Fig. 2

Results of Magnetic Resonance Imagining (MRI) and Dual-energy X-ray absorptiometry (DXA) are presented (A) Top: the evolution of the maximal Cross-Sectional Area (maxCSA) for each pilot is shown. In the bottom part of the figure a representative image shows the evolution of maxCSA for one pilot (S03). (B) The boxplots related to T-scores for each pilot are reported together with the threshold value of osteoporosis. In (C) the difference between the T-score at T0 and T2 are plotted for the lumbar site, femoral neck, and sites of distal femur and proximal tibia for both legs (to improve the readability of the figure, only 4 sites of distal femur and proximal tibia were plotted for each leg, the images of the different bone site are from BioRender.com). The number reported in brackets refers to specific sites according to the Toronto Rehab Protocol. Positive differences correspond to improvements of the bone density while negative ones to a decrease
