For automatic swallowing detection, RehaIngest combines a two-step procedure: The simultaneous change of resistance caused by lifting tongue base and thyroid cartilage leads to a shift in bioimpedance (step one). The second step uses EMG, which determines the activity of the suprahyoid muscle while the larynx is lifted. RehaIngest identifies the resulting changes in bioimpedance and logs it as swallow.
Markings on the result curves provide online annotations on the success of the swallowing process.
For evaluation, each swallow recorded is evaluated with consistency-specific reference values for the extent and speed of laryngeal elevation.
A 3D animation replay makes the course of the swallow visible.
Measurement results can be compared, displayed and exported.
