What was measured

The development of the biomechanical model of the PES in order to quantify non-stationary pharyngoesophageal vibrations and drawing conclusions on the temporal characteristics of tissue stiffness, oscillating mass, pressure, and geometric distributions within the PES. The biomechanical model identify mathematical dependencies and analyse extracted time signals of the PES opening and contours (i.e. the opening and closing of the vibrating mucosa of the PES). The PES waveform allowed us to calculate the fundamental frequency (Hz).
