These studies examined the Mendelsohn maneuver  and side-lying posture .
The Mendelsohn maneuver was studied in a case series, quasi-experimental study of participants with CVA .
examined the use of the Mendelsohn maneuver in 25 participants with CVA using sEMG to monitor performance of maneuver .
However, data reported from two additional studies suggest this maneuver may not be as effective in preventing aspiration as other interventions, such as the Mendelsohn maneuver [13,15].
The effects of the Mendelsohn maneuver with individuals receiving surgical resection and chemoradiation for postcancer treatment are reported for 24 subjects in three studies [14-15,17].
used the Mendelsohn maneuver with 18 participants with head and neck and 2 with esophageal cancer .
Maneuvers studied included the effortful swallow, the Mendelsohn maneuver
, the supraglottic swallow, and the super-supraglottic swallow.
Maneuvers studied included effortful swallow, the Mendelsohn maneuver, supraglottic swallow, and super-supraglottic swallow.
Three studies examined the Mendelsohn maneuver [15,18,23], three examined the supraglottic swallow [15-16,26], and three examined the super-supraglottic swallow [15,26,30].
The latter reports findings from studies examining five behavioral interventions (chin tuck, effortful swallow, Mendelsohn maneuver, supraglottic swallow, and super-supraglottic swallow) and the impact of these interventions on physiological and functional swallowing outcomes.
The Mendelsohn and effortful swallow maneuvers were attempted under fluoroscopy based on the evidence that the Mendelsohn maneuver reduces aspiration and improves oral intake for individuals with head and neck cancer and that the effortful swallow has an effect on lingual pressures in normal subjects.
The systematic reviews investigated the specific compensatory swallowing postures and maneuvers commonly used by SLPs, including side lying, chin tuck, head rotation, effortful swallow, Mendelsohn maneuver
, supraglottic swallow, and super supraglottic swallow, and examined the impact of these treatments on physiology, functional swallow ability, and pulmonary health for nondisordered healthy adults, neurological populations, and head and neck cancer populations.
