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.

An apparatus and method for gait training is disclosed. The apparatus includes a support structure having a base and at least one moveable platform connected to the base of the support structure, the at least one moveable platform having a top surface and a bottom surface. The apparatus further includes a drive system configured to control the movement of the at least one moveable platform. The drive system includes an actuator secured to the at least one moveable platform. A set of rollers is secured to the base and in contact with the at least one moveable platform. The set of rollers is configured to restrict movement of the at least one moveable platform to a one-dimensional axis. The apparatus further includes a first sensor located above the support structure. The first sensor is configured to determine an amount of downward pressure exerted on the training apparatus by a user. A second sensor is located above the support structure which is configured to determine the position of the user on the at least one moveable platform. The apparatus also includes a control system having a programmable logic controller (PLC). The PLC is configured to control the drive system and to receive data from the first and second sensors. In response to data received from the first and second sensors, the actuator changes the movement of the moveable platform.

Systems and methods for rehabilitation of limb motion are described herein. An example system can include a thermal imaging device for imaging a subject or a plurality of sensors for sensing force or pressure exerted by a portion of the subject's body. The system can also include a processor and a memory operably coupled to the processor. The processor can be configured to receive force or pressure data measured by the sensors or image data captured by the thermal imaging device, and calculate a quantitative measure of the subject's limb motion based on the force or pressure data or the image data.

A snowboard trainer (SBT) includes an SBT platform, a slide rail, slide supports, a central stand, and a front interface. The slide rail extends from a first end to a second end. The slide supports connect the slide rail to the SBT platform. The slide supports are configured to support the slide rail relative to the SBT platform. The central stand is positioned relative to the slide rail on the SBT platform and positioned between the first end and the second end of the slide rail. The central board receiver is connected to the central stand. The front interface is configured to be secured to a front portion of a snowboard. The front interface includes a roller bearing sized to be retained in the central board receiver such that when the roller bearing is received in the central board receiver, the front interface three-dimensionally rotates relative to the central stand.

Disclosed herein is an exercise apparatus comprising a conveyor mechanism comprising a continuous track and a plurality of bars movable along the continuous track in a closed loop path. The plurality of bars extend lengthwise in a lateral direction across a width of the conveyor mechanism. The conveyor mechanism has a front side and a back side, opposite the front side. The plurality of bars move in a downward direction along the front side of the conveyor mechanism and in an upward direction along the back side of the conveyor mechanism. The upward direction and the downward direction are perpendicular to the lateral direction. The conveyor mechanism also comprises a plurality of carriage components movable along the plurality of bars in the lateral direction. The conveyor mechanism additionally comprises at least one hold coupled to each carriage component of the plurality of carriage components.

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 body weight support system includes a tether configured to be coupled to an attachment device worn by a user to couple the user to the body weight support system. A method of providing gait training includes defining a reference length of the tether when the attachment device is in an initial position and defining a threshold length of the tether. A first amount of body weight support is provided during the gait training as the user moves relative to a surface and the length of the tether is less than the threshold length. A second amount of body weight support is provided during the gait training as the user moves relative to the surface and the length of the tether is greater than the threshold length. The method further includes displaying data associated with the gait training on a display of an electronic device.

A body weight support system includes a trolley, a powered conductor operatively coupled to a power supply, and a patient attachment mechanism. The trolley can include a drive system, a control system, and a patient support system. The drive system is movably coupled to a support rail. At least a portion of the control system is physically and electrically coupled to the powered conductor. The patient support mechanism is at least temporarily coupled to the patient attachment mechanism. The control system can control at least a portion of the patient support mechanism based at least in part on a force applied to the patient attachment mechanism.

A portable rehab station, including left and right outriggers, each having a forward end and a rearward end, the left and right outriggers being pivotally connected at the bottom ends of the respective left and right frame members to pivot between retracted and expanded positions, the retracted position including the left and right outriggers being generally mutually parallel, and the expanded position including the left and right outriggers being spread out at an angle of between about six and ten degrees relative to each other; a front, ground-engageable caster connected to the forward end of each of the left and right outriggers and a rear, ground-engageable caster connected to the rearward end of each of the left and right outriggers; and an actuator assembly connected with the frame and operably connected with the left and right outriggers to selectively pivot the left and right outriggers between the retracted and expanded positions.
