Objective : In 1983 Autosomal dominent spinocerebellar ataxia(ADCA) has been classified to four types by a useful clinical features according to Harding. Since 1993 ADCA referred to as SCA by molecular genetic characteristics. We focused on the improvement of clinical symptoms in SCA patient through oriental medical treatment. Methods ＆ Results : The assessment included neurophysiological examination and clinical symptoms. For example slow saccade, gaze limitation, upward and lateral, nystagmus, truncal and gait ataxia. The patient(M/30) was clinically charaterized by ocular abnormalities, trunkal and gait ataxia and the MRI showed atrophy of cerebellar vermis. The patient was taken both common acupuncture and Dong-Si venepuncture on Hwasan with herbal medicine. Before the treatment Rt. ocular movement were slowed and a significant eye fixation was observed always in abduction and intermittently presented trunkal and gait ataxia. During the treatment trunkal and gait ataxia has not been presented and ocular obnomalities changed to normal state. This case suggests the possibility of oriental medical treatment on SCA but further observation is needed on this patient.
