Gelenkmoment
Gelenkmoment, literally joint moment, is the rotational effect produced about a joint axis by the forces acting on the body segment(s) connected at the joint. In biomechanics and robotics, it is synonymous with joint torque and represents the net effort required to rotate or stabilize a joint against external loads, gravity, and muscular forces. The moment is measured in Newton-meters (Nm) and depends on the distance (moment arm) from the joint axis to the line of action of the force and on the component of the force that acts to rotate the joint.
Calculation: In a rigid-body model, the moment about a joint axis equals the sum over forces of
Interpretation: The net Gelenkmoment reflects the combined action of all muscles crossing the joint, external loads,
Applications: Gelenkmoments are used in gait analysis, sports biomechanics, rehabilitation engineering, the design of orthoses and
