Histomorphometric 2D parameters of cancellous bone in L4 lumbar vertebrae. Parameters are a mineral apposition rate (MAR), b mineralized surface percent (MS/BS), c ratio of bone formation rate to bone surface area (BFR/BS), d ratio of bone formation rate to bone volume (BFR/BV), e osteoblast surface area per unit bone surface area (Ob.S/BS), f osteoclast surface area per unit bone surface area (Oc.S/BS), and g osteoclast number per unit surface area (N.Oc/B.Ar). As in Fig. 2b, individual values are shown, asterisks over connected pairs indicate significant differences, and a poundsymbol indicates a significance difference (P < 0.05) between the Baseline and Sham-Walking groups
