Positioning Aids

The active portion of the strain gauge should not touch anything
outside of the limb during testing, and the limb or digit should not
move to prevent artifact. Positioning foam blocks helps to position
the patient in a comfortable way so they will not move during testing.

All blocks are easily cleaned and can withstand years of use.



An eight piece set of contoured foam blocks used to position the legs, arms, hands and feet for plethysmography studies. The PAK8 includes two of each piece shown here.


A five piece set, similar to the PAK8, is designed for forearm plethysmography studies. It includes two of each size wedge and one U-shaped block.
