spasticity

 [spas-tis´ĭ-te]
continuous resistance to stretching by a muscle due to abnormally increased tension, with heightened deep tendon reflexes.
clasp-knife spasticity clasp-knife rigidity.

spas·tic·i·ty

(spas-tis'i-tē),
One type of increase in muscle tone at rest; characterized by increased resistance to passive stretch, velocity dependent and asymmetric about joints (that is, greater in the flexor muscles at the elbow and the extensor muscles at the knee). Exaggerated deep tendon reflexes and clonus are additional manifestations.
See also: clasp-knife spasticity.

spasticity

/spas·tic·i·ty/ (spas-tis´ĭ-te) the state of being spastic; see spastic (2).

spasticity

[spastis′itē]
Etymology: Gk, spastikos, drawing in
a form of muscular hypertonicity with increased resistance to stretch. It usually involves the flexors of the arms and the extensors of the legs. The hypertonicity is often associated with weakness, increased deep reflexes, and diminished superficial reflexes. Moderate spasticity is characterized by movements that require great effort and lack of normal coordination. Slight spasticity may be marked by gross movements that are coordinated smoothly but combine selective movement patterns that are uncoordinated or impossible.

spasticity

 Neurology A velocity-dependent ↑ in tonic stretch reflexes–involuntary muscle contraction, most common in Pts with spinal cord lesions above the conus medullarisis, developing months after spinal cord injury Management Baclofen, which potentiates GABA's inhibitory effect on reflexes

spas·tic·i·ty

(spas-tis'i-tē)
A state of increased muscular tone with exaggeration of the tendon reflexes.

spasticity

Rigidity in muscles causing stiffness and restriction of movement. Spasticity may or may not be associated with paralysis or muscle weakness. Spasticity with paralysis is a feature of many cases of STROKE. It occurs in SPASTIC PARALAYSIS (cerebral palsy) and sometimes in MULTIPLE SCLEROSIS.

Spasticity

Increased mucle tone, or stiffness, which leads to uncontrolled, awkward movements.

spasticity

increased muscle tone and exaggerated tendon reflexes; characteristic of upper motor neurone lesion

spasticity,

n hypertonicity of muscles associated with increased tendon reflexes.

spas·tic·i·ty

(spas-tis'i-tē)
Type of increase in muscle tone at rest; characterized by increased resistance to passive stretch; velocity dependent and asymmetric about joints.

spasticity (spastis´itē),

n a form of muscular hypertonicity with increased resistance to stretch.

spasticity

the state of being spastic.

inherited neonatal spasticity
signs appear in calves at 2 to 5 days of age. Unable to stand; if lifted rigidity of all muscles with extension of limbs.
inherited periodic spasticity
see inherited periodic spasticity.
inherited progressive spasticity
possibly inherited disease of Angora goats; characterized by development of lethargy and ataxia at about 2 months of age, followed by paresis, recumbency and euthanasia and necropsy lesions of vacuolation in neurons of the brain and spinal cord.

Patient discussion about spasticity

Q. Do you want to end because of a vaccination in a wheel chair? It is already about 12 years ago. I met a mother with her kids. One came always in a wheel chair to the services. His terrible story is still in my mind. It could be shown, that because of a vaccination he got the cytomegalovirus infection (CMV) and then spastic paralysis.

A. Corrigendum: If you know somebody speaking German and English who could...
