2022-02-14 07:49:01 A 3-year-old girl is brought to the office due to leg stiffness. Her mother reports that the patient is a clumsy walker and requires assistance to ambulate. The patient was born preterm and has delayed developmental skills. Physical examination shows increased knee and ankle reflexes and clonus at the ankles bilaterally. Muscle tone of the upper extremities and neck is also mildly increased. MRI of the brain reveals periventricular leukomalacia suggestive of cerebral palsy. An oral medication is prescribed that reduces the extremity stiffness.
