Which of the following conditions often requires surgery and exercises to assist mobility?

Spina bifida is a condition that often requires surgical intervention along with exercises to improve mobility. It is a congenital defect in the development of the spinal cord and the surrounding vertebrae. In many cases, this condition can lead to varying degrees of paralysis, mobility challenges, and issues with coordination. Surgical procedures may be necessary to close the opening in the spine, repair the spinal cord, and manage associated complications. Additionally, physical therapy and exercises are crucial for individuals with spina bifida to strengthen muscles, enhance mobility, and improve overall function.

In contrast, while cystic fibrosis and muscular dystrophy may also require interventions and support for mobility, they typically don't involve surgery in the same manner as spina bifida. Cystic fibrosis primarily affects the lungs and digestive system, while muscular dystrophy is a group of genetic disorders leading to muscle degeneration. Epilepsy is a neurological disorder characterized by seizures and does not typically involve mobility impairment or the need for surgical procedures related to mobility.
