[Purpose] This study examined the effects of neck exercises using PNF on the swallowing function of stroke patients with dysphasia. [Subjects and Methods] A total of 26 study subjects were selected and randomly divided into an experimental group of 13 subjects, who received the PNF-based short neck flexion exercises, and a control group of 13 subjects, who received the Shaker exercise. [Results] The experimental group showed statistically significant improvements in premature bolus loss, residue in the valleculae, laryngeal elevation, epiglottic closure, residue in the pyriform sinuses, and coating of the pharyngeal wall after swallowing, and improvements in pharyngeal transit time, and aspiration on both the new VFSS scale and the ASHA NOMS scale. [Conclusion] PNF-based short neck flexion exercises appear to be effective at improving swallowing function of stroke patients with dysphagia.
