Abstract: A device and method for providing physical, occupational, or cognitive therapy to patients which employs video game software manipulated by a game controller and running on a central processing unit such as a computer or video game console. The device and method take advantage of the wide familiarity of patients with the manipulation of game controllers to operate widely sold and popular video games to provide immediate familiarity with the system operation. An interface and software are employed along with body engageable movement tracking components to change the required controller manipulations by the user in the game, to elicit movements predetermined to provide the therapy for the user.

Abstract: A regulating component to regulate fluid flow through the axial passage communicating between the intake end, and mouth engageable distal end, of a drinking straw. The component has an upper wall separated from a lower wall by an engaged sidewall all defining a restriction chamber. When engaged in the axial passage of a drinking straw, fluid traversing the straw all traverses through apertures in the lower and upper wall and thereby through the restriction chamber. Force of the moving fluid on a ball in the restriction chamber acts to raise the ball to seal the aperture in the upper wall. If the fluid reaches too high a speed or continues long enough at a lower speed to move the ball upward it seals the restriction chamber from the exit end of the straw.
