BMD of the two groups before and during the intervention
There were no significant differences in terms of the lumbar spine and femoral neck BMD between the control and VR groups before the intervention. Moreover, the lumbar spine and femoral neck BMD did not significantly differ between the VR and control groups (2.3% and 2.6% vs 0.4% and 0.6%). The lumbar spine and femoral neck BMD of the VR group increased significantly 12 months after the intervention compared with that of the control group (4.8%, 95% CI 1.2–8.4, Percent change of BMD at lumbar spine and femoral neck after intervention. Results are shown for the percent changes of BMD at lumbar spine (
