Spasticity involves increased muscle tone and reflexes, not a complete loss of tone. This description is more in line with hypotonia or atonia. C) Incorrect. Spasticity is not used to describe normal, healthy muscle tone. It is a term associated with abnormal muscle tone often observed in neurological conditions. D) Incorrect. Spasticity is not associated with decreased muscle tone and flaccidity. In fact, it is characterized by increased muscle tone and stiffness.
