Another cause of falls in kids with MS is neurological, Graff says, with the disease attacking the brain and the inner ear’s vestibular system. When the system goes awry, kids feel off-balance, dizzy, or like they’re spinning. To train the system, have your child stand a few feet away, feet together and facing you. Holding a soft, light ball, gently toss it toward the child to catch. Then ask your kid toss it back to you. Once this feels easy, ask your child to balance on one foot, then throw and catch. Do three sets of 10 passes back and forth.
