Active- Passive Muscle Insufficiency
The limited ability of a two joint muscle to produce force (active maximal measurable tension) when joint position places the muscle on a stretch or it has maximally shortened at its end range.
Example of active insufficiency
Hip flexion with knee extension: rectus is actively over shortened and hamstrings are passively stretched.
Example of active insufficiency
Hip extension with knee flexion: hamstrings are actively over shortened and rectus is passively stretched.
What is passive insufficiency?
Biarticular antagonist maximal elongation prohibits agonist from further active movement.
Examples of passive insufficiency
rectus femoris tension
hamstring tension
