A multi-functional curved board to be used when working in standing position and for working when sitting down as a support for feet and generally for maintaining muscle strength, the multi-functional curved board having at least one curved body (1). The body (1) comprises at least one counter-curve means (3). One surface (1b) of the body is curved outwards and the counter-curve means are fastened to a surface (1a) opposite this surface (1a) adjacent the end sides (1d) of the body (1) and the counter-curve means are curved outwards from the opposite surface of the body (1).

A transformable balance board that may be alternately used as a balance board or wobble platform and a wheeled board or roller platform. The balance board includes a rigid platform preferably covered with a closed-cell yielding foam pad layer on top on which a user can support his or her weight. When used as a wobble platform, a relatively large central fulcrum member extends down from the rigid platform so that the board wobbles with no stable horizontal position. In a second usage configuration as a wheeled board or roller platform a plurality of sturdy wheels or rollers retracted into the underside of the rigid platform are extended vertically downward from their retracted positions. Because the vertical height of the wheels is greater than the vertical height of the fulcrum member below the rigid platform, the wheels make contact with the ground and the fulcrum is lifted up and out of contact with the floor below.

Height-adjustable apparatus using a spring to urge forward and rearward undulating whippy locomotion. A hand-crawling embodiment enables users to engage in all-fours crawling locomotion while the body is conventionally situated in a two-legged orientation. A foot-bounding embodiment enables walkers, joggers, runners and jumpers to engage in forward and backward whippy locomotion. A crutch embodiment enables crippled or injured users to likewise engage in whippy locomotion.

Balance training systems and methods are disclosed. A balance training system is disclosed, comprising: a lower member having a ground contacting surface and an upward facing surface; an upper member having a foot receiving surface and a downward facing surface; the upward facing surface and the downward facing surface being shaped for contact with each other; and the upper member having a balance position when a balance point on the upper member is in contact with the lower member. A balance training system is also disclosed comprising a first platform having a top surface (ground plane) which supports the user's weight, a support having flexible and/or compressible upward facing surface in contact with a downward facing surface of the first platform, the ground plane being within 0.5″ of the top surface of the flexible and/or compressible upward facing surface to reduce or prevent horizontal movement of the ground plane when the first platform changes angle. A balance training system is further disclosed, comprising a first platform having a top surface (ground plane) that supports the user's weight, a curved downward facing convex surface of the first platform, the top surface being aligned within ½″ of the downward facing curved surface.

A low-cost balance exerciser for use at work includes a central support for a ball joint disposed on a base, an inflatable elastic toroidal bladder disposed on the base and centered about the central support, a rigid circular balance platform whose center is fixed to the ball joint on its lower surface, and a pump connected to the inflatable elastic toroidal bladder.

A balance board system may comprise a platform, a pivot member, a first bodily engagement member, and a second bodily engagement member. The platform may include a planar body with upper and lower sides and that extends between a first end and a second end. The platform may have a central portion between the first and second ends. The pivot member may be located on the lower side and the central portion of the platform. The first bodily engagement member may be located on the upper side and adjacent the first end of the platform. The second bodily engagement member may be located on the upper side and adjacent the second end of the platform. The first and second bodily engagement members may be configured with respective incline angles relative to the platform.

The present invention provides an exercise machine comprising a base, a platform having an upper side adapted in use to support a user and an underside, a support column supporting the platform in a position spaced apart from the base wherein the platform is secured to the support column such that the platform can rotate about two perpendicular axes, and three or more means independently operable to move all or a part of the platform, wherein one or more of the means independently operable to move all or part of the platform is capable in use of adopting at least two positions relative to the platform.

Provided are methods that include presenting to a subject an embodied cognitive task that includes a cognitive component and a physical component. The methods further include assessing the subject's performance on each of the cognitive component and the physical component, and adapting the difficulty level of the embodied cognitive task based on the subject's performance on each of the cognitive component and the physical component. In certain aspects, the methods find use in enhancing cognition, physical fitness, or both, in a subject. Also provided are methods of treating and diagnosing cognitive disorders. Systems and computer readable media for practicing the methods of the present disclosure are also provided.

Bilateral vestibular loss is a chronic condition of which the causes can be ototoxic, infectious, traumatic, autoimmune or congenital. An object of the invention is to improve the effectiveness of a vibrotactile feedback arrangement. The current invention provides a vibrotactile feedback arrangement for use arranged to a human body, comprising: a sensor arranged for sensing a current attitude of the human body relative to the environment; tactile actuators arranged for allowing the human body to perceive an attitude deviation; an elongated carrier for holding the tactile actuators and the sensor in tactile communication with the human body and for holding the tactile actuators and the sensor substantially fixed relative to the human body; and a processing unit configured for: receiving the current attitude from the sensor; determining the attitude deviation based on comparing a desired attitude of the human body with the current attitude; and transmitting an actuation signal to one or more of the tactile actuators based on the attitude deviation; wherein the tactile actuators are arranged to the carrier such that, when the carrier is used, the tactile actuators are arranged substantially in a reference plane; wherein the reference plane is functionally perpendicular to a central axis of a torso of the human body and the reference plane intersects the torso to define a circumference, wherein the tactile actuators are arranged to the circumference; and wherein the carrier comprises stretchable material such that the relative distance between the tactile actuators and/or between the tactile actuators and the sensor is maintained independent of the length of the circumference.

A portable exercise device that allows a user to train the muscles in both the upper and lower body while offering a user to choose among varying amounts of resistance. The portable exercise device also allows a user to pack the entire exercise device into a compact unit that is convenient for transporting or traveling. The portable exercise device is composed of a platform, a hinged body, a base, rods, cables, and a series of handle assemblies to provide the user with the ability to perform a variety of exercises.
