The embodiments herein provide a portable hamstring stretcher for stretching hamstring muscles and inner thigh muscles. The portable hamstring stretcher comprises a primary board, a secondary board (leg pieces), a plurality of hinges, a chain, a plurality of ratchet straps, a ratchet, a plurality of hinges, and a plurality of adjustable straps. A user lies down on the primary board and wraps his legs using the adjustable straps on the secondary board to exercise the hamstring muscles.

A method is disclosed for using an artificial intelligence engine to modify resistance of pedals of an exercise device. The method includes generating, by the artificial intelligence engine, a machine learning model trained to receive measurements as input, and outputting, based on the measurements, a control instruction that causes the exercise device to modify, independently from each other, the resistance of the pedals. While a user performs an exercise using the exercise device, the method includes receiving the measurements from sensors associated with the pedals. The method includes determining, based on the measurements, a quantifiable or qualitative modification to the resistance provided by a pedal of the pedals. The resistance provided by another pedal of the pedals is not modified. The method includes transmitting the control instruction to the exercise device to cause the resistance provided by the pedal to be modified.

Portable devices and methods for preventing deep vein thrombosis (DVT) by assuring that the ankle is flexed and extended sufficiently to promote blood flow in the lower leg are disclosed. The device includes an actuator with a free movement mode that allows a patient to move freely between activations or to initiate movement to delay a next automatic activation.

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.

An ankle exerciser for exercising a user's ankles and includes a base, two pedals and two rotary units. The pedals and the rotary units are installed to the base. The rotary units are located between the base and the pedals so as to allow the pedals to be pivoted in multiple directions so as to stretch the ankles, and to keep ankles healthy.

The device is a foot power apparatus which provides a means for therapeutically strengthening the foot using an expansion spring mounted pedal suspended within a support frame assembly. One embodiment of the apparatus comprises which base, which generally resembles the sole of a shoe, and a support frame assembly which is attached at the front end and along the sides of said base. Suspended above the base within the frame assembly by a pair of opposing springs is a pedal transversely positioned to the base. With the user's foot positioned on the base, the front of the foot applies downward pressure to expand the springs while the heel of the foot remains stationary. Removable and interchangeable expansion springs provide customized and more accurate biomechanical motion for the needs of the particular patient. This system allows for the proper flexion biomechanics on an individual basis because of its ability to shorten the foot during the flexion process.

Exemplary embodiments of a portable exercise apparatus are provided, the exercise apparatus including a base, a bottom plate secured to a top portion of the base, a bracket affixed to the bottom plate, a base plate secured to a top portion of the bottom plate, the base plate including a plurality of holes on a top surface of the base plate, a foot plate secured to a top portion of the base plate and configured to selectively engage with at least one of the plurality of holes on the top surface of the base plate, such that when the foot plate is rotated the base plate and bottom plate also rotate, a threaded hole on the base, and a first resistance element having a first end secured to the threaded hole on the base and a second end secured to the bottom plate.

An isokinetic rotational exercise device provides for training and collection of information of a knee joint as it rotates. The isokinetic rotational exercise device includes vertical supports attached to a base frame that provides for an inclusion of rotational foot plates. The rotational foot plates are connected to cables of a pulley system that allows for an ability to add resistance of free weights and resistance tubing. Bottoms of the rotational foot plates include sensors to measure rotational degree, and the corresponding information is sent to a processor for display on a monitor on the isokinetic rotational exercise device or to an external device. A degree of force used to turn the rotational foot plates when the resistance is added is data collectable through force sensors in the cables of the pulley system.

An ankle exercise device comprises a base frame, a heel rest, a rotational component, and a plurality of resistance bands. The resistance bands may be connected to the rotational component. The rotational component rotates 90 degrees to orient the resistance bands in either a horizontal or vertical direction. The heel rest may comprise a u-shaped cutout to cup a user's heel. The heel rest is adjustable to align the heads of a user's metatarsals between the resistance bands. With the resistance bands in the horizontal direction, the user may rotate the ankle in the plantarflexion and dorsiflexion directions. With the resistance bands in the vertical direction, the user may rotate the ankle in the inversion and eversion directions.

A combined treatment, exercise, and traction apparatus including a base coupled to a plurality of linkages, a support frame having a first end and opposing second end and pivotally coupled to the plurality of linkages, the support frame formed to pivot between a first orientation and a different second orientation, a treatment table having a first end and an opposing second end, the treatment table slidably mounted to the support frame, and a plurality of actuators coupled between the base and the plurality of linkages, wherein the treatment table slides between a first position and a second position along a plane of the support frame when a first actuator is activated.
