BACKGROUND: Dysphagia is a common problem in acute stroke patient. Aspiration pneumonia increases in this group. Swallowing therapy is immediately conducted in a stable stroke patient. An effectiveness of our program has not been determined. OBJECTIVE: To determine an effectiveness of conventional swallowing therapy in acute stroke patients with dysphagia. METHODS: We retrospectively reviewed data from medical records of acute stroke patients with dysphagia who participated a swallowing therapy from January 2017 to June 2017. Fifty-seven acute stroke patients with dysphagia (26 males and 31 females) were participating in a conventional swallowing therapy (50 minutes a day for 3 days per week). A functional oral intake scale (FOIS) and swallow function scoring system (SFSS) were used to determine an effectiveness of the swallowing therapy. FOIS and SFSS scores before the first therapy session and after the last therapy session were compared using a paired -test. RESULTS: The mean age of the patient was 69.5 ± 15.35 years. The period from stroke onset to the first swallowing therapy session was 7.5 ± 6.69 days. The number of therapy was 5.6 ± 2.83 sessions. Participants showed a significant improvement of the FOIS (mean score increased from 1.74 to 3.30 points, = 0.001) and SFSS (mean score increased from 2.51 to 3.68 points, = 0.001). Forty-two percent of patients with tube dependent change to total oral intake. CONCLUSION: Conventional swallowing therapy is an effective treatment in acute stroke with dysphagia.
