NCT05221801

Brief Summary

Most caregivers do not know the influence of improper positioning therefore subjects suffer from possible choking risks. The aims of this study were to investigate the timing and coordination of swallowing and respiration in 4 different seat inclination angles, with liquid and bolus. A self-developed wearable device to measure the submandibular muscle surface EMG, the movement of thyroid cartilage and respiratory status of nasal cavity. This program could auto-analysis the onset and offset of duration, and the excursion and strength of thyroid cartilage will be calculated when it was moving, coordination between breathing and swallowing was also included. The results of this study would serve as the clinical guidelines for proper feeding positions for different populations and for different food contents.

Outcome Measures

Primary Outcomes (3)

  • Electromyography

    Two electrodes were attached to the submandibular muscle to register the electric potential generated by the muscles.

    5 seconds before the beginning of the swallow to 5 seconds after the end of the swallow.

  • thyroid cartilage excursion

    A force-sensing resistor (FSR) was fixed over the larynx at the thyroid cartilage position with an elastic belt to detect the cartilage excursion.

    5 seconds before the beginning of the swallow to 5 seconds after the end of the swallow.

  • nasal airflow

    A nasal airflow cannula was placed in front of the nasal cavity and was connected to a pressure transducer (Pro-Tech Services, Murrysville, PA, USA) to detect exhalation and inhalation.

    5 seconds before the beginning of the swallow to 5 seconds after the end of the swallow.
