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

 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.

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.

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...

"Pediatric upper limb spasticity is a significant concern and can negatively impact a child's development and quality of life," said Mark Gormley, Jr.
In conclusion, the change of the neural excitability after stroke may cause the spasticity which can be released through modulating the activity of the GABA-a receptors in the cerebral cortex by the peripheral injection of the Botox.
Spasticity is more often found in flexor muscles of the upper limbs, and in extensor muscles of the lower limbs [1, 3].
Inclusion criteria were as follows: (1) having chronic phase (at least 12 months) unilateral stroke, (2) having an ischemic or hemorrhagic poststroke hemiplegia, (3) having calf muscle spasticity score; 1+ to 3 by Modified Ashworth Scale (MAS) [11], and (4) being able to reach at least Brunnstrom stage 3 at the leg.
Many investigators have studied the effectiveness of hand splinting in the management of spasticity and contractures with conflicting results.
In an initial study, two physicians trained in spasticity assessment were instructed to test the glove on five different patients with cerebral palsy.
1,2 The disorder varies in the clinical presentation, timing of the lesion, site and severity of the impairments.3 The prevalence of cerebral palsy is reported between 2 and 3 per 1,000 live births.4,5 Spastic CP, particularly spastic diplegia, is the most common form of CP, accounting for 50-60% of total cases.2,6,7 Spasticity has severe adverse effects on muscles and joints, particularly in extremities.1 Both limbs, however, may exhibit difference in pattern of spasticity from each other.4 Spasticity is generally worse in the lower limbs in children with bilateral involvement.6 The most commonly involved lower limb muscles include gastrocnemius, soleus, adductors, hamstrings, psoas and rectus femoris.1,6

About 80 percent of people with MS have spasticity, which ranges from mild to severe.
It is clear from this month's CME that the mere presence of epilepsy or spasticity is not a trigger for surgery.
Editors Stevenson and Jarrett present readers with the second edition of their collection of contributions focused on the neurological symptom spasticity. The editors have organized the contributions that make up the main body of the text in two parts devoted to nine chapters focused on spasticity, assessment of the individual with spasticity, provision of education and promoting of self-management, and other related subjects; and seventeen appendices focused on focal spasticity multidisciplinary proforma, spasticity outcome measures form, managing spasticity and spasms, and many other related topics.
