Rehabilitation apparatuses, systems and associated methods

A method for moving a supporting element along a three-dimensional moving trajectory, the supporting element being configured to support a body portion of a user, the method comprising:

• receiving a set of user information;
• determining the three-dimensional moving trajectory at least based in part on the received user information;
• moving the supporting element, by a first rod coupled to the supporting element, in a first direction and in a second direction based on the determined three-dimensional moving trajectory, wherein the first direction and the second direction together define a reference plane;
• and
• moving the supporting element, by a second rod coupled to the supporting element, in a third direction based on the determined three-dimensional moving trajectory, wherein the third direction is generally perpendicular to the reference plane;
• wherein the first rod is coupled to a first motor via a first shaft;
• wherein the second rod is coupled to a second motor via a second shaft;
• wherein the second rod includes a first linking member operably coupled to the second shaft and a second linking member operably coupled to the first linking member;
• and
• wherein the second linking member is operably coupled to the first rod.

A system for moving a body portion of a user, comprising:

• a processor;
• a memory coupled to the processor;
• a data storage coupled to the processor and configured to store information associated with a plurality of three dimensional candidate trajectories corresponding to a plurality of treatments for the user;
• a user interface coupled to the processor and configured to receive user information, wherein the processor determines, based on the user information, a three-dimensional moving trajectory from the stored plurality of three dimensional candidate trajectories;
• a supporting element configured to support the body portion;
• a first rod configured to selectively move the supporting element in a first direction and in a second direction, wherein the first direction and the second direction together define a reference plane;
• a first shaft coupled to the first rod;
• a first motor coupled and configured to rotate the first shaft;
• a second rod configured to selectively move the supporting element in a third direction, wherein the third direction is generally perpendicular to the reference plane;
• a second shaft coupled to the second rod;
• and
• a second motor coupled and configured to rotate the second shaft;
• wherein the supporting element is moved in the first, second and third directions by the first and second rods along the three-dimensional moving trajectory.
