Pediatric physical therapists (PTs) have long struggled to diagnose and treat congenital muscular torticollis (CMT) at early stages, when such diagnosis and treatment would do the most good. Much of this problem is that very young infants and toddlers have difficulty with poses, are difficult to measure due to their small size, lack of compliancy, and inability to remain stationary. It often takes a team of pediatric PTs to perform these measurements, and usually in a clinical setting. We wish to create a toolset and a methodology that allows for simpler diagnostics, more comprehensive monitoring and treatment, and wider access to such care and treatment by creating TorticollisAR – an Augmented Reality (AR) application that performs critical measurements in a familiar, convenient setting (such as the home). The app uses tracking markers integrated into either bands or clothing to take measurements in real-time and while the subject is in motion.
