A system includes a guidance device that provides feedback to a user to compress a patient's chest at a rate of between about 90 and 110 compressions per minute and at a depth of between about 4.5 centimeters to about 6 centimeters. The system includes a pressure regulation system having a pressure-responsive valve that is configured to be coupled to a patient's airway. The pressure-responsive valve is configured to remain closed during successive chest compressions in order to permit removal at least about 200 ml from the lungs in order to lower intracranial pressure to improve survival with favorable neurological function. The pressure-responsive valve is configured to remain closed until the negative pressure within the patient's airway reaches about −7 cm H.sub.2O, at which time the pressure-responsive valve is configured to open to provide respiratory gases to flow to the lungs through the pressure-responsive valve.

A mobility device configurable in a first walk configuration and a second stair-climb configuration, including a frame with movable front leg portions, a leg-actuation system connected to the front leg portions and a safety-control device mounted to the frame. The safety-control device includes a configuration selector, and a lever connected to the leg-actuation system and configured to actuate the cable actuation system so as to cause the first and second movable leg portions to move from a first position to a second position. The lever remains locked in a first lever position such that the lever cannot be moved unless the configuration selector is in a depressed position, thereby preventing inadvertent movement of the leg portion.

An exoskeleton wheelchair system includes a base, one or more wheels coupled to the base, a body support connected to the base comprising: a back support; and one or more leg supports pivotally coupled to the back support, and a gait wheel linked with the one or more leg supports via one or more gait linkages and configured to rotate the one or more leg supports. The one or more leg supports are configured to pivot about a first axis when the back support is in a standing position mode. The back support is maintained at a fixed position relative to a location of the base when the one or more leg supports pivot about the first axis while the back support is in the standing position mode.

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.

An example assistive ambulation system is described herein. The system includes a walker including a base frame, a walker frame attached to the base frame, a plurality of rolling members attached to the base frame, and a hoist attached to the walker. The base frame includes a pair of support members and a base cross member. Each of the support members extends between forward and rearward ends of the walker. Additionally, the pair of support members are spaced apart and substantially parallel to one another. The base cross member extends transversely between the pair of support members. The walker frame includes a pair of bent posts and a walker cross member. Each of the bent posts extends upward from the base frame. Additionally, the pair of bent posts are spaced apart and substantially parallel to one another. The walker cross member extends transversely between the pair of bent posts.

A treatment force application device preferably for use on biological tissue includes a proximal end having a weight and having a support for a practitioner; a distal end having a treatment interface configured for applying a therapeutic treatment including at least a treatment force; and a connection between the support and the treatment interface. The connection is lockably adjustable by the practitioner to establish a placement of the treatment interface relative to the support. The weight is sufficient to substantially prevent movement of the treatment interface relative to the support when the connection is locked. The support enables movement of the practitioner to provide a practitioner force, and the practitioner force is transferred from the support to the treatment interface through the connection. The support includes at least one flexible brace against which the practitioner can press to provide the practitioner force. The therapeutic treatment further includes at least one of heat, cold, moisture, vibration, pulsing, ultrasound, radiation, chemicals, and medicine. The treatment interface can be configured for obtaining biometric, treatment, physical, mechanical, force and environmental data related to use of the device.

An ankle joint device comprises a base, an angle adjusting assembly, and a foot support member; the angle adjusting assembly comprises a rotation member and an anti-rotation member, wherein the rotation member is rotationally mounted on the base, and the anti-rotation member is slidably and detachably locked to the rotation member along the axial direction defined by the rotation member; the foot support member is mounted to the anti-rotation member, after the anti-rotation member slides away from the rotation member in the axial direction by a predetermined distance, the foot support member is allowed to rotate at a predetermined angle, and the foot support member is locked to the rotation member to rotate with the rotation member relative to the base after the anti-rotation member slides close to the rotation member in the axial direction by a predetermined distance in a state of being maintained at the predetermined angle.

An ambulatory assist device provides mobility assistance for an ambulatory transition between seated and standing positions. A mobile frame defines a structure similar to a walker device. The mobile frame includes a plurality of wheels for rolling communication with a ground surface. Lift arms, driven by an actuator, pivot around an axis of a cross member attached to the frame. The lift arm is configured for actuated pivotal movement for an ambulatory transition between seated and standing positions by a harness engaging the patient. The pivot is based on an arc of patient movement between the sitting and standing positions, such that the arc emulates natural movements of a human skeletal frame during an ambulatory transition. The patient experiences forces along the same path that an unassisted transition would encounter. Once in an ambulatory position, the device allows ambulatory movement in a manner similar to a walking assist (walker) device.

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.
