Spasticity is stiff or rigid muscles. It may also be called unusual tightness or increased muscle tone. Reflexes (for example, a knee-jerk reflex) are stronger or exaggerated. The condition can interfere with walking, movement, speech, and many other activities of daily living.
Spasticity can be treated by physical therapy, occupational therapy, speech therapy, assistive devices, bracing, medication management, as well as botox injections.
