Nerve -Express is a fully automatic, non- invasive; computer based system designed for quantitative assessment of the Autonomic Nervous System (ANS) based on Heart Rate Variability analysis. It is the first and only system available today for any type of practitioners or researchers.
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:
Autonomic Balance (Vegetative Homeostasis)
Sympathetic Prevalence
Parasympathetic Prevalence.
Traditionally, the criteria used for evaluating these three gradients were clinical and laboratory findings. Assessment of the Autonomic Tone was thus labor intensive and not always feasible.
Nerve-Express solves this problem through a new approach based on the Theory of artificial intelligence. The Nerve - Express system objectively and reproducibly evaluates the state of the ANS during rest (up to 24 hours) as well as during orhtostatic test. In addition, Nerve-Express' s expanded and reproducible capacity of HRV analysis allows for precise recognition and classification of 74 states of the ANS with a corresponding qualitative description for each one.
The algorithms that are used by Nerve-Express were developed and tested for over twenty years and involved more than twenty thousand patients. 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 Orthostatic Test providing by Nerve-Express, is a simple procedure that takes only a several minutes to administer and allows ANS assessment using a very easy, acceptable, and predictable means of the ANS provocation.
