An apparatus for foot exercise for strengthening at least the ankle and muscles around the ankle. The apparatus includes a housing having a cutout in a top wall thereof for allowing a foot of a user to pass through. A sleeve of a socks shape, hangs from the cutout, and the sleeve can receive at least the foot up to the ankle of the user. Multiple inflatable bags are disposed within the housing and around the sleeve, such that the inflatable bags, when inflated, resist movement of the foot received within the sleeve. The user can insert the foot into the sleeve; upon inserting the foot, inflates the plurality of inflatable bags; and upon inflating, moves the foot against the resistance offered by the inflated plurality of inflatable bags.

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.

A piece of fitness equipment comprises a carrier for carrying a pump on a body part of a person. The carrier comprises a main body having a first end and a second end, a fastener capable of connecting the first end and the second end with each other, and a holder for detachably attaching the pump to the main body.

A differential air pressure system has a pressure bag with windows and preferred folding configuration such that when the bag is folded no window is folded. The pressure bag is supported by a lift support that is proximal to a user control panel and adjacent to or nearly adjacent to the user who is coupled to the pressure bag. A treadmill base for use with differential air pressure equipment is provided. There are various improvements provided to adapt the operations of the DAP system via the use of separate pressure volume and non-pressure volume portions of the treadmill base. Various improvements to serviceability and repairs are provided by placement of components outside of the pressure volume portion or by providing one or more pressure volume access points.

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 belt for use in a BFR system with an outer belt material hermetically sealed to an inner belt material along a perimeter, thereby forming at least one inflatable chamber, the inflatable chamber having an input port for accepting a gas into the chamber, the belt further comprising a first fastening means in communication with the outer belt material, for attaching to a second fastening means in communication with the outer belt material, thereby locking a circumference of the belt, when wrapped around a user's limb, and the belt further comprising a pre-tensioning system for prescribing and applying a known amount of initial compression to the limb by the belt.

Described herein are various embodiments of differential air pressure systems and components for differential air pressure systems. The air pressure systems comprise a chamber for receiving at least a portion of a user's body. Pressure in the chamber can be changed to adjust force on the user's body. Described herein are various methods and related structures for sealing a user into a pressurizable chamber. Also described herein are various methods and related structures for changing the shape and/or height of the chamber. Described herein are various types and configurations of chambers and support structures for chambers. Also described herein are various methods and related systems for treating various conditions using the differential air pressure systems, including but not limited to obesity, cardiac disease, multiple sclerosis, cerebral palsy, or Down Syndrome.
