Risk of Intervertebral Disc Damage after Prolonged Space Flight

Investigator: Jeffrey C. Lotz, PhD
Sponsor: University of California San Diego (UCSD)

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.
