Which therapy has been shown to prolong UES opening duration effectively?

• A. Thermotactile stimulation
• B. Mendelsohn maneuver
• C. Chin-down posture
• D. Thickened liquids

Answer: (B)

The Mendelsohn maneuver is a therapeutic technique that has been shown to effectively prolong upper esophageal sphincter (UES) opening duration. This maneuver involves coordinating the timing of swallowing with the elevation of the larynx and prolonging the swallowing reflex, allowing for a more extended and effective opening of the UES. During the maneuver, the individual is instructed to swallow while consciously keeping their larynx elevated momentarily after the swallow. This practice encourages greater control and efficiency with swallowing, which is particularly beneficial for individuals with dysphagia, as it helps reduce the risk of aspiration and improves bolus passage. In contrast, while other techniques may have their own benefits for swallowing, they do not specifically target the prolongation of UES opening duration in the same way. For example, thermotactile stimulation is typically used to enhance sensory awareness and initiate swallowing but is not directly linked to UES duration. A chin-down posture can help protect the airway during swallowing but again does not focus on extending UES opening. Similarly, the use of thickened liquids can assist in improving swallowing safety and manage aspiration risk but does not contribute to the prolonged opening of the UES itself. Therefore, the Mendelsohn maneuver stands out as the
