Nerve Express is an automatic computer based
system that provides a Quantitative Assessment of the state of the
Autonomic Nervous System (ANS). Before the development of Nerve Express
Autonomic Tone (the overall, qualitative state of the ANS) could be
assessed only approximately and formulated by three qualitative gradients:
Traditionally the criteria used for
evaluating these three gradients were clinical and laboratory findings
Assessment of the Autonomic Tone was thus labour intensive and not always
feasible.
Nerve-Express solves this problem through a
new approach to the recognition and classification of the states of the
ANS - analysis of Heart Rate Variability (HRV). In addition, Nerve-Express's
expanded and reproducible capacity of HRV analysis allows for precise
recognition and classification of forty-nine states of the ANS with a
corresponding qualitative description for each one
Nerve-Express uses technology that has been
extensively researched for over twenty years. However, until the
development of the Nerve-Express system, there was no practical way to use
this technology outside of a research laboratory, due to the fact that
automatic reproducibility proved impossible using any other existing HRV
analysis system today.
Nerve-Express provides not only a
mathematical interpretation of HRV spectral analysis, but also performs a
qualitative analysis of the resultant parameters based on principles of
artificial intelligence
The algorithms used in Nerve-Express were
developed in 1987. and were researched and tested on over fourteen
thousand patients. The Nerve-Express test, called the Orthostatic Test, is
a simple procedure that takes only a few minutes to administer and allows
ANS assessment using a very easy, acceptable, and predicable means of
the ANS provocation .
