Both active and passive insufficiency are functional states that occur in multi-joint muscles only. Active insufficiency occurs when a multi-joint muscleshortens over BOTH joints simultaneously, and hence, creates so much slack, that muscle tension is almost completely lost.
What type of muscle is affected by passive insufficiency?
Passive insufficiency occurs when the multi-joint muscle is lengthened to its fullest extent at both joints, but also preventing the full ROM of each joint it crosses. Also asked, what type of muscle is affected by active insufficiency? A muscle of the quadriceps, known as the rectus femoris, enters active insufficiency in this position.
What is active insufficiency?
Active Insufficiency Explained. Active insufficiency occurs when a multi-joint muscle shortens over BOTH joints simultaneously, and hence, creates so much slack, that muscle tension is almost completely lost. Knee is flexed, hip is extended, hamstring is shortened and in a weakened position.
What is active insufficiency 2 joint muscle?
Active insufficiency 2 joint muscles cannot exert enough tension to shorten enough to allow full ROM in both joints at the same time. (For example, the finger flexes cannot produce a tight fist when the wrist is fully flexed, as they can when it is in neutral position.
What is an example of passive insufficiency?
An example of passive insufficiency would be short hamstrings, which results in the inability of the muscle to normally elongate to the degree that proper combined hip flexion and knee extension can occur, which is required for all sports.
What is passive insufficiency?
Can passive insufficiency cause injury?
What is an example of active insufficiency?
Active insufficiency is the inability of a muscle, which spans two or more joints, to create enough tension because it is already shortened. An example is if you flex your wrist and try to make a fist, versus making that fist without flexing the wrist at all.
How can you determine if active insufficiency or passive insufficiency limits the range of motion?

And at the same time during this movement active insufficiency is happening with myMoreAnd my fingers. And at the same time during this movement active insufficiency is happening with my wrist flexors because they cannot further shorten beyond what the sarcomeres.
What is passive insufficiency of the triceps?
- triceps brachii during shoulder extension and elbow extension. - gastrocnemius during ankle extension and knee flexion. Passive insufficiency occurs when the muscle cannot be stretched enough to permit full range of motion at both joints at the same time.
What is passive insufficiency of the gastrocnemius?
Passive muscular insufficiency of the gastrocnemius muscle acts on a pathologic foot, which is poorly prepared to accept the forces from the gastrocnemius-soleus complex. In this manner, a normal gastrocnemius muscle exerts abnormal forces across the foot.
What is active insufficiency vs passive insufficiency?
Both active and passive insufficiency are functional states that occur in multi-joint muscles only. Active insufficiency occurs when a multi-joint muscle shortens over BOTH joints simultaneously, and hence, creates so much slack, that muscle tension is almost completely lost.
What is passive insufficiency example?
Passive Insufficiency: Hamstrings are pulled taut into lengthened position as hips are fully flexed and knees fully extended.May 14, 2019
Is Tenodesis active or passive insufficiency?
TENODESIS: A. Passive insufficiency of finger extensors occurs when the wrist is flexed, causing the fingers to extend.
Why is passive ROM greater than active?
When the difference between the two ROMs is large, it is most likely the Passive is greater than the Active. Mechanically the limb can be moved to a certain degree but the nervous system can't support the range on its own. This is when someone has good flexibility, but poor mobility.Apr 11, 2019
What is passive range of motion?
Passive Range of Motion (PROM). This is the space in which a part of your body can move when someone or something is creating the movement, such as a massage or physical therapist. You're not the one engaging the muscles you would normally use to start the movement and do the work.Oct 25, 2021
Which position of the hip would produce active insufficiency of the hamstrings?
Active insufficiency of hamstrings - you can do hip extension or knee flexion in prone but not both simultaneously. If you flex your knee while your hip is extended in prone you cannot complete the full knee range. However when you grab your ankles and pull the knee into more flexion you'll be able to do it.
How do you make the hamstrings actively insufficient?

What is active insufficiency?
Active Insufficiency Of Muscle. Active insufficiency occurs when a multi-joint muscle reaches a length (shortened) where it can no longer apply an effective force. To demonstrate active insufficiency one can fully flex (bend) the knee on one leg while simultaneously trying to bring that leg back to achieve full hip extension.
What are some examples of passive insufficiency?
An example of passive insufficiency would be short hamstrings, which results in the inability of the muscle to normally elongate to the degree that proper combined hip flexion and knee extension can occur, which is required for all sports.
Which muscle is responsible for flexing the ankle and crossing over the knee joint?
The gastrocnemius of the calf plantar flexes the ankle but also crosses over the knee joint. Therefore, if the knee is bent, or flexed, shortening the muscle at that joint, it can no longer apply as effective a force in plantarflexion.
Can a single joint muscle produce more than one joint?
While a single-joint muscle can produce motion only at the joint it crosses, a multijoint muscle can produce motion at more than one joint. This is of advantage in many human movements. However, multijoint muscles can become inefficient when trying to exert full active or passive motion at two or more joints at the same time.
Which muscles are active and passive insufficiency?
Think about which muscles these are first to fully grasp the concepts, namely: the hamstrings, the biceps, the triceps, the digital flexors and extensors, the gastrocnemius.
What is active insufficiency?
Active insufficiency occurs when a multi-joint muscle shortens over BOTH joints simultaneously, and hence, creates so much slack, that muscle tension is almost completely lost. Active Insufficiency: Knee is flexed, hip is extended, hamstring is shortened and in a weakened position. Think about when you flex your knee and then attempt ...
Can a standing calf raise hit both gastroc and soleus?
Better: A standing calf raise that will hit both gastroc and soleus simultaneously.
What is passive insufficiency?
Passive insufficiency. Click card to see definition 👆. Tap card to see definition 👆. 2 joint muscles cannot be stretched. enough to allow full ROM in both. joints at the same time. ex: the hamstring muscles is long enough to be stretched over each joint individually (hip flexion or knee extension) but not both.
Why is hip flexion limited?
With the knee flexed, the hamstrings are being stretched over one joint. This limitation of hip flexion is due to lack of flexibility of the hamstrings.
Where is the latissimus dorsi located?
The proximal attachment of the latissimus dorsi is on the spinous process of the lower six thoracic vertebrae, thoracolumbar fascia, and iliac crest; its distal attachment is on the humerus (Moore, p. 700). Because it does not cross the elbow joint, flexing the elbow would not affect its mobility.
Can 2 joint muscles exert enough tension?
2 joint muscles cannot exert enough. tension to shorten enough to allow full. ROM in both joints at the same time. (For example, the finger flexes cannot produce a tight fist when the wrist is fully flexed, as they can when it is in neutral position.
What is passive insufficiency?
Passive insufficiency occurs when a multi-joint muscle is lengthened to its fullest extent at both joints, but also preventing the full range of motion of each joint it crosses. [6] Image: Quadriceps passive insufficiency - Most of use would have reached our quadriceps length of passive insufficiency by now.
Can passive insufficiency cause injury?
When considering sports activities like sprinting or kicking a ball, passive insufficiency of the hamstring complex can cause injury. If a client seems to consistently struggle with particular movements you can determine if active or passive insufficiency is playing a role and adjust accordingly. [1]
