Abstract


Objective
This study aimed at providing a critical review of the overall benefits of the chin-tuck maneuver through a systematic review of its effects when used in the treatment of dysphagia, as well as to provide basic data for a comparative analysis in future studies.
Methods
To identify academic papers on the chin-tuck maneuver published from January 2000 to January 2021, a literature search on three databases was performed using keywords, including chin-tuck, dysphagia, and head flexion. Out of the 712 related papers identified, the methodological characteristics and results of 12 selected studies were reviewed.
Results
Nine of the 12 studies found that the chin-tuck position not only helped in the opening of the upper esophageal sphincter (UES) but also reduced pharyngeal residues and prevented aspiration and penetration. In addition, three studies analyzed the position of the neck flexion angle and the changing angle when performing the chin-tuck maneuver.
Conclusion
This shows that the chin-tuck maneuver is an effective strategy in the treatment of dysphagia. In future studies, further investigation of the posture, angles, and effects of the chin-tuck maneuver, could help identify additional benefits of this treatment.
