Torticollis

This research involves retrospective and prospective studies for clinical validation of a DystoniaNet deep learning platform for the diagnosis of isolated dystonia.

This study will examine how effective caregiver's repositioning strategies are in correcting an infant's deformational cranial shape, as well as the effectiveness of the use of a custom cranial remolding orthosis for treatment of deformational head shapes. Infants with torticollis will be concurrently enrolled in physical therapy treatment until the torticollis is resolved. A normal, unaffected population will be studied to compare typical growth to the growth of infants undergoing active treatment.

The goal of this clinical trial is to test whether an app-based intervention can reduce the likelihood of a torticollis diagnosis in infants. The main question\[s\] it aims to answer are: * whether an app can successfully deliver an intervention to parents of young infants * whether parents who learn about torticollis will increase behaviors intended to prevent torticollis compared to parents who learn about general infant development Participants will complete a monthly survey for 6 months asking about their parenting behaviors. Researchers will compare parents who receive notifications about torticollis with parents who receive notifications about general infant development to see if increased knowledge of torticollis leads to preventive behavior.
