Turkish Eating Assessment Tool-10 is a survey consisting of 10 questions with a Likert scale between 0 and 4 (0 = no problem, 4 = severe problem). The total score is calculated out of 40 points by finding the sum of the answers given by individuals to each question. A score of 3 or more in the survey is considered abnormal. A score of 16 or above is considered a suspicion of aspiration. Turkish validity and reliability were tested by authors in 2016.

Yale Swallow Protocol is a reliable screening test performed under expert supervision to determine the risk of aspiration at an early stage. The protocol has three main components. These are exclusion criteria, a short cognitive test, and oral mechanism, and drinking 3 oz (90 cc) water directly from the glass or with a straw. Risk factors are examined in the 1st and 2nd stages to determine the patients to whom the test can be applied. Patients who complete step 1 and are not contraindicated for testing proceed to the short cognitive testing phase. Patients who pass the short cognitive test and oral mechanism stages can proceed to the third stage, which is drinking 90 cc of water. The 90 cc water swallow challenge protocol is a simple assessment that can be used by many qualified healthcare professionals to identify aspiration risk because it is easy to perform, highly reliable, cost-effective, and clinically validated.Patients showing these findings are recorded as 'failing' the test.

In our study, the Test of Mastication and Swallowing Solids (TOMASS) will be used. The test evaluates how many bites the individual takes to eat a biscuit while sitting upright, how many chewing cycles he makes, how many times he swallows it, and how long the total time is from biting to swallowing. Video recording will be taken during the test. The number of bites, number of chewing cycles, number of swallows and total time will be calculated on the video. Individuals will be asked to eat the biscuit normally while sitting on a chair in an upright position with the throat visible. Meanwhile, video recording will be taken from the individuals' front view, showing their mouth and neck. The evaluation of the test will then be made by the evaluator. Videos will be stored in folders on an encrypted computer and only the work team will have access.
