Study with the aim to see the effect on a space ground anaologue, Hyperbuoyancy Floatation (HBF) on cervical column.
the aim of the study is to determine the effect of 4h HBF and subsequent passive 1g axial loading upon stature, cervical IVD height) cervical muscle (Longus Collis and Semispinalis Cervicis) thickness and CSA assessed with ultrasound, cervical vertebral compliance, their relationships to induced stature increments and neck pain.

NASA astronaut criteria (1.57-1.90m, 50-95kg)
Exclusion Criteria:
Subjects must remain to the exposure of gravity (1G) after 4h of hyperbuoyancy floatation(spine unloading)
Device: Hyperbuoyancy Floatation
Subjects are laid supine upon a HBF waterbed encased within a wooden frame partially (50%) filled with water (at 36ºC to maintain thermal comfort) super-saturated with magnesium sulphate. Thus, subjects are buoyant, sinking passively into the bed in proportion to their segmental mass.
Height
Standing stature measured by a commercial stadiometer (Seca 217, Germany)
Time frame: up to 2 years
Height of cervical Intervertebral Discs
Disc height (C3-T1) measured by ultrasound (Samsung HS40, South Korea)
Time frame: up to 2 years
Longus Collis and Semispinalis Cervicis thickness and cross-sectional area.
Neck flexor (Longus Collis) and Neck extensor (Semispinalis Cervicis) were assessed by ultrasound (Samsung HS40, South Korea) and their respective muscle thickness and cross-sectional area was calculated.
Time frame: up to 2 years
Vertebral Stiffness
Vertebral stiffness from C0 to L5 was assessed passively (in the prone position) with a handheld differential vertebral compliance transducer (PulStar, Sense Technology Inc., USA) in Newtons.
Time frame: up to 2 years
Self-reported neck pain
Pain rating scale (CHAPS) from 0 to 10
Time frame: up to 2 years
