A clinical method for the detection and quantification of quick respiratory hyperkinesia.
OBJECTIVE
Quick respiratory hyperkinesia can be difficult to detect with the naked eye. A clinical method is described for the detection and quantification of quick respiratory hyperkinesia.


METHODS
Flow at the airway opening is sensed during spontaneous apnea (rest), voluntary breath holding (postural fixation), and voluntary volume displacement (intentional movement). The method is designed to reveal quick respiratory hyperkinesia independent of the function of the larynx and/or upper airway. Theory underlying the method is discussed, and a protocol is offered for clinical use.


CONCLUSIONS
This method may be useful to neurologists, pulmonologists, and speech-language pathologists. Because it depends on nonspeech observations, its application to speech and/or voice production must be inferred.
