Standardized Dysphagia Diet in Clinical Evaluation of Swallowing Function

Recruiting

Conditions: Dysphagia, Swallowing Function, Diet Modification, Dysphagia Diet, Diet Standardization

Brief Summary: Diet modification has been a vital component in the management of dysphagia. The lingual manipulation of bolus, pharyngeal propulsion, and initiation of swallowing reflex are all affected by the texture of bolus. However, there is a limited literature and consensus regarding how to apply different food consistency in the swallowing function evaluation of dysphagic patients. Recently, International Dysphagia Diet Standardization Initiative (IDDSI) has provided a universal standard of food consistency. The present study aims to evaluate the accuracy of clinical swallowing evaluation using IDDSI standardized food in dysphagic patients, in an attempt to establish protocols of clinical evaluation and diet selection in dysphagic patients.
