Thanks to everyone who replied. I did google exactly that phrase, cold pressor equipment and got some article but no "equipment" so the four I skimmed the methods sections on that I could access did not mention the actual equipment they used.
But yes, we apparently circulating the water is very important if you are doing a real study (as opposed to classroom demos) because the heat given off by the arm will warm the water around the arm and of course, you really want to immerse through above the elbow so just a bucket doesn't really work, you have to have an elongated tub. I will check out the links. Thanks, Jim. Annette Annette Kujawski Taylor, Ph. D.

I'm not sure what Annette means by "never worked right". Out of interest I looked around and found some relevant information. Following article appeared googling " 'cold pressor' methodology' and refers to commercially available "circulating water bath." Abstract raises many of the concerns mentioned by Annette. http://www.jpain.org/article/S1526-5900(04)00746-1/abstract Googling "circulating water bath" brings up lots of manufacturing hits, although perhaps size or cost might be prohibitive. Googling " 'cold pressor' equipment " brought up following article, which again mentions problems cited by Annette, as well as the fact that many studies have used home made equipment. Article itself is available at 2nd site and gives suggestions for construction of such devices. http://www.jpain.org/article/S1526-5900(05)00366-4/abstract http://pedpsych.psychology.dal.ca/pdf/JOP2005.pdf Hope this helps.

Do any of you use this task or do you know anyone who does who can direct me to the proper equipment. We have used crude equipment in the past and it never worked right. You need a pump to circulate the water so that it doesn't warm up around the arm and you need more of trough than a bucket to submerge properly. I've read some methods sections of articles that use the task but they don't describe the equipment in enough detail to know where or now to purchase it. We actually have some unused funds and the end of the fiscal year is upon us and I'd like to use it up for something that we can use in the future as well. A web search has been frustratingly nonproductive. Any pointers in the proper direction would be gratefully appreciated. Annette Annette Kujawski Taylor, Ph. D.
