Abstract: The present disclosure is directed to an exercise device that makes push-ups more physically challenging by reducing the area of contact that the push-up device makes with a surface while in use. A distal end of the device has a minimal radius of curvature, such that the surface area of the device in contact with the ground is minimized, thereby inducing instability. The user is challenged to overcome the inherent instability of the push-up device, thereby recruiting more muscle groups, placing higher demand on involved muscle groups, and practicing balance and proprioception. Additionally, by elevating the user's hands above the ground, the device can also enable the user's chest to move below the plane of the palms of his or her hands, thus inducing a larger range of motion with each push-up and further challenging the user's muscles.

Abstract: A striking bag features a resiliently flexible foam tube, and a striking surface that is connected to an end of the flexible tube to hang therefrom in an exposed position strikeable from below. A threaded rod projects from an upper end of the flexible tube for coupling with a surface mount that is fastened to a ceiling or other suitable overhead surface. The surface mount features a rigid portion into which the threaded rod is threaded. The foam of the tube and the threaded rod solely define a resiliency by which the tube flexes and returns to a normal straight position relative to the ceiling mount. A fabric loop at a bottom of the striking surface allows selective connection of a stretchable tether between the striking surface and a ground based tether point to change a responsive character of the striking bag and enable two distinctive modes of use.

Abstract: The system and method disclosed herein prevent a patient from interrupting the vacuum created by the vacuum line attached to the saliva ejector so that suction continues to be present even if the patient clamps his or her lips tightly about the shaft of the saliva ejector.

Abstract: A system for extending a finger of a hand comprises structural elements configured to be inserted into a flexed finger and capable of providing a controllable force to extend the finger. In some embodiments, structural elements comprise a cam connected to a spacer, the spacer connected to a first strut, and a second strut holding a loading assembly, an end piece and a spring. The loading assembly compresses or relaxes the spring, which exerts a variable force on the end piece, which rotates the cam and the first strut about an extension angle. When the extension angle is minimal, the first and second struts are substantially parallel. A method of extending a finger of a hand substantially fixed in a flexed position comprises inserting a system comprising structural elements into the finger and thereafter providing a force to extend the finger and maintaining the force for a period of time.
