Active insufficiency deals with making a muscle shorter so you can strengthen the other muscles around it.

Below are examples of active insufficiency...

The shortening of the rectus femoris limits full hip flexion when the knee is fully extended.
Maximal shoulder flexion cannot be achieved simultaneously with maximal elbow flexion due to the shortening of the biceps brachii.
Maximal knee flexion and maximal plantar flexion are limited due to the shortening of the gastrocnemius.
Full knee flexion and full hip extension cannot be achieved simultaneously due to the shortening of the hamstring muscles.

When the opposing muscle (antagonist) is stretched to a point where it can no longer lengthen and allow further movement, passive insufficiency is reached. Another way to think about it... the inability of a 2 joint muscle to maximally lengthen on 1 joint if it has already lengthened on the other joint.

Passive insufficiency tells us how to maximize the stretch for a muscle. Passive insufficiency can affect your goniometer ROM values if not paid attention to. For example, when the hamstring muscles are lengthened, it will affect the knee joint ROM for extension. It is important to know this so you can rule out any joint/musculoskeletal issues.

Below are examples of passive insufficiency...

Full finger flexion cannot be achieved if wrist flexion occurs simultaneously.
Maximal hip flexion and maximal knee extension are limited by the lengthening of the hamstring muscles. If the hip joint is flexed, maximal knee extension will be compromised or insufficient due to lengthening of the hamstring muscles. Vice versa...if the hamstring muscles are first elongated at the knee joint, the hamstring muscles will become passive insufficient at the hip joint resulting in reduced hip flexion ROM.
Full knee flexion is limited by the stretching of the rectus femoris if the hip is fully extended.

1. With this being known, what is the clinical relevance of this?

2. How can this be applied when working with athletes and their athletic performance?

3. How can this be applied when working with patients in a rehab setting? Provide examples.
