“…In this study, both kyphosis and lordosis angles were evaluated by SPA measuring from 3D CUS images, instead of Cobb's angle, because lateral radiographs were not available for the majority of patient (not a routine practice). It is generally believed that spinal orthosis could possibly induce a reduction in the kyphosis [1,3,4,5,25]. But more evidence is needed to prove that the reduction in kyphosis caused by spinal orthosis could lead to hypo-kyphosis/ lordosis.…”
