Shieh WY, Wang CM, Chang CS - Sensors (Basel) (2015)

Bottom Line: All signals are received and processed for swallowing event recognition.A total of 19 volunteers participated in the testing and over 57 measurements were made.The results show that the proposed approach can effectively distinguish the swallowing function in people of different ages and genders.

ABSTRACT
Dysphagia is a condition that happens when a person cannot smoothly swallow food from the mouth to the stomach. It causes malnourishment in patients, or can even cause death due to aspiration pneumonia. Recently, more and more researchers have focused their attention on the importance of swallowing and respiration coordination, and the use of non-invasive assessment systems has become a hot research trend. In this study, we aimed to integrate the timing and pattern monitoring of respiration and swallowing by using a portable and non-invasive approach which can be applied at the bedside in hospitals or institutions, or in a home environment. In this approach, we use a force sensing resistor (FSR) to detect the motions of the thyroid cartilage in the pharyngeal phase. We also use the surface electromyography (sEMG) to detect the contraction of the submental muscle in the oral phase, and a nasal cannula to detect nasal airflow for respiration monitoring during the swallowing process. All signals are received and processed for swallowing event recognition. A total of 19 volunteers participated in the testing and over 57 measurements were made. The results show that the proposed approach can effectively distinguish the swallowing function in people of different ages and genders.

sensors-15-12428-f014: Average duration of (a) Jitter and (b) TET for the age group 31–50 years old.

Mentions: Figure 14 further shows the results of average Jitter and average TET for the 31–50 years old age group. We can find that Jitter and TET become longer as the volume of water increases. Moreover, when we increase the volume of water to 20 mL, the male participants display piecemeal swallowing situations. In this case, they need to swallow the 20 mL water in many times, therefore their Jitter and TET cannot be measured.
