Patent ID: 7404221

Claim:
A motion platform for providing periodic acceleration to a subject, comprising: a box frame providing a foundation of the motion platform, said box frame having four wheel tracks located substantially at the four corners of the top portion of the box frame; a drive module having four track wheels located substantially at the four corners of the top portion of the drive module, wherein said track wheels extend from the top portion of the drive module and rest in the wheel tracks of the box frame, whereby the drive module sits within the box frame and is operably movable relative to said box frame; a support connected to said drive module, said support comprising a planar surface for supporting the subject, said planar surface having a head end and a foot end; and said drive module comprises a displacement module for providing periodic acceleration to the subject by moving the drive module in a line parallel to the planar surface of the support, and the periodic acceleration is alternately in the direction of the head end, and the foot end, of the planar surface, the movement of the drive module having a force in a range of about 0.1 g to about 0.4 g such that the motion platform adds pulses to the fluid filled channels of the body of the subject, the displacement module being connected to said box frame only through said drive module, whereby the displacement module is not directly connected to said box frame.
