Which intervention strategy is most likely to effectively help a patient with a limited duration of upper esophageal sphincter opening?

Using submental surface electromyography (sEMG) as biofeedback is an effective intervention strategy for patients with limited duration of upper esophageal sphincter opening. This strategy involves the use of surface electrodes placed under the chin to monitor muscle activity associated with swallowing. It provides real-time feedback to the patient about their muscle function, thereby helping them to adjust and improve their swallowing technique.

The biofeedback aspect is critical because it allows the patient to become aware of specific muscular movements and contractions needed for effective swallowing. This awareness can lead to better control and coordination of the muscles involved in opening the upper esophageal sphincter, potentially increasing the duration of opening during swallowing. The intervention also promotes self-awareness of muscular tension and relaxation, which is essential for effective swallowing.

In contrast, the other options focus on assessment or observation rather than intervention. Completing a fiberoptic endoscopic evaluation is primarily a diagnostic tool to assess the swallowing mechanism and may not directly provide therapeutic support. Performing cervical auscultation involves listening to sounds produced during swallowing, which can offer insights but does not actively help the patient improve muscle function. Teaching the patient to use palpation and a mirror might enhance awareness of throat movements, but it does not provide direct biofeedback to strengthen or
