An apparatus for natural torso and limbs tracking and feedback for electronic interaction with fall safety support. The apparatus comprises a body harness worn on the body of a user, a support structure designed to bear the weight of the user in the event of a stumble, trip, or fall, and a plurality of tethers attached at one end to the harness and at the other end to the support structure. One or more sensors are integrated into the system to measure aspects of the user's movement and used as input to control a computer system. In the event of stumble, trip, or fall, all of, or a portion of, the user's body weight is borne by the tethers as a safety mechanism to prevent injury. The system is designed to be used with virtual reality systems wherein the user's vision is blocked or obscured by a virtual reality visor.

Methods and systems for controlling a force generator of an exercise apparatus are described wherein the method comprises determining or receiving angular positions of a rotatable axle of an exercise apparatus when a force is applied to a force receiving structure of the exercise apparatus, the rotatable axle being part of a mechanical power transmission system connecting the force receiving structure via the rotatable axis to a force generator which is controlled by a computer based on a kinematic model, the kinetic model representing equations of motion of the exercise the apparatus; determining or retrieving first geometrical scaling values associated with the angular positions and incorporating the first geometrical scaling values into the kinematic model to form a first modified kinematic model, the first geometrical scaling values being associated with a non- circular gear of a first predetermined non-circular geometry; and, determining applied force values for the angular positions, each applied force value representing a force that is applied to the force receiving structure; and, controlling the force generator based on first resistive force values to mimic an exercise apparatus comprising a mechanical power transmission system including the first non-circular gear, the first resistive force values being computed using the first modified kinematic model and the applied force values.

An exercise device has a frame supporting guide links to which foot support links are pivotally attached. Upper pulleys are pivotally connected to the frame. Lower pulleys are connected to the foot support links. A vertical drive assembly is coupled to the foot support links by flexible elements. The flexible elements extend from the vertical drive assembly, about an upper pulley, about a lower pulley and to a second end connected to the frame.

In various embodiments, provided herein are systems, methods, processes, and devices for providing locomotive rehabilitation to a subject via one or more gait motions that substantially accurately mimic motions performed in healthy, natural gait cycles. The system may mimic natural gait motions via footplates and handles, and one or more linkage systems. In particular embodiments, the system may further include a motor unit and/or clutch for providing controlled forces assisting or resisting motions of a linkage system. Further, the system may include a tower for operating in a standing or seated position. In at least one embodiment, the system includes a body weight support system that provides offloading forces to a subject.

A system and method provides real-time coaching and adjustment to training. A wearable device may be configured for over-the-ear wear, which includes a speaker, a transceiver, and sensors to measure biometric activity in the user while worn during athletic performance training. The system uses a method which compares past performance to current performance and training goals to adjust a training plan during performance for maximizing training results. The system analyzes current and past performance and generates new training performance output goals in real-time based on the user's current performance. The system then transmits coaching output during a live training session instructing the user on how to adjust their performance output during a current training session. Some embodiments include connecting to smart gym apparatus which connect to the system and automatically increase/decrease resistance/speed depending on the system determining a need to change performance output for maximum gains.

An exercise apparatus orienting foot pedals and handlebars having first and second rotating armatures for generating subtended paths of rotation, with motors to revolve the first and second rotating armatures in opposite directions and allowing the subtended paths to migrate from a first two-dimensional plane into a second two dimensional plane and back into the first two-dimensional plane.

Systems and methods for management and scheduling of differential air pressure (DAP) and other unweighted or assisted treatment systems are provided. The methods and systems can include generation of a suggested workout based on matching user data to data of other users sharing similar characteristics using an aggregate database of user information and related workout information. The methods and systems can include matching a user to an available and/or appropriate DAP system. Also provided are methods and systems including performing a workout and uploading performance information to an aggregate database of user information.

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 resistance mechanism for an exercising device is provided. In one embodiment, the resistance mechanism comprises at least one flywheel. The resistance mechanism may also comprise at least one resistance index wedge configured to engage with the at least one flywheel. The resistance mechanism may also comprise a resistance adjustment mechanism connected to the resistance index wedge and configured to alter a resistance provided to the exercise device by increasing pressure provided by the at least one resistance index wedge to the at least one fly wheel assembly, wherein the resistance mechanism is configured to operate in an outdoor environment.
