What are the differences between spastic and flaccid paralysis?

What are the differences between spastic and flaccid paralysis?

Muscle tone: Spastic means tight muscles, flaccid is loose and relaxed muscle. Different causes for each.

Palsy (Definition)

...is a corruption of French "paralise" from Latinized Greek "paralysis." In the old days it meant any kind of persistent weakness. To this day Parkinson's disease is also called "paralysis agitans" which is a Latin translation of Dr. Parkinson's original name for it, the "shaking palsy." We've obviously reborrowed the full form "paralysis" into English as well; today ...Read more

What are the differences between flaccid paralysis and spastic paralysis?

What are the differences between flaccid paralysis and spastic paralysis?

Spasticity: Both types of paralysis involve loss of voluntary motor function. However, in the spastic type, involuntary movements persist, such as with cerebral palsy.

Can you tell me examples of when does one get spastic paralysis vs flaccid paralysis please?

Can you tell me examples of when does one get spastic paralysis vs flaccid paralysis please?

Cord vs root: In general spastic paralysis results from an injury to the spinal cord and flaccid paralysis after an injury downstream from the spinal cord, such as in the nerve root or peripheral nerve. The notable exception is in the early period after a spinal cord injury when there is "spinal shock" with flaccid paralysis.

Why do health agencies track cases of flaccid paralysis?

Why do health agencies track cases of flaccid paralysis?

Infections: The cdc (center for disease control) tracks flaccid paralysis, since many cases are related to infections. Viral influenza and the mononucleosis virus epstein-barr can cause guillain-barre syndrome. West nile virus causes myelitis similar to polio. Tracking the spread of these conditions in the us helps identify the cause, develop vaccines and distribute treatments to affected areas.

How does hypercalcemia cause flaccid paralysis? Not described in my med books.

How does hypercalcemia cause flaccid paralysis? Not described in my med books.

Hyperpolarization: Highly elevated ionized calcium can lead to a variety of symptoms, including dehydration, polyuria/polydipsia, confusion, constipation and sometimes pancreatitis. Asthenia and weakness are common and can progress to a flaccid paralysis. Cardiovascular effects include shortened qt, av block, and brady or tachydysrhythmias. Muscular effects are related to hyperpolarization caused by high calcium.

What can cause flaccid paralysis?

Flaccid: There are many causes of flaccid (loose) paralysis, starting with motor nerve synaptic malfunction (as in myasthenia), motor nerve damage (as in polio or other disorders), certain spinal cord lesions affecting motor control. Rarely certain regions of the brain can also cause flaccid paralysis or weakness. There are also some metabolic conditions. My suggestion is that you consult a neurologist.

How does flaccid paralysis affect you?

Loose and floppy: Flaccid describes very low tone with limbs that are loose and floppy. Spastic describes stiff and tight limbs that can have painful spasms. Paralysis is just the lack of ability to move limbs when you want to.

Flaccid: There are many causes of flaccid (loose) paralysis, starting with motor nerve synaptic malfunction (as in myasthenia), motor nerve damage (as in polio or other disorders), certain spinal cord lesions affecting motor control. Rarely certain regions of the brain can also cause flaccid paralysis or weakness. There are also some metabolic conditions. My suggestion is that you consult a neurologist.

What is the definition or description of: Flaccid paralysis?

No muscle tone: Flaccid paralysis is when the muscles cannot move and are without tone, i.e.flaccid.

What is the treatment of flaccid paralysis?

Need detail: Your question can not be answered without knowing what is paralyses, how long the problem exists and what caused it. In general physical therapy can help.

How is flaccid paralysis related to the polio virus?

Polio: Lmn (lower motor neuron) lesions leads to flaccid flaccid parelysis.

Difference between flaccid and spastic paralysis.?

Tone: The difference is in the tone of the muscles. In people with spastic paralysis, they will often have involuntary movements of their legs or arms and it is very difficult to move the limb by another person like a physical therapy. This is spasticity. A flaccid paralyzed limb has no muscle tone and is limp and easily moved by another.

Is there a difference between cerebral palsy and a spastic hemiparesis?

Is there a difference between cerebral palsy and a spastic hemiparesis?

Categorical: "cp" is a group of chronic motor impairments defined by functional limitations in mobility & hand use from neurological dysfunction, not by underlying cause. Impaired control of movement & posture appears early in life, usually from prenatal brain malformation or injury. Spastic=increased muscle tone with decreased voluntary movement hemi-one-sided paresis-weakness is a form of cp.

What is the difference between cerebral palsy and spastic hemiparesis or diplegia?

Terminology: Spastic diplegia refers to spasticity that primarily affects the legs, and spastic hemiplegia primarily affects one side of the body (arm and leg). Cerebral palsy is a movement disorder caused by damage to an immature brain and can present as either.

What could cause spastic paralysis on the right side of the body?

Central lesion: Brain injury from trauma, bleed, tumor, aneurism, ischemia, infection, or spinal cord injury from similar mechanisms all can cause an upper motor lesion resulting in both paralysis and spasticity simultaneously.

17

17
Is spastic paralysis curable?

No: It is possible to reduce the spasticity to a degree with medications, phyiscal therapy, different treatments like Botox injections, and some fancier treatments like implantable pumps to deliver anti spasticity medication. Unfortunately at this date we do not have a "cure" that can reverse paralysis. I hope we will someday.

What's spastic paralysis?

CEREBRAL PALSY: Spastic paralysis is due to a group of conditions that involves nervous sustem and hypertonicity in the muscles of extremities also called cerebral palsy. Condition is caused by injury and abnormalities in the brain. These happen in the womb or in first two years of life. It may be due to lack of oxygen going to brain. Bleeding in the brain, brain infections, head injury, maternal rubella& sever jaund.

How is spastic paralysis treated?

How is spastic paralysis treated?

See below: Spastic paralysis is a general term for many condition in the brain or spinal cord that cause weakness or paralysis of the limbs as well as spasticity which causes increased abnormal tone in the muscles. The conditions most often associated with this conditions are brain injuries, stroke, spinal cord injury, multiple sclerosis and sometimes als. There are treatments that can reduce spasticity.

What is the definition of spastic paralysis?

Tone of the muscle: When paralyzed muscle shows increased one type of tone then it is callers spastic paralysis.
