Abstract: The upper extremity exercise apparatus is a device intended to be used by humans to exercise their upper extremity. The apparatus exercises the upper limb in multiple planes in gravity assisted, gravity eliminated, and against gravity positions. It can be used in a standing, sitting, or lying position. The exercise apparatus consists of a long tubular structure generally made from plastic. A short movable sleeve, generally made from plastic, surrounds the long tubular structure. The movable sleeve has a slightly bigger inner diameter than the tubular structure's outer diameter. The difference in size allows the movable sleeve to migrate freely along the length of the apparatus. To operate the apparatus, the user positions his or her hand onto the movable sleeve. One hand stabilizes the apparatus while the other hand smoothly moves the sleeve in multiple planes.

Abstract: A precessional gyroscopic exercise device includes a housing containing a tiltable rotor assembly. The housing and the rotor assembly may be coupled together by a tilt assembly that defines a fixed precession axis for the rotor assembly and allows the rotor assembly to be tilted relative to the fixed precession axis. When the rotor is spinning, and the rotor assembly is tilted contact between the spinning axle and the interior surfaces of a circumferential channel in the housing causes the rotor assembly to rotate about the fixed precession axis, producing a gyroscopic precessional torque—this torque, and resultant wobbling of the device, is opposed by the user for the exercise effect. The tilting mechanism may be associated with handles on the outside of the device, allowing the user to selectively control the tilting of the rotor assembly. The handles may be rotatably coupled to the device, permitting operation of the device using a pedaling motion.

The elastomer is held with the bottom portion nested in the bottom of the palm of the hand and with the top portion gripped by the four fingers of the hand. As the fingers squeeze the elastomer, the top portion of the elastomer rolls or twists while the bottom portion of the elastomer remains stationary in the palm of the hand. The twisting of the top portion causes the elastomer to bow or arch into the hand, supporting the hand and generating a comfortable sensation in the hand while the elastomer is compressed with the fingers.

Abstract: A cyclonic rotor is a arm muscle trainer, comprising a semicircular shield and a rolling ball, where the round shield is composed of an outer shield and inner shield. These two shields are superposed and expanded conically downward with a larger space at the bottom to contain a rolling ball. In the interior of the semicircular shields, there are two lock ears to be inserted into the T-type channel on the handle. The lock ears and the handle are fastened firmly together by two outer screws which come from the exterior of the semicircular shields. While holding the handle, waving the rotor, the ball rolls within the hollow space. If waving slowly, the ball rolls slowly; if waving fiercely, the ball rolls fast and violently and continues self-rolling with centrifugal and inertia force and effects vigorous training on arm muscle.

Abstract: Fingers clenched during sleep (the ‘trigger finger’ condition) can be prevented from locking up by limiting the degree of flexure (closure) that the fingers can experience. An object of compressible resilient material, which may be a soft rubber ball, is affixed proximate the palm of the hand. As the fingers curve to become flexed they wrap around the object and the degree of flexure is limited to a non-locking amount by the gradual but increasing resistance of the object to compression. To keep the ball in place during sleep the person may wear a glove, and the ball is removably affixed to the exterior palm portion of the glove, perhaps with hook and loop fasteners. The glove may be of thin stretchable material that is also breathable and having finger sections that omit the ends thereof. The appliance can be used for hand exercises, and different degrees of effort can be obtained by selecting a compressible resilient object having a desired degree of resistance to compression.
