Pressure Gage

Is there any REAL evidence that wrist blood pressure gages are less accurate than other "home use" gages?

Doctors seem to universally claim that wrist measuring devices give erratic readings and so are less accurate than arm wrapped devices. If this is a real problem, isn't it likely it Is the result of the requirement for readings to be taken at the same level as ones heart, which is automatically achieved with arm mounted devices but up to each individual's judgment with wrist devices? Or is there some technological reason the wrist devices are inherently less accurate?

Its mostly a biological reason - the veins in the wrist are a smaller diameter than the elbow, and the wrist is bonier. This causes two problems: the veins are not large enough on all people to have much effect on the blood pressure gage, and pressure cuffs don't always fit correctly on people with bony wrists.
