“…Several studies have described the regions to touch for testing sensation: a patient's aryepiglottic folds (Langmore et al, 1988;Leow, Beckert, Anderson, & Huckabee, 2012;Onofri et al, 2014), arytenoids (Langmore et al, 1988;Onofri et al, 2014) or epiglottis (Langmore et al, 1988). Studies have reported five acceptable positive responses to the touch of an endoscope: patient report when they feel the touch (Kaneoka, Krisciunas, Walsh, Raade, & Langmore, 2015;Leow et al, 2012;Sato et al, 2002), an LAR (Domer, Kuhn, & Belafsky, 2013;Onofri et al, 2014), a cough, a gag, or a swallow (Langmore et al, 1988;Leow et al, 2012). However, several issues remain unclear regarding the touch method.…”
