Functional Dysphagia Scale of Han et al After Stroke

Description

Han et al used videofluoroscopy to evaluate a patient for dysphagia after a recent stroke. This can help to identify a patient at increased risk for aspiration. The authors are from Seoul National University in South Korea.

Patient selection: status post stroke

Evaluation: videofluoroscopy

Parameters:

(1) lip closure

(2) bolus formation

(3) mastication

(4) apraxia

(5) tongue to palate contact

(6) premature bolus loss

(7) oral transit time in second

(8) triggering of pharyngeal swallow

(9) vallecular residue

(10) laryngeal elevation

(11) pyriform sinus residue

(12) coating of the pharyngeal wall

(13) pharyngeal transit time in seconds

(14) aspiration

total score =

= SUM(points for all of the parameters)

Interpretation:

• minimum score: 0

• maximum score: 100

• The higher the score the greater the risk of aspiration.

Performance:

• The scale had a sensitivity of 0.78 and specificity of 0.78 for subglottic aspiration.
