Long-Term Outcomes of Dysphagia Rehabilitation With an Adjustable Resistance Training Device in Laryngectomized Individuals

BackgroundThis study investigated long-term outcomes of dysphagia rehabilitation with an adjustable resistance training device (Swallowing Exercise Aid, SEA2.0) in laryngectomized individuals.MethodsSeventeen laryngectomized participants who participated in a Clinical Phase II Trial were reevaluated at T3 (approximately 6 months after T2), including an interview, PROMS, oral intake, and swallowing capacity. Results of T3 were compared with the earlier time points T0 (baseline), T1 (after 6 weeks of training), and T2 (after 8 weeks of rest).ResultsAll outcomes at T3 remained improved compared to T0. Compared to findings at T2, participants reported some deterioration in swallowing at T3. Swallowing capacity and oral intake slightly decreased. Swallowing-related quality of life slightly improved.ConclusionsBenefits of swallowing rehabilitation with the SEA2.0 in laryngectomized individuals are still noticeable long term. The need for continued exercising to fully maintain improved function is likely, but the required intensity and extent should be determined in further research.
