Mean percentage (+ or - 1 standard deviation) of muscle fibers volume along the spine for the IL (left column), LO (middle column) and SP (right column) muscles. Results for the NS, the PS and the S patients are respectively presented in the upper, middle and lower row. Within each group of patients, the continuous line represents the data on the right or convex side and the dotted line those on the left or concave side. On the middle and lower panels of IL, the thick horizontal dotted lines indicate the apex position of the spinal deviation of the PS (right convexity) and S patients (left convexity).
