Both active and passive insufficiency are functional states that occur in
multi-joint muscles only
. … 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.
What is the difference between passive and active insufficiency?
Both active and passive insufficiency are functional states that occur in
multi-joint muscles only
. … 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.
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.
What causes muscle insufficiency?
Many health conditions can cause muscle weakness. Examples include: neuromuscular disorders, such as muscular dystrophies,
multiple sclerosis
(MS), amyotrophic lateral sclerosis (ALS) autoimmune diseases, such as Graves’ disease, myasthenia gravis, and Guillain-Barré syndrome.
What would be an active insufficient position of the quadriceps muscle?
Simply stated, active insufficiency occurs when
a muscle that crosses two joints (like the rectus femoris) cannot produce force equally across the two joints
. The rectus femoris enters active insufficiency when the hip is flexed, because it cannot also contract at the knee joint.
What is the position of 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
. This is generally less likely to be as problematic as active insufficiency.
Why is passive ROM greater than active?
ROM can be measured as either active or passive. Active ROM is created by the person contracting the muscles around that joint. Passive ROM is created by an external force pushing on the body around the joint (e.g., a partner, an opponent, a piece of equipment).
Passive ROM is always greater than active ROM
.
Which of the following is the two joint muscle?
Answer:
Sartorius
is a two joint muscle.
What is passive muscle tension?
Passive tension was
the tension which was present in the absence of evidence of active muscle contraction
. It is possible that when the muscle was stretched, stretch reflexes were aroused causing active contraction of the muscle.
What is the proper name for the hamstring muscle?
The
semitendinosus, semimembranosus, and biceps femoris
muscles comprise the hamstring muscle group. … The distal hamstrings form the superolateral (biceps femoris) and superomedial (semimembranosus and semitendinosus) borders of the popliteal fossa.

How do you treat muscle fatigue?
Be sure to stretch before and after strenuous activity. Warming up can loosen your muscles and protect against injury. If your muscle fatigue persists,
hot and cold therapy
are techniques that can reduce inflammation and discomfort. Other cases of muscle fatigue may require medical attention.
What are the symptoms of muscle weakness?
- Burning feeling.
- Frequent episodes of falling.
- Loss of muscle coordination.
- Muscle spasms.
- Pain.
- Paralysis.
- Pins-and-needles (prickling) sensation.
- Twitching.
How do you make the gastrocnemius actively insufficient?
Let’s make the gastrocnemius actively insufficient by
pulling the foot towards the knee, or dorsiflexing the ankle
. When dorsiflexing, or pulling the foot towards the knee, the gastrocnemius is in a longer position. The length makes it harder to create adequate force to extend the ankle or flex the knee.
What is triceps passive insufficiency?
The biarticulate long head of the triceps brachii [1 ] enters passive insufficiency through
the completion of elbow flexion when the shoulders are more flexed and abducted
or through the completion of shoulder flexion and abduction when the elbows are more flexed.
What happens to a joint when a muscle that crosses over it flexes?
A
multiarticulate
muscle, such as the flexor digitorum profundus in the hand, crosses two or more joints (Figure 1). During a concentric contraction, a muscle shortens and its two ends move toward each other. … The hamstrings, on the other hand, create extension at one joint (the hip) and flexion at another (the knee).
