Outline of Final Research Achievements

This study aimed to elucidate the usefulness of latency using piezoelectric film for non-invasive dysphagia screening, and to clarify the issues of evaluation of and rehabilitation for dysphagic patients at hospitals in Niigata prefecture. Forty-one healthy subjects were analyzed. Motion analysis of the hyoid bone using videofluorography (VF), and the waveform analysis of the front neck using piezoelectric films were simultaneously performed. Latencies of the three hyoid bone movement were significantly correlated with the ones of three phases of the piezoelectric waveform. Swallowing evaluation using piezoelectric film may be a valuable method for dysphagia screening. Also, evaluation of and rehabilitation for dysphagic patients are conducted in about 70% of the hospitals in Niigata prefecture.
