Detecting and Monitoring Scoliosis Without Radiography: Standard Radiographic Monitoring Program Versus Self-Screening With Momentum SpineTM

Inclusion Criteria: * Children between the ages of 8-18 years of age * Confirmed radiographic diagnosis of adolescent idiopathic scoliosis * No history of spinal/ chest surgery. * Participants who have had spine x-rays ±1 week as baseline visit at CHLA will be included in the study. * Participants who have identifiable markings such as tattoos or birthmarks can be included in the study, though their markings will be covered with tape. Exclusion Criteria: * Participants who have had x-rays in a brace will not be included. * Participants who have had an x-ray from another institution will not be included in the study. X-rays from out of community are typically done with a different and lower quality machine then the one at our institution. Additionally, we do not have consent from outside institutions to use their x-rays for research purposes. * Participants with a confirmed pregnancy will not be included. Pregnancy status will be self-reported by participants. * Participants with the existence of a second deformity which may affect topographic assessment will be excluded (e.g. Limb length discrepancy greater than 2cm). * Families who do not speak English and Spanish will be unable to participate as the application is only available in English and Spanish at this time. * Families who do not have access to their own compatible personal smart phone device will be unable to participate in the study.
