In an open kinematic chain, to optimally function distally, multijoint agonists rely on their antagonists to provide stabilization at proximal joints.

Question

Quizplus · Accepted Answer

In an open kinematic chain, the movement at a distal joint is not constrained by the movement of other joints. Therefore, multijoint agonists rely on their antagonists (muscles that have opposite actions) to provide stabilizing force at the proximal joint during the movement to ensure optimal function.
