Tongue Body Kinematics in Parkinsons Disease

Parkinsons Disease affects not only gross motor but also speech motor control. Standard treatment options are drug treatment with levodopa and surgical treatment with deep brain stimulation. While both treatments are effective for gross motor symptoms, it is yet to be fully understood how speech responds to levodopa and deep brain stimulation. This thesis investigates the effect of both treatment options on the kinematic, acoustic and perceptual level in the same group of speakers with Parkinsons disease for a first time
