| Outline of Final Research Achievements |
This study aimed to elucidate the relationship between the piezoelectric waveform latency, hyoid bone movement and the pharyngeal transit time (PTT) during swallowing, and evaluate the applicability of piezoelectric film for non-invasive dysphagia screening. Forty-one healthy subjects were divided into three age groups, younger (n=8), middle-aged (n=9), and older (n=24). Motion analysis of the hyoid bone using videofluorography (VF), waveform analysis of the front neck using piezoelectric films were performed simultaneously. Latencies of the three movement phases were defined as upward (VFS1), forward (VFS2), and returning to starting position (VFS3). The three phases of the piezoelectric waveform were defined as PS1, PS2, and PS3, respectively. VFS1-3 and PS1-3 were significantly correlated. Swallowing evaluation using piezoelectric film may be a valuable method for dysphagia screening.
