• The adduction angular impulse is a complimentary measure of knee joint loading and accounts for both the load as well as the loading time. If a person walks more slowly, the peak adduction moment may be lower but the adduction impulse may be higher as the loading time will be longer. • The DonJoy OA Adjuster ™ reduces the adduction impulse up to 37% 35 . • The more the hinge is dialed in, the greater the reduction of the knee adduction impulse 35 .
