Goniometers for Life Science Research

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. These goniometers are used conjunction with BIOPAC data acquisition and analysis systems, which normally contain electrodes, AcqKnowledge software, an MP data analysis and acquisition hardware platform, amplifiers, transducers and other system components.

The figure shows sign conventions for the most common joints:
