Re: CES as an easy and effective cost-reducing adjunct to neurofeedback-

[Guest guest]

Hello All,

Hope I didn't kindle things too much. As to the " proprietary " waveforms, this

mindalive webpage indicates that they too use specialized, randomization,

nothing too " proprietary " it seems(I think this has been presented before):

http://www.mindalive.com/1_0/techtalkceswaveforms.htm

The Oasis, on the other-hand, utilizes randomization where the pulses are

delayed or advanced somewhat to reduce habituation.* The randomization from an

Oasis, as seen on an oscilloscope, is shown in Figure 3.

Some manufacturers promote that they use a unique, " special " waveform, which is

better than what others use. The truth is that there have been NO comparative

studies of different waveforms. Almost all CES and Micro-TENS research has used

the simplest waveform to generate, which is a square wave (on and off). Although

simple and inexpensive to generate, the down side to a square wave is that the

stimulus can really " sting, " especially when the connection isn't very good. So

people with naturally thicker and/or drier skin have more concerns than a person

with thinner, moister skin. We have found that by rounding the front end of the

pulse, so it doesn't turn on so fast*, the stinging/burning sensation is reduced

by 80% without loss of effectiveness. This increases user compliance, as most

people won't use something that hurts! Figure 2 shows an oscilloscope tracing of

our rounded waveform versus a traditional square wave.
