Effect of Chin Tuck against Resistance Exercise in Citizens with Oropharyngeal Dysphagia—A Randomised Controlled Study

Abstract

Oropharyngeal dysphagia (OD) impacts the safety and efficacy of the swallowing function. The aim was to uncover the effect of chin tuck against resistance (CTAR) exercises compared to standard care in relation to the swallowing function in citizens with OD. Ninety-two citizens (46% male, median age 78 years (IQR 71, 84)) with OD confirmed by the Volume-Viscosity Swallow Test and/or Minimal Eating Observation Form version II were randomised to standard care with the addition of CTAR daily for six weeks or standard care only. The participants were included from seven Danish municipalities from March 2019 to October 2020. A nonsignificant effect on dysphagia of CTAR training combined with standard care versus standard care alone was documented. Both CTAR training combined with standard care and standard care alone had a significant effect on the swallowing function in citizens with OD, with the best effect in the group receiving CTAR training combined with standard care. A significant effect compared to baseline was observed in all participants (p = 0.03) after 12 weeks. Participants in both groups had a significant reduction in problems with manipulating food in the mouth (p = 0.005), swallowing (p = 0.005), and chewing (p = 0.03) but an increased appetite (p = 0.01). The reported quality of life scored with DHI-DK was significantly improved in both groups.
