A myotrophic lateral sclerosis (ALS), also known as motor neuron disease (MND), is a representative neurodegenerative disease, which results from the death of motor neurons in the brain and spinal cord and is accompanied by systemic symptoms such as upper and lower extremity muscle loss, swallowing and speech disorders, and respiratory distress. The exact cause of ALS has not been identified, and no treatment has yet been established for a full recovery. According to a domestic epidemiological study based on data from the Korean National Health Insurance Service (June et al, 2019), the annual incidence of ALS in South Korea is 1.2 per 100,000 population, and the prevalence is reported to be 3.43 per 100,000 population.According to the site of onset, ALS is classified as either spinal or bulbar onset. For spinal, symptoms begin in the upper and lower extremities and bulbar begins with a speech or swallowing disorder (Brown & Al-Chalabi, 2017). However, over time, both spinalonset and bulbar-onset ALS lead to upper and lower extremity muscle loss and swallowing disorders (van Es et al., 2017). In particular, swallowing disorder is a common symptom in patients with ALS and is a major cause of disruption for the safe intake of adequate fluids and food. ALS patients with swallowing disorders experience various negative health consequences such as increased time and effort for eating, weight loss, and dehydration (Stavroulakis et al., 2014). Weight loss and malnutrition are important factors that negatively affect disease prognosis and are also known to affect survival time. Therefore, for patients with ALS who experience a severe swallowing disorder, gastrostomy
