Correcting for limb inertia and compliance in fast ergometers

In fast moving ergometers for human limbs the acceleration induces transient moments due to the incrtia of the limb, in combination with a not perfectly rigid limb fixation. Methods are described by which these effects can be corrected for. The correction of the moment consists of filtering the recorded moment and angular acceleration, and then adding both signals. Inertial transients can thus be reduced to 1/6 or less. The recorded angle can be corrected for the compliance of the limb fixation.
