Background: Among the causes of dysphagia in individuals with severe motor and intellectual disability (SMID), addressing disuse atrophy of swallowing-related muscles are expected to improve patient outcomes. Disuse atrophy is associated with a reduced frequency of muscle activity, and swallowing frequency may be associated with the atrophy of swallowing-related muscles. Objective: We aimed to investigate the relationship between swallowing frequency and swallowing-related muscle mass in individuals with SMID. Methods: This cross-sectional study included 62 individuals with SMID (31 men and 31 women; mean age: 46.9 [standard deviation, 13.2] years) admitted to our center. Swallowing frequency was measured using a laryngeal microphone, and swallowing-related muscle mass was estimated by measuring the cross-sectional area of the geniohyoid muscle (GHM) using an ultrasonic diagnostic device. Results: Increased swallowing frequency and body weight corresponded to a larger cross-sectional area of the GHM. Moreover, women had a smaller GHM cross-sectional area than men. Multiple regression analysis showed that the swallowing frequency, body weight, and sex were significantly and independently associated with the GHM cross-sectional area (p < 0.01). Conclusions: Swallowing frequency and body weight significantly affect swallowing-related muscle mass in individuals with SMID.
