The posture of the subjects participating in the study was evaluated with the New York Posture Assessment Method (NYPDY). In this evaluation system, postural changes that may occur in 13 different parts of the body were monitored and scored. Accordingly, five (5) points were given if the person's posture was correct, three (3) points if moderately impaired, and one (1) point if severely impaired. The total score obtained as a result of the test is a maximum of 65 and a minimum of 13. Standard evaluation criteria developed for this test were defined as "very good" if the total score is >=45, "good" if the score is 40-44, "moderate" if the score is 30-39, "fair" if the score is 20-29, and "poor" if the score is <=19
