Abstract

AIM: To investigate microelectrode recording (MER)-induced microlesion effect (MLE) on the motor symptoms of 30 patients with Parkinson's disease (PD) who underwent deep brain stimulation of the subthalamic nucleus.

MATERIAL and METHODS: MER-induced MLE was evaluated based on the difference between tremor, rigidity, and bradykinesia scores in the preoperative off-state and intraoperative state following MER and before test stimulation.

RESULTS: MLE scores improved by 21.7% [left (L) side] and by 13.6% [right (R) side] from baseline (p 0.05).

CONCLUSION: MER-induced MLE improved motor symptoms and was not correlated with the number of microelectrodes used during the procedure.
