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.
Healthy infants with normal physical development and no need for physical therapy intervention
Infants with abnormal head shapes (plagiocephaly or craniosynostosis)
Infants with growth abnormalities (such as genetic conditions)
Infants with developmental delay significant to warrant physical therapy or occupational therapy
Parallel
Repositioning Therapy
Other interventionCaregivers will be instructed how to increase tummy time activities and reshape their infant's heads using at-home methods to direct their attention to the non-preferred side.
Cranial Remolding Orthosis
DeviceA custom cranial remolding orthosis (FDA Class II device) will be made to fit affected infants. this should be worn 23 hours per day and the Orthotist needs to be seen regularly for adjustments until the head shape is resolved.
Final Head Shape
Cranial measurements will be used to assess residual cranial deformation in affected infants. A group of unaffected, typically-developing infants will be used as normal growth examples. Measurements include 2-dimensional measurements (taken at the greater equator of the skull with cranial calipers or a measuring tape): Cranial circumference, medio-lateral dimension of the skull, anterior-posterior dimension of the skull, two opposing diagonal measurements taken 30 degrees from the mid-sagittal line. These will be used to calculate the asymmetry and proportion of the skull and track growth. Measurements include 3-dimensional measurements: 1) An FDA-approved non-invasive, eye-safe laser scanner called the STARscanner will be used to track measurements throughout treatment. For those who switch to Cranial Remolding Therapy, this scanner will be used for custom helmet fabrication. 2) The 3dMD system will use photographs to create a 3-dimensional rendering of your child's head.
Overall Change in Head Shape
The improvements seen in each of the 2 treatment arms will be compared to determine if one treatment has a greater impact than the other treatment. Specifically, the difference between the baseline measurements (taken at 2 months of age) and the updated measurements (taken at each study measurement timepoint) will be compared in 2-dimensions and 3-dimensions. The group with greater correction to the cranial deformity would be considered the more impactful treatment method.
Compliance with treatment
Overall compliance with each treatment method will be assessed. Caregivers of affected infants will be given surveys at each follow up appointment to assess adherence to the treatment arm's protocol. Surveys will include questions specific to the infant's treatment arm, which may include questions such as how long the child remains in a repositioned position before moving themselves, how many hours per day the infant is wearing their custom helmet, and how often caregivers are performing the recommended neck stretches. No surveys will be given to the typically-developing control group as there is no active treatment for this group.
