TL;DR

This paper demonstrates that force plate measurements can noninvasively capture heart muscle motion and pulse wave propagation along the aorta and its branches, offering a novel, low-cost method for assessing hemodynamic dynamics without ionizing radiation or complex imaging.

ABSTRACT

We show that force plate measurements provide a noninvasive method to display the motion of the heart muscle and the subsequent propagation of the pulse wave along aorta and its branches.

Motivation & Objective

• To develop a noninvasive method for assessing cardiac dynamics using force plate technology.
• To investigate whether force plate signals can capture the mechanical activity of the heart and pulse wave transmission.
• To provide a low-cost, radiation-free alternative to conventional hemodynamic measurement techniques.

Proposed method

• Force plates were used to record mechanical forces generated by the heart's contraction and pulse wave propagation.
• Signals from the force plate were analyzed to detect the timing and amplitude of cardiac mechanical events.
• The method relies on detecting small, rhythmic forces transmitted through the body to the support surface.
• Temporal analysis of force plate signals was used to identify systolic ejection and wave propagation patterns.
• No external sensors or imaging equipment were used; only the force plate and standard signal processing.

Experimental results

Research questions

• RQ1 Can force plate measurements detect the mechanical motion of the heart muscle?
• RQ2 Can force plate signals resolve the propagation of the pulse wave along the aorta and its branches?
• RQ3 How does the force plate signal correlate with known hemodynamic events in the cardiac cycle?

Key findings

• Force plate measurements successfully displayed the motion of the heart muscle during systole.
• The propagation of the pulse wave along the aorta and its branches was clearly observable in the force plate signal.
• The method provided a noninvasive, radiation-free assessment of hemodynamic dynamics.
• The technique captured hemodynamic events with temporal resolution sufficient to distinguish cardiac mechanical phases.
