Table 2.

Major DXA findings. Baseline refers to pre-discharge DXA; Completion, at the end of study (approximately 12 months post discharge; C, active control group; and E, assisted exercise group. BMC is bone mineral content and BMD is bone mineral density. Note that each DXA measure demonstrated significant change across study duration (p < 0.005)
