Spasticity is a condition characterized by an abnormal increase in muscle tone or stiffness of muscle, which can interfere with movement, speech, or cause discomfort or pain. In the context of Neonatal Disorders, spasticity is often associated with neurological conditions such as Cerebral Palsy and Hypoxic-Ischemic Encephalopathy (HIE). Understanding spasticity in neonates is crucial for early diagnosis and intervention, which can significantly improve quality of life.
