Abstract

OBJECTIVE
The authors analyzed the findings of microelectrode recording data and reported the surgical outcomes of movement disorder patients.
METHODS
Since February 2000, the authors have used DBS for the movement disorders. We evaluated 4 patients who were followed more than 12 months after operation. One patient with essential tremor was treated with thalamic stimulation and three patients with idiopathic advanced Parkinson's disease with bilateral subthalamic nucleus stimulation. The electrodes were inserted under microelectrode recording. Clinical assessments were performed preoperatively and postoperatively by neurologist.
RESULTS
All features of parkinsonian symptoms improved and the greatest benefit occurred in off-time and ADL. Interestingly our three patients with advanced Parkinson's disease did not have off-time after bilateral stimulation of subthalamic nucleus. There were no adverse side effects related to microelectrode recording or DBS procedure in all 4 patients. In our results of microelectrode recording of subthalamic nucleus, subthalamus showed higher firing rate than that of substantia nigra pars reticularis. Mean burst frequency of subthalamic nucleus was much higher than that of substantia nigra pars reticularis.
CONCLUSION
The first trials of DBS in Korea also demonstrated favorable outcomes for movement disorders.
