A DAP unweighting system for unweighting a user while using an exercise machine is provided that includes an unweighting assembly having a substantially airtight chamber formed about at least a portion of the exercise machine that includes a user seal for encapsulating a portion of the user, and at least one additional frame member for securing to the exercise machine frame element to secure the chamber to the exercise machine. The exercise machine can include a treadmill having a belt extending a belt length in a longitudinal direction of the unweighting system The at least one additional frame member can have a frame member length less than the belt length that can be oriented substantially parallel with the belt when securing the chamber to the treadmill.

There is described an integrated unweighted gait training system having an unweighting system comprising a computer controller; a gait measurement system in communication with the controller; and a display in communication with the computer controller adapted and configured to provide real-time feedback to a user of the integrated unweighting gait training system. The unweighting system may be a differential air pressure (DAP) unweighting system or a non-DAP unweighting system.

A method for controlling a DAP system is provided that includes calculating a user seal interface height based on an estimated user height, and based thereon determining an attachment carriage height and a usage carriage height different than the user seal interface height. The method also includes driving powered vertical lifts to raise each carriage to an attachment position at the attachment carriage height while the user is in the DAP system through the top opening including raising about the user the seal frame attached to the carriages and thereby raising the top opening attached to the seal frame, and also controlling the lifts to retain the attachment position during user seal attachment and confirming the attachment. Responsive to confirming, the method includes driving the lifts to move each carriage to a usage position at the usage carriage height and inflating the enclosure to an unweighting.

A height-adjustable DAP exercise system is provided having a support platform, an inflatable enclosure secured to the support platform at a base opening through the enclosure and extending vertically therefrom when inflated, and a top frame attached to the enclosure at an enclosure top opening. The DAP system further includes adjustable lift restraints each having a restraint length between first and second ends and configured for adjustment between a first restraint length and at least one second restraint length, in which each first end of each lift restraint is attached to a middle portion of the enclosure and each second end is attached to the top frame or the base. The enclosure height is adjustable between a first and second enclosure height responsive to adjustments for lift restraint lengths. The system also includes a low height safety harness for the top frame and related methods.

A device for performing blood flow restriction training during the day, integrated with a garment, and controllable to apply a desired compression level to a range of muscles with the intent on improving the health and fitness of a user doing normal daily activities.

A lung exercise apparatus and method with an enclosure, with an inside, an outside and an open top, configured to hold a liquid of a first density. An additive to the liquid that increases the first density such that a person in the liquid is more buoyant. Weight removably connectable with the person such that a person in the enclosure is held vertical in the enclosure and partially immersed in the liquid below a surface of the liquid and with some of a person's body above the surface of the liquid. And a harness that is removably connectable with the person to hold some of the person's body above the surface of the liquid where lungs in a person's body are below the surface of the liquid.

An inflatable unweighting enclosure for an exercise device is provided formed from a pair of opposing sheets attached to each other by a seam along a closed shape at their perimeter portions, each of which has a top region, an opposite base region, and central region. A trim path interrupts each articulated shape at the base region that defines a perimeter of a base opening for the enclosure when inflated, in which the base and base opening are substantially planar and the base perimeter defines an enclosure inlet. When inflated, the pair of flexible sheets expand laterally apart to define an enclosure inner space and form an elongate, disc-shaped structure interrupted by the base opening. The base opening attaches to a base support of the exercise device, which is shaped and sized to orient and support the enclosure vertically for providing unweighting to a user attached to a top opening.

Apparatus (1) for the physical training of at least one of the limbs (40) of a living being, comprising a cuff (2) comprising an inflatable pouch (3), a device (4) for inflating the pouch (3), a system (5) for venting the pouch (3), a control unit (9) controlling the inflation device (4), said inflatable pouch (3) and the cuff (2) surrounding the pouch (3) being able to be positioned around a limb (40) that is to be trained so as to make it possible, when the pouch (3) is in the inflated state, to reduce the blood circulation through said limb (40). The training apparatus (1) comprises an air reserve (6) connected to the pouch (3) for transfer of air between the pouch (3) and the air reserve (6) at least when the pouch is deformed, and a pressure sensor (7) configured to measure the pressure of the air circuit, at least part of which is formed by the fluidic connection (8) between the inflatable pouch (3) and the air reserve (6).

Described herein are various embodiments of differential air pressure systems and methods of using and calibration such systems for individuals with impaired mobility. The differential air pressure systems may include an access assist device configured to help a mobility impaired user to stand in a pressure chamber configured to apply a positive pressure on a portion of the user's body in the sealed pressure chamber. The system may also include load sensors configured to measure the user's weight exerted inside and outside the chamber. The system may be calibrated by determining a relationship between the actual weight of the user and the pressure in the chamber, where the actual weight of the user may be measured by more than one load sensor and at least one load sensor is not in the pressure chamber.

Described herein are various embodiments of differential air pressure systems and methods of using such systems. The differential air pressure system may comprise a chamber configured to receive a portion of a user's lower body and to create an air pressure differential upon the user's body. The differential air pressure system may further comprise a user seal that seal the pressure chamber to the user's body. The height of the user seal may be adjusted to accommodate users with various body heights.
