Spasticity is often treated with the drug baclofen, which acts as an agonist at GABA receptors, which are inhibitory. Spastic cerebral palsy is the most common form of cerebral palsy, which is a group of permanent movement problems that do not get worse over time. GABA's inhibitory actions contribute to baclofen's efficacy as an anti-spasticity ...
It is seen in disorders such as cerebral palsy, stroke, and spinal cord injury. Rigidity is a severe state of hypertonia where muscle resistance occurs throughout the entire range of motion of the affected joint independent of velocity. It is frequently associated with lesions of the basal ganglia. Individuals with rigidity present with ...
Spastic cerebral palsy is caused by malformation of or damage to the parts of the brain that control movement. [12] What exactly makes some children susceptible to such brain damage is often unknown but it is believed that cerebral palsy may be the result of causal pathways, or chains of events that cause or increase the likelihood of brain injury.

Spastic cerebral palsy is the type of cerebral palsy characterized by spasticity or high muscle tone often resulting in stiff, jerky movements. [110] Itself an umbrella term encompassing spastic hemiplegia, spastic diplegia, spastic quadriplegia and – where solely one limb or one specific area of the body is affected – spastic monoplegia.
Spasticity also is velocity-dependent, [14] but, differently from oppositional paratonia, if repeatedly elicited decreases instead of increasing. [15] Conversely, parkinsonian rigidity is independent from movement velocity and probably also from movement repetition.
Spastic diplegia is a form of cerebral palsy (CP) that primarily affects the legs, with possible considerable asymmetry between the two sides. It is a chronic neuromuscular condition of hypertonia and spasticity in the muscles of the lower extremities of the human body, manifested as an especially high and constant "tightness" or "stiffness", [1] [2] usually in the legs, hips and pelvis.
The incidence of cerebral palsy has increased in the past 40 years. It has been estimated that, in the United States, cerebral palsy occurs in four out of every 1000 births. [11] Of those births, about 20–30% have spastic hemiplegia. Overall, spasticity is the more common type of cerebral palsy and non-spastic cerebral palsy is less common.
Ankle clonus. Clonus is a set of involuntary and rhythmic muscular contractions and relaxations. Clonus is a sign of certain neurological conditions, particularly associated with upper motor neuron lesions involving descending motor pathways, and in many cases is accompanied by spasticity (another form of hyperexcitability).
