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 dorsiflexion (or eversion) assistance device attaches around an ankle and foot, such us over footwear. A tensioned cord is extended between a portion attached to the ankle and a portion attached to the foot. This tensioned cord is attached to one of a plurality of portals of a connector attached to the ankle and connector attached to the superior side of the foot depending on a need for greater assistance on a left, medial, or right side. The connector on the ankle can be a bearing movable or rotatable front/back, left/right and around so as to allow the tensioned cord to move as the wearer walks as well as angle the tensioned cord in a resting or walking state.

A shaped standing mat or base providing a trampoline-like rebounding surface that is a highly responsive and dynamic support surface for a standing person where that person is able to maintain a proper stance relative to their foot angle, and to engage in mild exercise movement and foot rotation and stretching without undue interruption of mental concentration in a work or other environment.

A device for assisting a wearer in rotationally moving an ankle joint. A drive mechanism coaxially rotates with the ankle joint using a drive motor; a control device controls the drive motor. A storage stores a basic movement pattern and a corrected movement pattern that represent time-series changes in ankle joint angle in a gait cycled. A calculator obtains the corrected movement pattern by correcting the basic movement pattern based on input operation. The basic movement pattern is represented by a polygonal line or a Bézier curve, each of which includes a plurality of predetermined points serving as inflection points, or a combination of thereof. The calculator generates the corrected movement pattern corrected by adjusting positions of the plurality of predetermined points on the basic movement pattern, and, based on the corrected movement pattern, the control device controls driving provided by the drive motor.

The training apparatus according to an embodiment includes: a support unit; a guide unit fixed on the support unit and including rails which extend in a front-rear direction; a sliding unit which is movable in the front-rear direction along the rails of the guide unit; a pillar-shaped rotation axis fixed on the support unit; a footrest unit which supports a user's foot; a lower support formed below the footrest unit; and a connection rotating unit formed below the footrest unit and connected to the rotation axis of the support unit through insertion to allow the footrest unit to rotate around the rotation axis. A plurality of springs installed inward from two sidewalls of the sliding unit is configured to come into contact with the lower support of the footrest unit and apply pressure from two sides when the footrest unit rotates.

Supination and pronation of an ankle joint during a lower limb exercise is achieved. A foot-pedaling exercise equipment as a lower limb exercise equipment is a lower limb exercise equipment that enables a lower limb exercise to be performed using a pair of pedal units. Each of pedal units includes: a step part on which a corresponding foot part can be put; a base part; and a joint part that is provided between the step part and the base part and couples the step part to the base part in such a way that the step part can do a pitch turn, a roll turn, and a yaw turn with respect to the base part.

An ankle box system includes at least one ankle box and a riser. Each of the ankle boxes has an upper surface and a lower surface, and a plurality of projections extending from the lower surface, such as at the ends thereof. The riser has a bottom surface and a plurality of riser levels, each of the riser levels configured for selectively receiving one of the projections of at least one of the ends of an ankle box, at least two of the riser levels having an upper surface being disposed at different elevations from a bottom surface of the riser. The upper surfaces of the ankle boxes have a shape configured to enhance exercising the human ankle.
