Abstract: A training device for acquiring the correct hand motion associated with the different types of sport and for strengthening the wrist and forearm. The device is simple and portable. It utilizes a combination of a magnet and a plunger, the magnet having a sufficient force to keep the plunger attached but not strong enough to prevent the plunger from dislodging from the magnet when a user snaps the device. The device is designed so that the snapping sound caused by the plunger hitting a wall synchronizes with the impact on the muscles felt by the user during a hand motion.

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.
