Summary

Study with the aim to see the effect on a space ground anaologue, Hyperbuoyancy Floatation (HBF) on cervical column.

Detailed description

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.

Conditions

• Intervertebral Disc Herniation
• Stiffness; Spine

Interventions

Type	Name	Description
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.
