Spring 2014 Colloquium Series: Prof. Doug Whalen

Spring 2014 Colloquium Series:  with Dr. Doug Whalen CUNY, Department of Speech-Language-Hearing Sciences Using ultrasound to assess tongue flexibility in Parkinson’s disease Parkinson’s disease (PD) is a neurological disorder characterized by the degeneration of dopaminergic neurons. Speech impairments in PD are characterized by slowed muscle activation, muscle rigidity, variable rate, and imprecise consonant articulation. Complex muscular synergies are necessary to coordinate tongue motion for linguistic purposes.  I will present an overview of some mathematical techinques for comparing tongue shapes, and then apply those techniques to two samples of ultrasound measures of tongue shape in PD patients and age-matched controls.  Preliminary results indicate some differentiation between the groups in the measures, as well as matches to perceptual assessment of impairment, but more refined measures are called for in order to be of use in diagnosis or assessment of disease progression.
