Question: In adult patients with dysphagia, how does Respiratory Muscle Strength Training compare to the Shaker exercise in improving functional outcomes of swallowing? Oropharyngeal dysphagia is a dysfunction of swallowing which can affect the ability of a bolus to move from the oral cavity through and into the esophagus. This is a common issue among individuals with neurologic conditions as well as elderly adults and can cause complications such as aspiration pneumonia, malnutrition, dehydration, and possibly death. This systematic review explores two leading therapy exercises that are being used to improve the symptoms of oropharyngeal dysphagia: Respiratory Muscle Strength Training (RMST) and the Shaker Exercise (also commonly referred to as head lift). RMST is an exercise technique that targets the inspiratory and expiratory muscles to increase the amount of air pressure an individual can generate. The Shaker Exercise focuses on strengthening the suprahyoid and infrahyoid muscles to promote upper esophageal sphincter (UES) opening.
