In contrast to such limitations, isokinetic testing provides feedback on all of the above factors. That is, isokinetic testing provides force output values (torques) for every point throughout the movement, and it also allows for control of the velocity of such movements. This involves the use of special equipment that continuously measures and records torques and joint angles as a body segment moves through a range of motion at a preselected velocity controlled by the isokinetic dynamometer (see photo 22.1).
