An orthostatic hypotension alleviation device comprising an outer casing comprising an aperture extending therethrough; a carriage arranged within the outer casing and configured to be reciprocally displaced towards and away from the aperture along a carriage displacement axis; a spindle arranged on the carriage and configured to rotate about a spindle axis; a tether at least partially wound around the spindle, the tether comprising a distal end extending through the aperture, the tether being arranged such that it can be extended from a retracted configuration to an extended configuration in which the tether is fully extended by pulling the distal end away from the aperture so rotating the spindle about the spindle axis; a spindle biasing mechanism connected to the spindle and configured to apply a biasing torque to the spindle about the spindle axis so as to bias the tether towards the retracted configuration; and, a carriage biasing mechanism arranged within the outer casing connected to the carriage and configured to bias the carriage away from the aperture.

A method for exercising muscles in an ankle, foot, and/or leg of a user includes positioning a foot of a user onto a first body of an exercise device. The first body is spaced away from a second body of the device and pivotably connected to the second body of the device at a pivot axis. The pivot axis is adjacent to a central portion of the first body. The method includes rotating the first body about the pivot axis, with the foot, against a first resistive force. Rotating the first body includes subjecting the foot to a first motion. The method includes positioning the foot onto the second body. The method includes rotating the second body about the pivot axis, with the foot, against a second resistive force. Rotating the second body includes subjecting the foot to a second motion, the second motion being different than the first motion.

A portable exercise device includes a pedal spaced away from and pivotably connected to a base and having a neutral position relative to a pivot axis. The pedal is configured to rotate about the pivot axis in a first direction toward the base and in a second direction, opposite the first direction, toward the base. The device also includes a resistance mechanism configured to exert a force on the pedal about the pivot axis in a direction opposite to the respective direction of rotation of the pedal. The device is movable between an open, in-use configuration, where the pedal is disposed in the neutral position to receive a foot and spaced away from the base, and a closed configuration, where the pedal is adjacent the base.

A seated exercise device comprising a body portion having a continuous side wall and a support surface, wherein the support surface is sized and shaped to receive a foot of a user; a grip portion attached to the support surface, wherein the grip portion is constructed from a traction material providing traction to the foot during operation; and a reversible floor portion removably attached to the body portion via an attachment means, wherein the reversible floor portion includes a base member having a first side and a second side, wherein the first side includes a first at least one floor slider and the second side includes a second at least one floor slider.

An exercise device with a crank housing supporting a pedal crank having a pair of opposing pedals that are pivotally mounted to the pedal crank. A first strut extends from the crank housing and is jointed to a second strut by a coupling that selectively allows the struts to rotate relative to each other so that the device may be folded into a planar configuration or extended for use. A cross-member is positioned at the end of each strut to form legs for supporting the pedal crank in an upright position. A tensioner is associated with the crank housing for selectively increasing and decreasing the force needed to turn the pedal crank. A telescoping arm may be used to interconnect the exercise device to a table or seat so that it can be folded and stored under the table or seat, and unstowed and unfolded for easy use.

An exercise device with a crank housing supporting a pedal crank having a pair of opposing pedals that are pivotally mounted to the pedal crank. A pair of struts extends from the crank housing and one of the struts has a hinge that allows the leg to fold inward into a collapsed configuration or extend and lock into place for use of the pedal crank. A cross-member is positioned at the end of each strut to form legs for supporting the pedal crank in an upright position. A strap may be coupled to one of the pair of legs for additionally securing the exercise device to an airline seat. A tensioner is associated with the crank housing for selectively increasing and decreasing the force needed to turn the pedal crank.

A device for passive therapeutic exercise comprises at least one pedal for supporting a foot during a swivelling motion of the foot, the pedal being pivotally mounted on a shaft, the pedal arranged on a side of a drive housing on a revolving shaft extending from the side wall of the drive housing, the revolving shaft coupled with a drive mechanism arranged in the drive housing to create a forced swinging movement of the pedal around an axis of the shaft, whereas the axis of swinging movement of the pedal is arranged under the pedal adjacent to the perpendicular projection of the ankle joint to the pedal, whereas the drive housing may be provided with outriggers to adjust the inclination of the drive housing towards the base, and a mechanism to switch operations on and off, and regulate the size of range and speed of the pedal swinging movement.

A portable exercise device includes a first body and a second body. The exercise device also includes a support structure pivotably connecting the first and second bodies. The support structure is configured to move between an engaged position and a disengaged position. The device also includes a resistance mechanism configured to resist movement of the first and second bodies toward one another when the support structure is in the engaged position. When the support structure is in the engaged position, the first body is positioned substantially parallel to the second body such that in a first open, in-use configuration of the device, the first body has a first neutral position relative to a pivot axis and in a second open, in-use configuration of the device, the second body has a second neutral position relative to the pivot axis.
