Of every 1,000 children, three to five develop spinal curves that are considered large enough to need treatment. Scoliosis can be detected by uneven shoulder height, loss of structural balance, a change in posture or unequal leg length. Here is a quick test you can perform on children of any age.
#1- Have the child lie face down on a bed with their feet hanging off the edge. The legs should be kept together with their arms resting at their side.
#2- During the test, their head must be facing straight down. Check to see if one leg appears shorter.
#3- Test further by bending their legs up at the knees and compare again. A short or contracted leg is a common condition that can lead to scoliosis related problems.
