Comparison between vibrations applied during unloading vs reambulation.

Longitudinal changes in (A) bone marrow area (Ma.Ar), (B) trabecular bone volume (BV), and (c) trabecular bone volume fraction (BV/TV) of the tibial metaphysis in mice that either received vibrations only during the unloading period (VIB-HU, n = 6) or only during reambulation (VIB-RA, n = 6). Open triangles correspond to-cross-sectional data of age-matched control mice (n = 12). Relative differences and p-values are given for the comparison between VIB-HU and VIB-RA mice.
