Determine spaceflight deconditioning effects in the lumbar, thoracic, and cervical spine

1. Quantify vertebral geometric, volumetric, cortical thickness, and vBMD changes and spinal muscle volume changes in pre- and post-flight medical images of crewmembers on long-duration ISS missions.

2. Quantify vertebral strength and assess injury risk in dynamic simulations with a human body model (HBM) altered to represent long-duration ISS crewmembers’ pre- and postflight vertebrae and spinal musculature.

Integration/Unique Aspects: Obtain data from LSDA
