Purpose: To develop a clinical evaluation which can access systematically in screening, diagnosis and treatment of swallowing disorders by evaluating the cause and severity of swallowing disorder systematically on stroke patients with risk of dysphagia.
Materials and Methods: The initial test is composed of the total of 23 initial items designed to assess the function of swallowing organs. Scoring system of 23 initial items was based on the standard deviation and the mean of the results of 46 normal adults. Thirty stroke patients showing signs of dysphagia were assesed by initial items, and then aspiration presence were mesured by videofluoroscopic swallowing study(VFSS). Odds ratio between each initial items and VFSS results were calculated in order to evaluate the relative effect.
Result: The test involved the following 18 items which odd ratio were more than 1.0; Orientation, 3 step obey command, function of cough, respiration number of repititions, respiration strength, number of repetition (/p?/), drooling saliva, number of repetition (/t?/), number of repetition (/k?/), tongue sensation, inter-incisor distance, movement of soft palate, oral sound, hoarseness, control of vocal cord strength, aspiration with fluid, excursion of thyroid cartilage, latency of thyroid cartilage elevation. Among 23 initial items, we selected final 18 items and developed a dysphagia test that total score was 100 points considering the relative proportion of the odd ratio of each item.
Conclusion: The dysphagia test could be used to evaluate the swallowing disorder systematically and quantitatively in stroke patients.
