MBSS

The MBSS test allows the swallow to be viewed in real time and all phases of the swallow be evaluated on various consistencies.

Signs of Dysphagia are exhibited by 68% of nursing home residents (Steel, Greenwood, Ens, Robertson, and Seidman-Carlson, 1997). A clinical swallowing evaluation (i.e. bedside swallowing exam) can help determine the presence of Dysphagia. However, only symptoms of pharyngeal (throat) and esophageal (esophagus) Dysphagia can be identified clinically, while Dysphagia in the stages of oral, pharyngeal, and esophageal cannot be officially diagnosed at bedside.

Research has shown that even the most experienced clinician/Speech Pathologist will fail to identify approximately 40% of the patients who aspirate during a bedside swallow examination (Logemann, 1983). Continuous aspiration of food or liquid is likely to cause aspiration pneumonia, which affects 44% of the residents in long term care (Langmore et al, 1998).

A full evaluation of the swallow function is easily accessed by the A-P (anterior posterior) view in addition to the lateral (side) view. The A-P view is not usually completed in the hospital setting due to positioning restrictions. The use of a specialized fluoroscopic system designed for the mobile MBSS exposes the patient to less radiation than what typically is found in a hospital setting. Approximately 1 Rad per minute is used during fluoroscopy on the mobile unit, compared to 2-3 Rad per minute in the hospital environment.
