Pertubation device for propioception and vestibular training

A portable perturbation apparatus for proprioceptive and vestibular training and therapy comprising:

• a stationary base;
• a first platform assembly mounted on an upper surface of the base;
• a second platform assembly mounted on an upper surface of the base,
• the first and second platform assemblies disposed in spaced relation and aligned along a longitudinal centerline of the base,
• the first and second platform assemblies being independently movable in X-Y planar motion relative to each other and relative to the base;
• the first platform assembly comprising:
• an X-axis carriage (X1) mounted to the base, a motor and powertrain (X1M) configured to drive motion of the X-axis carriage (X1) relative to the base, a Y-axis carriage (Y1) mounted to the X-axis carriage (X1), a motor and powertrain (Y1M) configured to drive motion of the Y-axis carriage (Y1) relative to the X-axis carriage (X1);
• and
• a first foot pad removably mounted to the Y-axis carriage (Y1);
• the second platform assembly comprising:
• an X-axis carriage (X2) mounted to the base, a motor and powertrain (X2M) configured to drive motion of the X-axis carriage (X2) relative to the base, a Y-axis carriage (Y2) mounted to the X-axis carriage (X2), a motor and powertrain (Y2M) configured to drive motion of the Y-axis carriage (Y2) relative to the X-axis carriage (X2);
• and
• a second foot pad removably mounted to the Y-axis carriage (Y2);
• a motor controller in independent electrical communication with each of said motors X1M, X2M, Y1M, Y1M;
• and
• user programmable computer code residing in a memory and in communication with said motor controller, wherein said motor controller is programmable and operable for independent control of each of said motors to perturbate a user disposed on said first and second foot pads.
