Data for: Voice tremor outcomes of subthalamic nucleus and zona incerta deep brain stimulation in patients with Parkinson’s disease

The assessed samples in the data set were prolonged vowels produced by Parkinson's disease patents off or on deep brain stimulation (DBS). The two targets evaluated were the subthalamic nucleus and the caudal zona incerta. Each row presents the results presents information regarding one rating of a sample. The information provided is the rated voice tremor severity (on a 0-3 scale, 3 is severe voice tremor), number of replays and delay time information, along with a rater identifier and a rating session ID. All assessments were performed in a blinded and randomized manner using the Alvin 2 stimulus presentation software. Hillenbrand, J. M., & Gayvert, R. T. (2005).
