MollyNovato, CaliforniaNicolas, 5, tort & plagio, STARband (CIRS Oakland) 4/24/06-9/12/06, Graduate!, 7.5, 11 -----Original Message-----From: Plagiocephaly [mailto:Plagiocephaly ] On Behalf Of TanjaSent: 5 January 2011 2:55 PMPlagiocephaly Subject: DO NOT UNDERSTAND MEASUREMENTS! My 6 month old son has been wearing a star band helmet for 1 month now. I never really thought he needed it but my husband really wanted him to wear the helmet because it looked like he had a slight case of plagiocephaly so I decided to do it. These are my son's measurements after the last scan Cephalic Ratio: 82% (started at 83%)Cephalic Ratio (CR) = Cranial Breadth / Cranial Length.  An ideal ratio would be 0.78 or 78%Brachycephaly Severity - normal - 73-83%; moderate - 83.1% to 87.9%; severe - 88% and higher.  RSI: 0 mm (started at 0 mm)Radial Symmetry Index (RSI) = from the front of the head, 15° segments are measured and added.  The addition of the right side segments is subtracted to the addition of the left side segments. An ideal ratio would be left side – right side = 0 (<30 mm normal) Cranial Vault Asymmetry Index; 1.43 (started at 4.26)Cranial Vault Asymmetry Index (CVAI):  the percentage difference in plagio, (100%-(US1/US2)).  0-3 mm normal Ear Shift: 20mm (started at 6mm)Ear Offset - this number seems to be very subjective because the ortho places stickers near the ears that the machine picks up to take this measurement.  If they are placed differently each time the number will come out differently There are a bunch of other numbers here. Am I supposed to be looking at something else? What do these numbers mean? Here are descriptions of what some of the other numbers on the STARscanner report mean: · Oblique Cranial Maximum and Minimum = Ideally one is looking to have the maximum line vertical and the minimum line horizontal.  · Oblique at 30 deg (US1 and US2) = Length of diagonal taken at 30° on each side (30° corresponds to the corner of the eye).  The subtraction of US1 and US2 gives an indication of the asymmetry of the head.  An asymmetry between 0-3 mm is normal; <6 mm is very mild; 6-10 mm is mild; 10-15 mm is moderate; 15+ mm is severe· Q1, Q2, Q3, Q4 volumes: Draws vertical and horizontal lines centered on middle point of head.  Measures volume of each corner starting front left, then front right, back right and back left.· Anterior Symmetry Ratio: looks at front of head and divides front left volume with front right volume.  An ideal ratio would be 1· Posterior Symmetry Ratio: looks at back of head and divides back right volume with back left volume.  An ideal ration would be 1· Overall Symmetry Ratio: Divides left side with right side.  An ideal ratio would be 1· Upper facial left and upper facial right: Measures the length between the centre of the front to each left and right ear.  This corresponds to a cranial bone and determines the position of the ear.· Upper Facial Symmetry Ratio: Divides Upper Facial Right with Upper Facial Left. An ideal ratio would be 1

I didn't understand the numbers when we started either. When I asked the tech, she did a great job explaining what they all meant. They are mostly for ins. purposes.

Good luck. You will be pleased.
