Facilities

The Oral Dynamics Lab is dedicated to research in the area of oral motor control. The lab is equipped with state-of-the-art technology to record and process physiological and physical aspects of speech and swallowing. The main pieces of equipment used in a variety of studies include:

• 3D Electromagnetic Articulograph (EMA)
• Ariel Performance Analysis System (APAS; 3D video motion analysis system)
• Electromyography (EMG)

   

  EMG: Electromyograph records the electrical activity of muscles involved in speech and swallowing.

• Electroglottography (EGG)

   

  EGG: Two-channel electroglottograph with microphone and preamplifier. Records the degree of vocal cord contact during phonation.

• Respitrace

   

  Respitrace: Inductive plethysmography non-invasively measures respiratory kinematics.

• Electropalatography (EPG)

   

  EPG: Electropalatography records tongue-palate contacts.

• force measuring equipment (ELF)

   

  ELF: Economic Load and Force system measures static forces of lips, jaw, or tongue.

• acoustic analysis (Praat)

   

  PRAAT: Acoustic analysis program developed by Boerma & Weenink, 1998. Click here to download a tutorial written by Dr. Van Lieshout that introduces the basic functions.

• Biofeedback System (Thought Technology Infiniti)

   

  Infiniti: Capable of simultaneously tracking skin conductance/temperature, respiration, EMG, electrocardiography (ECG, EKG) and blood volume pulse (BVP). Click here to visit the manufacturer’s website.
