Equipment
Acoustics
Acoustic measures can provide objective data on vocal function.
Aerodynamics
Data on lung pressures and laryngeal airflows help to assess physiologic vocal function
Electroglottography
EGG measures vocal fold contact across time.
Laryngeal Imaging
Laryngeal endoscopy procedure and stroboscopy technique help to visualize the oral, nasal, and laryngeal structures along with vocal fold motion and function during voicing, breathing, and other vegetative gestures.
Surface Electromyography
The sEMG is a non-invasive technique to investigate muscle activity during the swallow function. This can also be used for biofeedback purposes.
IOPI
Iowa Oral Performance Instrument helps to objectively measure the strength and endurance of two articulators - lips and tongue
