In fast moving ergometers for human limbs the acceleration induces tra
nsient moments due to the inertia of the limb, in combination with a n
ot perfectly rigid limb fixation. Methods are described by which these
effects can be corrected for. The correction of the moment consists o
f filtering the recorded moment and angular acceleration, and then add
ing both signals. Inertial transients can thus be reduced to 1/6 or le
ss. The recorded angle can be corrected for the compliance of the limb
fixation. (C) 1997 Elsevier Science Ltd.
