what is the meaning of "clasp-knife spasticity"?

Question

What is the meaning of cerebral palsy spastic diplegia?

Answer 1

Involuntary tightness: This occurs with certain types of strokes, and with spinal cord injuries. Involuntary tightening of the flexor muscles, with intermittent gear as you try to passively straighten a muscle out or extended from the flex position.

Answer 2

Spastic tone: In patients with spasticity the arms and legs are stiff and move with difficulty. A very specific form of stiffness will cause a form of release during movement which is similar to the sudden release when a clasp knife releases. The tone can be very tight, then releases, then tightens again. This is the classic findings in spastic cerebral palsy.

Answer 3

Resistant muscle: Spasticity is complex: it is an increase in muscle resistance, typically more noticeable when a muscle is placed on stretch quickly (it is "velocity-dependent"), creating stiffness/tightness. If untreated it can lead to rigidity or contractures. It is seen most commonly in injuries/illnesses affecting the spinal cord and/or brain. Treatment includes stretching, positioning, bracing, and medication.

Answer 4

Velocity dependent: While spasticity has taken on many colloquial meanings, the true meaning is that of a velocity dependent resistance to stretch. A spastic muscle may be able to be stretched slowly, but when the velocity is increased, the stretch causes a reflexive contraction within the muscle to antagonize the stretch. It is very commonly seen in upper motor neuron related diseases (stroke, cp, etc).

Answer 5

Yes: Both drug and non-drug approaches can be very helpful. Physical therapy can direct you in helpful stretching exercises. Medications such as tizanidine, baclofen, clonazepam, diazepam have all been used to address the mechanisms of spasticity.

Answer 6

Muscle relaxants: Use of a muscle relaxant such as Baclofen is useful in treating spasticity associated with multiple sclerosis. Stretching exercises are often taught by physical therapy to reduce, and prevent muscle spasms and keeping them from tightening up.

Answer 7

Not super, but: Research is focusing on the area. Baclofen and tizanidine are usual drugs, but diazepam may be selected. If the spasticity is bad, BOTOX or a baclofen pump may be useful. I think physical therapy can be beneficial. Would propose consideration for one of the research trials. Some of my patients feel medical marijuana is useful.. Some data out of Europe supports this.

Answer 8

HYPERTONICITY: Hyper tonic movements may be considered as extrpyramidal signs which means a disorder of the basal ganglia which are a structure in the brain controlling the muscle functions, usually Dopamine is the main neurotransmitter responsible for that. Parkinson disease is one of that disorder which caused by depletion of Dopamine in the brain.

Answer 9

Spasticity: Diagnosis involves nerve conduction velocity studies, electromyography, and exclusion of other disorders via MRI and laboratory tests. Treatment is supportive. Motor neuron disorders (mnds) are characterized by steady, relentless, progressive degeneration of corticospinal tracts, anterior horn cells, bulbar motor nuclei, or a combination. Symptoms vary in severity and may include muscle weakness.

Answer 10

No: Quadriplegic spasticity itself should not cause global developmental delay. There are, however, conditions that result in both development delay and quad spasticity so although you may see the two together, one does not necessarily cause the other.

Answer 11

Yes: True spasticity as opposed to "muscle spasm" usually occurs secondary to a disorder or trauma, such as a spinal cord injury (sci), a brain injury, a tumor, a stroke, multiple sclerosis (ms), or a peripheral nerve injury. Treatments may include, preventative measures, therapy, positioning/orthotics, oral medication, injectable medication, and in some cased surgical intervention.
