Thus, NIHSS return rate makes stoke one of the major concerns (National Institute of Health Stroke Scale) has not only by the health and medical authorities but been used as an assessment tool for those patients also by the entire country. who are in an acute phase of stroke5-8). In general, the functional rehabilitation of stoke Considering the fact that the number of oriental patients is based on the recovery of their motor medical clinics has rapidly increased so has the ability and this has become an important expectation and interest in the cure of stroke by theoretical propose since Twitchel treated stroke oriental medicine, it is time that systematic clinical patients and evaluated their status based on their research should be undertaken in order to prove rehabilitation stage in 1951. In 1970s, the motor the effectiveness of oriental medicine on stroke in ability assessment of stroke patients has become an objective way. This study aims to evaluate the more recognized along with the development of effectiveness of oriental medical treatments Brunnstrom’s research and various nervous or including the use of oriental medicines, physiological clinic methods2). Although it is acupuncture, moxibustion and physiotherapies to important to precisely evaluate the current status cure stroke patients by using the MBI (Modified of disorders and estimate the possibility of Barthel Index) and the NIHSS (National Institute rehabilitation, it is also necessary to set a realistic of Health Stroke Scale), which are most com- goal of treatment ensuring positive effectiveness monly used as a functionality assessment tool. due to the fact that disorders distressing stroke patients differ from one patient to another and their Objects & Methodology of the complications also present individual aspects.
