Scissor gait of the lower limbs is a clinical manifestation of spastic bilateral lower limb palsy in cerebral palsy. The scissor gait is due to the increased muscle tone of both lower limbs, especially the increased tension in the extensor muscles, which causes the lower limbs to be over-extended and the legs to cross in a scissor shape when moving. What are the prevention methods of cerebral palsy? 1. Rubella virus infection should be prevented during pregnancy. 2.Conduct regular health checkups after pregnancy: pay attention to exclude factors of difficult delivery, and actively treat hypertension and diabetes if you have them.
