Figure 4From: TRACE (Trunk Aesthetic Clinical Evaluation), a routine clinical tool to evaluate aesthetics in scoliosis patients: development from the Aesthetic Index (AI) and repeatability Waist asymmetry as evaluated in TRACE: it was quite easy to define a total asymmetry (a score of 4) when one flank was straight or when there was a lateral decompensation of the trunk. It was easy as well to define a very slight (a score of 1) and an important but not complete (a score of 3) asymmetry; between these points we defined a mild asymmetry (a score of 2). In the figure, from the top: slight (1), mild (2), moderate (3) and important (4) asymmetry.Back to article page
