Abstract Background Sarcopenic dysphagia is characterized by difficulty swallowing due to loss of whole‐body skeletal and muscle mass function. Despite multiple reports regarding sarcopenic dysphagia, no verified diagnostic methods exist. The purpose this study was develop a algorithm for verify its reliability validity. Methods First, our research group, the Working Group on Dysphagia, developed dysphagia. Patients 65 years older who could follow commands were eligible assessment using algorithm. without sarcopenia, with normal function, disease that an obvious cause their considered not have Then, strength assessed tongue pressure. Those poor deemed be at probable risk those possible Second, we applied inpatients investigated characteristics, mass, strength, motor nutritional status. We analyzing intra‐ inter‐class correlation coefficients kappa statistics. Third, validity difference in proportion patients between malnutrition groups factors logistic regression analysis. Results A total 119 participated study. Their mean age 86.1 years, 55 (46%) men. Among patients, 32 categorized as having 18 69 intra‐class coefficient 0.87 (95% confidence interval [CI]: 0.73‐1.01), 0.98 CI: 0.92‐1.02), indicating high inter‐rater reliabilities. In investigation algorithm's validity, 67 analyzed. significantly higher than group (P = 0.028). Malnutrition independently associated 0.013 0.003, respectively). Conclusions developed, verified. All sarcopenia or should which requires treatment involving only rehabilitation but also improvement.
