摘要

It is important to identify and managing dysphagia as early as possible is very critical among stroke patients. The need for early identification and early intervention regarding aspiration. Performing instrumental swallowing evaluations is time-consuming and expensive. Therefore, there is a need for a validated clinical tool that is capable of determining aspiration and for guiding the selection of treatment strategies at acute care setting. Swallow Screen Protocol was validated with the administration of the test in 90 normal individuals (Group A) and Bedside evaluation for 30 subjects with stroke who was diagnosed as Dysphagia (Group B). Participants who were identified to have Dysphagia using SSP were also subjected to Nair Hospital Swallowing Ability Scale, the rating scale from 0 to 6 (0—Normal and 6—Complete dysphagia). Descriptive statistics was done and the mean, median and the Standard Deviation values were calculated. The Receiver Operating Characteristics curve analysis was done to find the Sensitivity (89%), Specificity (78%) and cut-off scores (26). Pearson moment correlation was used to find the reliability of the test re-test and the Inter-rater. It was found that there was a high significance (p = 0.0005) for the Test Re-test reliability(r = 0.992). The Inter-rater reliability was done by 2 independent therapists. This improved the reliability (r = 0.999) and the validity of the tool. Swallow Screen Protocol has shown a high sensitivity 84%.This study indicated that the Swallow Screen Protocol is highly sensitive and can be effectively used to screen the symptoms of swallowing difficulty in individuals with Stroke.
