Spasticity is another movement condition that occurs commonly in neurological disorders. This condition may also be present in combination with other disorders. It involves an abnormal stiffness, tightness, or directional “pull” of muscles. This condition prevents the patient from stretching or opposing involuntary contraction of muscles. This can lead to hyperflexia, or overly flexed joints. Spasticity may be treated with medication, surgery, or rehabilitation/physical therapy.
