Risk of Intervertebral Disc Damage after Prolonged Space Flight
Location(s): United States
Back pain and intervertbral disc (IVD) damage are common problems experienced by astronauts. We hypothesize this is from paraspinal muscle deconditioning, ∼5 cm body lengthening from spinal swelling and straightening, and biochemical tissue changes.
Objective Examine morphological changes in the lumbar spine induced by spaceflight.
