JD Elder:

Thanks for the helpful instructions.

You say-- Marvin Sams, a prominent EEG technologist in our field,

recently stated, " Rubbing alcohol leaves a residue on the skin and it

will cause artifact. "

For site preparation, should we just be using NuPrep and then wiping it

up with water?

Alan,

Just wipe the NuPrep up with a dry paper wipe such as Kleenex. When I was practicing, I purchased Kleenex by the case.

I heard Marvin at iSNR 2006. he uses electrocaps for Qs and for

training. In response to a question about prep he said did not use

new prep, not knowing what might be left behind to interfere with the

signal. If impedance is off he uses a small implement to abrade the

area and rechecks the impedance.

In the past I had several clients who claimed that the prep I used

was unpleasant. I went to a nearby hardware store and purchased

the finest grit sanding sponge they had. I soak it in saline

solution and rub very gently at the sites. Seems to work really well.

Similar to you, I use little strips of the plastic abrasive material

used to scrub non-stick cookware. This often come glued to a sponge but

you can find just the material itself. I keep these strips soaking in a

little jar of saline solution. This avoids the muss and fuss with

NuPrep, is very efficient, leaves no residue of extraneous material and

works just as well. I think you might find this a bit easier to use than

a sanding sponge which I believe is considerably stiffer.

Hi ,

Good article.

-

I’m in constant amazement at the lack of preparation and

attention to detail in a person’s environment for data acquisition

-

The better the site preparation/input, the better the output.

Irrespective of all the preamps, filters etc., you really wish to avoid a ‘noisy’

signal to start off with.

-

We find that instead of using a cotton ball/wool on the site

area, a small torn piece of tissue or paper toweling over the electrode helps

it sit or bed down correctly. Litterally 2-3mm larger than the electrode area

allows it to bind to the 10-20 paste.

-

I would add for anyone reading to remind the patient to have

clean hair and to not use hair product, shampoo etc. on the day of the

assessment.  (eg. Was the hair with a pH neurtral shampoo a few times the night

before) We advise the patient to drink plenty of water the day before and have

a good drink of water prior to the session. Also tell the patient not do drink

tea, coke, red bull/V, coffee or anything else with caffeine prior to sessions.

 

We do recommend to the patients to shave their head and I lead

by example, but only a few see the humor in the comment.

Regards

Gavin

i would be interested in a videa or instructions on how to measure for each placement just like they do at Larry Head Institute for EEG's at hospitals anyone have those?

Never miss a thing. Make Yahoo your homepage.

Try Introduction to EEG Electrode Placement by Moberg.

http://www.moberg.com/products.html

It is interactive...and fun way to learn...although expensive.
