Do they use a blood pressure cuff?

[Nick-P]

Hey everyone, I posted here awhile back about being physically disabled but having to take a polygraph (and if it could affect the results). So far I've not had to take one, but one is coming up this Friday.

This leads me to my question..

Because of my disability, which is brittle bones, I cannot in any way use a blood pressure cuff, as the squeezing of the cuff can literally break my bones (and they don't fit anyway). If one must be used, I simply cannot do it.

So does anyone know if Polygraph Examiners use a blood pressure cuff, and if they must be used to "accurately" administer a poly?

Thanks!

It's standard procedure to use a blood pressure cuff. In some situations, polygraph operators may place the cuff on the subject's leg instead of the arm. And alternatively, some polygraph operators may use a finger cuff, such as this one marketed by the Lafayette Instrument Company:

I recently tested an individual who had a well-documented case of Osteogenesis Imperfecta, or Lobstein's Syndrome, commonly referred to as "Brittle Bones Syndrome".  Using the right size BP cuff (there are at least four different sizes) on the leg, the individual was tested without pain or discomfort.
