What does the term spastic refer to in medical terms?

In medical terminology, the term "spastic" specifically refers to a condition characterized by increased muscle tone, which often results in tightness and stiffness. This is commonly seen in conditions such as cerebral palsy or after certain types of brain injuries, where muscle control is impaired.

When muscles are spastic, they are not only tight but may also lead to reduced mobility or movement. This tightness can make physical movement difficult and can result in abnormal postures or muscle contractions. It is essential to distinguish spasticity from weakness or immobility stemming from different causes, as the management and treatment may vary based on the underlying issue.

Understanding this context clarifies why the definition linked to "tight and immobile" is accurate, as it encapsulates the essence of spasticity, making it crucial to recognize in medical discussions and treatment planning.
