Goniometers for Life Science Education

BIOPAC offers twin-axis goniometers, torsiometers, and finger goniometers to obtain accurate measurement of polycentric joints. Telescopic endblocks compensate for changes in distance between the two mounting points as the limb moves.  BIOPAC Goniometers and torsiometers are designed for the measurement of limb angular movement. Goniometers transform angular position into a proportional electrical signal. Goniometers incorporate gauge elements that measure bending strain along or around a particular axis.

Used in conjunction with the Biopac Student Lab and other components, these goniometers and torsiometers are key elements of a complete life science teaching system.

The below figures show sign conventions for the most common joints:
