SCENAR technology - frequency help please

  1. Jun 21, 2009 #1
    Hello

    I am a SCENAR therapist, and I am looking for clarification on something which has confused me for a while. The SCENAR device stimulates the body to heal itself, by transmitting short impulses (measured in microseconds), which replicate neuro-impulses, the property of the impulse is such that it is able to penetrate the C-fibres in the skin, one impulse is as follows (I have connected it to my oscilloscope):

    P1010016a.JPG

    The following shows a number of regular impulses on a set frequency 1/Y (ignore the C and D)

    P1010001aaa.JPG


    A setting on the device allows another impulse to come almost immediately after the first (represented by time X). This is called "intensity", when Int=2, it shows on the oscilloscope as follows.

    I would like to know how to describe this resultant frequency in terms of X and Y

    Thanks for you help, regards Phil

    Dear Phil,

    You'd better post your question on the RITM OKB's forum as they are the patent holders and the manufacturer of the original scenar devices.

    Here is the link for their forum http://www.scenar.com.ru/eng/index.php

    Best wishes

    Thanks, I was going to go there next, although they aren't very active. I wanted an opinion from a scientist, who had nothing to do with scenar.

    It seems a simple request, all I want is an equation, surely there must be other scientific equipment where impulses can behave in a similar manner, if so it must be describable using maths.

    Regards Phil

    Hi Phil,

    X (horisontal axis) is time in ms and Y (vertical axis) is Voltage, V

    I should not have used X and Y, any other algebraic characters would suffice.

    In my images they are both time in ms

    The "impulse" function (not really an impulse ie. dirac delta) can be described by a decaying sine wave. That is a sine wave that quickly dies off and repeats at frequency F.
    Where

    [tex]\omega[/tex] =[tex]2\pi[/tex] F

    Basically:
    [tex]Asin\omega[/tex]*e[tex]^{-t/\tau}[/tex]

    where A is the maximum amplitude of the voltage, [tex]\omega[/tex] is basically the frequency of the sine wave, and the e[tex]^{-t/\tau}[/tex] defines how fast the sine term decays.

    I'm not exactly sure how you would describe the quickly repeated next impulse. Maybe an envelope function similar to an AM radio wave?

    Just some thoughts i'm sure someone else can help a bit more.
