J Rehabil Res Dev. 2012;49(9):1421–30. http://dx.doi.org/10.1682/JRRD.2011.07.0121 Slideshow Project DOI:10.1682/JRRD.2011.07.0121JSP 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.
