Fundamental Frequency Characteristics of Parkinsonian Speech after Subthalamic Nucleus Deep Brain Stimulation

This study investigated the effects of the subthalamic nucleus deep brain stimulation (STN-DBS) on fundamental frequency (F0) of parkinsonian speech and the validity of different tasks in exploring the effectiveness of STN-DBS for parkinsonian speech. Ten STN-DBS treated patients participated this study and speech recordings including sustained vowel /a/, repeated syllables /pha/ and reading speech were collected after their surgery in three states, namely stimulation off one month after operation (OFF), stimulation on after internal pulse generator (IPG) on for one month (ON1) and stimulation on after IPG on for three months (ON2) respectively. All these states were under the state of medication off. Results showed that there were significant increases in F0 range and F0 variability of reading speech between OFF and ON2. The positive effect of STN-DBS on parkinsonian speech may be a chronic process and the benefit only manifests in reading speech which indicates a careful consideration of task when evaluating speech ability of PD patients.
