ABSTRACT:
A medical chair has a cranium position regulating device and a pelvis-and-knee position regulating device for respectively regulating the positions of the cranium and pelvis of a subject who sits on a seat. The cranium position regulating device and the pelvis-and-knee position regulating device have structures in which they butt against both right and left sides of the cranium and the pelvis, respectively, to cause both planes centered in a right-and-left direction of the cranium and the pelvis to be in a same central plane which extends in the direction of gravity. An ideal condition of the body of the subject in which vertical and horizontal balances are achieved against the force of gravity can be achieved to ensure physiological curvature of vertebrae and the condition can be maintained.
