Pre-op Exercise for AIS Surgery

The goal of this clinical trial is to determine if pre-operative scoliosis-specific exercises have a beneficial effect on the health outcomes of surgery for adolescent idiopathic scoliosis. Adolescent idiopathic scoliosis affects adolescents between the age of 10-18. The main questions this study aims to answer are: * Can pre-operative exercises help reduce curve progression prior to surgery? * Can pre-operative exercises help improve the surgery outcomes, such as a lower number of vertebrae needing fusion, increased curve correction, reduced surgery length, and shorter length of stay in the hospital? * Can a pre-operative exercise intervention result in a reduction of the cost of surgery? Researchers will compare the current standard of care (the control group) to an intervention group (with pre-op exercises) to see if pre-op exercises have an effect on these outcomes. Participants will: * visit the clinic every 3 months to complete ultrasound imaging scans and questionnaires * if given an exercise intervention, aim to complete it for roughly 30 minutes a day
