Lumbar Spine Paraspinal Muscle and Intervertebral Disc Height Changes in Astronauts After Long-Duration Spaceflight on the International Space Station
The data reveal lumbar spine PSM atrophy after long-duration spaceflight, and this project aims to promote spine health and prevent spinal injury during space missions and here on Earth.
Pathophysiology of low back pain during exposure to microgravity.
Further studies of countermeasures are recommended to prevent excessive spinal elongation and disc expansion, reduce low back pain in microgravity, and simulate 1-G disc homeostasis, which may also help prevent HNPs postflight.
From the international space station to the clinic: how prolonged unloading may disrupt lumbar spine stability.
Back pain in space and post-flight spine injury: Mechanisms and countermeasure development
RISK OF INTERVERTEBRAL DISC DAMAGE AFTER PROLONGED SPACE FLIGHT
The data support the idea that decreased gravitational forces on the IVDs, during prolonged microgravity, increases their water content but decreases proteoglycan, which increases disk degeneration risk on Earth.
