Background: There are also many formal assessment tools available for the assessment of swallowing. Among these, there are few published clinical dysphagia assessment tools that provide detailed assessment of swallowing. One of the tool which has been psychometrically validated and standardized for the Indian population is Manipal Manual for Swallowing Assessment (MMSA) which involves the assessment of structure, sensory and motor functions along with trial feed. This test is used in the present study to check for its efficacy in the identification of aspiration.
Method: A total of 25 individuals participated in the study. All the individuals were diagnosed to have Dysphagia based on MMSA [35]. All the 25 individuals underwent MMSA test. Individuals with suspected aspiration and no aspiration were identified by experienced speech pathologists in the field of swallowing disorders. All these individuals were subjected to videofluroscopy testings to confirm aspiration. Concurrent validity for MMSA was established through the measurement of sensitivity, specificity, positive predictive value, negative predictive value and the efficiency.
Results: Results revealed that 77% of the individuals with aspiration were actually aspirators whereas 67 % of the predicted individuals with no aspiration were actually the non aspirators and hence this test can be used to identify individuals with aspiration with overall efficiency of 72 %.
Conclusions: Results revealed a high sensitivity and specifivicity for MMSA. Thus, MMSA is proven a valuable tool in the dysphagia assessment, in particularly aspiration.
