OSAT Severe-Profound Multiple Disabilities (131) Practice Test

Prenatal spina bifida surgery performed before 26 weeks gestation is associated with a reduced need for mobility aids after birth. Which option best reflects this claim?

It has no effect on mobility aids.

It increases the need for mobility aids.

It is associated with reduced need for mobility aids after birth.

Early prenatal repair of spina bifida aims to protect the exposed spinal cord and support healthier motor development. When surgery is done before 26 weeks, studies have shown better motor outcomes in the affected limbs, which translates into fewer children needing mobility aids like braces, walkers, or wheelchairs after birth. This reflects that reducing ongoing neural damage preserves function enough to lessen the reliance on assistive devices.

It's important to recognize this is an association with improved outcomes, not a guarantee of a cure. The procedure carries risks for both mother and fetus, and results can vary based on lesion level and other factors.

It guarantees a cure.
