Objectives : This study aims to evaluate the current status of clinical use of diagnostic equipment in oriental neuropsychiatry. Methods : Thirty clinical studies using diagnostic equipment out of 223 papers in the journal of oriental neuropsychiatry in the 10 years from 2003 to 2012 were reviewed. Results : Ten diagnostic apparatuses were used in 30 papers. HRV (Heart Rate Variability) was used the most, but the results of papers were not consistent. ADS (ADHD Diagnostic System) and ERP (Event Related Potential) were effective in clinical research. Conclusions : Diagnostic equipment might be useful and effective to treat mental disorders if they are to be used properly and followed by well-designed studies.
