J Rehabil Res Dev. 2012;49(9):1421–30. Slideshow Project DOI: /JRRD JSP Aim – Establish: Whether ultrasound (US) stimulation can safely stimulate cough. Most efficient US frequency. Whether single- or dual-sided stimulation is more effective. Relevance – Ability to cough voluntarily is absent or diminished in many clinical situations, which may predispose patients to or prolong respiratory diseases.

J Rehabil Res Dev. 2012;49(9):1421–30. Slideshow Project DOI: /JRRD JSP Results Nondisabled subjects – Cough stimulated: 80% at 0.58 MHz and 9 W unilaterally. 75% at 0.58 MHz and 6 W bilaterally Unable-to-cough subjects – Cough stimulated: 71% at 0.54 MHz and 6 W bilaterally.
