Rehabilitation Practice and Science

”The study aimed to depict the influence of bolus temperature, volume, and viscosity in swallowing function by a self-designed phagometer. Two micro switches were used to detect submental muscle activity and pharyngeal motion. They were anchored on a posterior-type cervicothoracic orthosis with multiple adjustable joints to ensure the well contact between the switch and the skin. The signals detected by micro switches were amplified and recorded. The duration between two waves was defined as swallowing trigger time and used to represent the swallowing function.Ten normal male subjects without clinical evidence of dysphagia were enrolled in this study. The average age …
