G82.4: Spastic tetraplegia

Spastic tetraplegia is a form of cerebral palsy that results in muscle stiffness (spasticity) in all four limbs - both arms and both legs. It comes from abnormalities or damage in the brain that disrupts the brain's ability to adequately control movement and posture. Those with spastic tetraplegia may struggle with coordination and balance, and their movements may appear stiff or jerky. This condition may also be associated with intellectual disabilities, seizures, or problems with vision, hearing, or speech. Lastly, a variety of early life factors, such as premature birth, low birth weight, or infections during pregnancy might increase the risk of this condition, although the exact cause is often not known.
