The present invention relates to a device which enables a selective therapeutic exercise regimen by providing a tensioning mechanism attached to a rotatable platform along with the unique feature is where two trollies on curved rails operating on X-axis and Y-axis when pressure is applied, will work in unison to travel in any desired direction creating a unique spherically rotational reaction. The platform will react to changes in the operator's weight shifts and center of gravity placed upon it. When this novel multi-rational aspect of the platform responds to subtle changes in the operator's center of gravity, movement of the platform will occur. These changes trigger muscular contractions around the joints of the operator responding to the rotation of the platform while the tensioning mechanism allows for selective resistance to the free movement of the platform enabling selective exercise and therapy routines for various muscle groups. Additionally, the present Multi-Planar Rotational Platform and Suspension Device offers easy scalability and uniform or non-uniform scaling in the X-axis, the Y-axis and / or the Z-axis.
