 Chin-tuck posture is a frequently used compensatory technique to prevent aspiration for patients with dysphagia by altering the shape of the pharynx and the location of the laryngeal structures as well as swallowing biomechanics. It has been reported that patients with incomplete laryngeal closure or delayed onset of swallowing may best benefit from this compensatory maneuver. However, chin-tuck posture reduces pharyngeal pressure during swallowing, and specifically with the head flexion position, the duration of the upper esophageal sphincter opening is shortened. Thus, employing this compensatory technique may increase the residue in the pyriform sinus, which can overflow into the larynx after swallow. Most of previous research studies on chin-tuck posture have not reported the specific head/neck position based upon the functional anatomies (i.e. head flexion, neck flexion, or head and neck flexion) employed in their investigations. Few studies have specified the head position used in their investigations; moreover, the study participants were limited to healthy adults. Future studies are warranted to examine if those findings from the healthy adults could be generalized to patients with dysphagia.
