A system for elucidating physiological characteristics of laryngeal adductor reflex (LAR) responses in a human or animal subject's larynx's vocal folds (VFs) includes a pressure pulsing component to provide a stable and adjustable pulse of pressure to the larynx, a control system component in functional communication with the pressure pulsing component to control or regulate one or more aspects of the timing, magnitude and number of pulses of pressure delivered by the pressure pulsing component during respiratory cycles, and a respiratory sensor component to detect and/or determine physiological characteristics of the subject's LAR response. The method includes evoking a LAR response in the subject and determining one or more physiological measurements including duration, velocity, and angles of motion of the subject's VFs during the LAR response. The present disclosure provides for enhanced endoscopic field of view of the larynx and delivering stimuli over a wider range of controlled parameters.
