No. Question
1a What is the relative risk of sustaining a traumatic and/or stress fracture for a given decrement in bone mineral density, or alteration in bone geometry, in an astronaut-equivalent population who are physically active?
1b Will a period of rapid bone loss in hypogravity be followed by a slower rate of loss approaching a basal bone mineral density (BMD)? What are the estimated site-specific fracture risks as one approaches basal BMD?
1c Is there an additive or synergistic effect of gonadal hormone deficiency in men or women on bone loss during prolonged exposure to hypogravity?
1d What biophysical modalities, nutritional modifications, and pharmacological agents (alone or in combination) will most effectively minimize the decrease in bone mass due to extended hypogravity exposure?
2j Will different technologies be needed to treat either open or closed fractures in a space environment?
3a What is the cause of the back pain commonly experienced by crewmembers upon return to 1-G?
3b Is damage to joint structure, intervertebral discs, or ligaments incurred during or following hypogravity exposure?
3c What countermeasures will protect joint and intervertebral soft tissues (e.g. discs and ligaments) from microgravity or partial gravity-related damage?
3d What rehabilitative measures will hasten recovery of soft tissue damage in a partial gravity environments, or upon return to Earth's gravity?
4a What diagnostic measures permit detection of renal calcification during extended-duration space flight?
4b What nutritional and/or pharmacological countermeasures adequately minimize risk of stone formation in-flight and upon return to 1-G?
