Examines spinal shape changes in men after 21 days of dry immersion, suggesting potential impacts of weightlessness.

The aim is to investigate how a simulated microgravity environment affects the shape of the spine.
Studied eight men aged approximately 30 years under dry immersion conditions for 21 days.
Measured spinal shape using Video Analysis-3D Biosoft technology at multiple time points.
Recorded cervical and thoracic angles and assessed changes in lumbar lordosis and scoliosis.
Cervical lordosis and thoracic kyphosis angles increased by 3.8 and 4.7 degrees, respectively, by day 7.
Lumbar lordosis angles varied among subjects; two had a decrease, two had an increase, and one showed no change.
By day 14, average lumbar lordosis angle increased by 3 degrees; scoliosis decreased in three subjects.

Voronov et al. (2025) studied this question.
