Effects of Proprioceptive Neuromuscular Facilitation on Swallowing Function of the Stroke Patients

The purpose of this study was to investigate the effects of Proprioceptive Neuromuscular Facilitation (PNF) on the swallowing function of stroke patients. Twelve-week PNF (facial, tongue, and breathing exercise) was applied in the experimental group consisting of 12 subjects, and a general swallowing exercise program was applied to the control group consisting of 12 subjects. In addition, the signs of improvement in the stroke patients (N=24) swallowing function were examined by conducting a video fluoroscopic swallowing study. The data were analyzed using the SPSS ver. 21.0 program, which was also utilized to gain statistical information (percentage, mean, and standard deviation), and paired t-test was conducted. As a result of the analyses, the following conclusions were arrived at. The 12-week PNF significantly improved the functional dysphagia scale, penetration-aspiration scale, pharyngeal transit time, swallowing response time, residue in valleculae, and residue in pyriform sinuses enhanced swallowing functions of the stroke patients (p<.05). In conclusion, the PNF intervention in the swallowing function of the stroke patients was found to be an effective exercise program.
