my last ortho c&p exam noted that i had abnormal gait due to my minimal scoliosis. i remained at 40 percent (although was awarded IU). for the record, i have 5 herniated discs, foraminal and spinal stenosis, a slipped vertebrae, 2 torn discs, abnorminal lordosis and arthritis plus the minimal scoliosis. i was at 12 percent in like 2007 and have never been remeasured.
i wish you well but from what i have read, i don't feel confident or comfortable thinking you will get to 20 percent. good luck!
