Effect of chin tuck against resistance exercise on patients with dysphagia following stroke: A randomized pilot study

Abstract

Background: Recently, chin tuck against resistance exercise (CTAR) has been reported as a remedial treatment for pharyngeal dysphagia. However, the clinical evidence of the effect is still lacking.

Objective: This study investigated the effect of CTAR on the swallowing function in patients with dysphagia following subacute stroke.

Methods: The patients were randomly assigned to an experimental (n = 11) or a control group (n = 11). The experimental group performed CTAR using the CTAR device. The control group received only conventional dysphagia treatment. Both groups received training on five days a week, for four weeks. The swallowing function was measured using functional dysphagia scale (FDS) and penetration-aspiration scale (PAS), based on a videofluoroscopic swallowing study (VFSS).

Results: The experimental group showed more improvements in the oral cavity, laryngeal elevation/epiglottic closure, residue in valleculae, and residue in pyriform sinuses of FDS and PAS compared to the control group (p < 0.05, all).

Conclusions: This study demonstrated that CTAR is effective in improving the pharyngeal swallowing function in patients with dysphagia after stroke. Therefore, we recommend CTAR as a new remedial training alternative to HLE.
