Spastic CP typically involves increased muscle tone and difficult or unusual movements. Spastic diplegia (or diparesis) is a subtype of spastic cerebral palsy in which the legs are the most affected limbs. People with spastic diplegia often have a "scissor walk," characterized by the knees turning inward/crossing. This is due to tightness in the hip and leg muscles. In some cases, the arms may also be affected, although usually to a lesser degree . Reference: GHAI Essential pediatrics, 8th edition', 'role': 'assistant'}]
