The invention relates to an exercise disc for strengthening the fingers of the hand, including a disc body with an upper disc surface on which the palm together with the fingers and the thumb can be placed, wherein receiving areas for a region of the fingertips and a region of the thumb tip are recessed in the upper disc surface. According to the invention: one disc body is provided for the left hand and one disc body is provided for the right hand; two neighbouring receiving areas are provided for each said region of the finger tips and said region of the thumb tip; and the respective finger and the thumb can move between the two receiving areas by abduction/adduction. Preferably, the receiving areas are in the form of blind slotted holes.

The invention provides an apparatus (10) adapted to teach wrist position of a non-bowing arm (2, 3, 4, 5, 6) in a pupil playing a stringed instrument, and a method of monitoring correct wrist position. The apparatus (10) comprises a non-contact proximity sensor (22), a proximity information transmitter (23); related circuitry (20), a power source (21) and, in one embodiment, a housing (11, 12). The housing is attachable to the stringed instrument in an operating position; and the non-contact proximity sensor (22) is positioned so that when the housing (11, 12) is in the operating position, the non-contact proximity sensor (22) is sensitive at least to when an inner part (8) of the wrist or hand of the pupil comes closer to the non-contact proximity sensor than a threshold distance (D) associated with misalignment of the hand (2) and forearm (3) of the pupil.

A physical therapy system that includes an apparatus coupled with a plurality of techniques of use thereof. The physical therapy system includes an apparatus having a body that is manufactured from a plurality of segments. The segments comprising the body are slidably coupled and configured to telescopically move so as to provide a collapsed position and an extended position with further providing of intermediate positions. The body of the physical therapy apparatus has a bottom end and a top end wherein the body has a narrowing diameter from the bottom end to the top end. The physical therapy system further includes preferred techniques of use that include but are not limited to picking up the apparatus, walking around the apparatus, disassembly and reassembly of the system, walking to a plurality of apparatus and reaching for the apparatus. Further techniques include placing a foot on top of the apparatus.

Universal Finger Blinds: a bottomless, adjustable, portable covering for the hands and fingers purposed to obstruct the hands and fingers from view to operate and develop necessary skills for muscle memory to manipulate equipment including but not limited to: keyboards, typewriters, computing and calculating devices or for various dexterity skills that require obstructed vision of the hands and fingers. One may desire to look at the fingers to assure proper placement. Instead the goal should be avoid looking at the hands and fingers, yet achieve proper finger placement. The present invention results with a hand and finger covering that stays in place while in use, covers the hand surface without clashing the left and right hands, and fits comfortably to the user's wrist. Such use will allow a proprioceptive occurrence leaving the eyes to focus on written material while hands and fingers achieve muscle memory resulting with proper finger placement.

An AR-based supplementary teaching system for guzheng and method thereof, the system includes an AR device, a data processing device and positioning devices for key positions, the data processing device is signal-connected to the AR device, and the positioning devices is installed on the guzheng code of guzheng, the positioning devices corresponds to the guzheng code of guzheng one by one; the AR device is used to obtain real scene data; the data processing device is used to guzheng and the positioning devices identify and generate string distribution data; also used to obtain operation instruction based on user actions, execute the operation instruction and generate virtual data; the AR device is also used to convert all data based on the string distribution data The virtual data and the real scene data are superimposed and displayed.

This invention allows a person to train a strumming and picking with a small compact device usable in situations where a guitar is not practical. Multiple string features are attached to a base feature and spaced to allow a user's fingers or plectrum to engage and release in a manner similar with a guitar or stringed instrument. Device is a simplified interface to avoid mechanically tuned strings and allow practice of rhythm techniques.

A user connection feature allows the device to be held relative to the user.

A training device for acquiring or maintaining muscle memory and fingertip callouses of a stringed instrument player. The device includes an elongated base plate structure having a width dimension like that of a neck of a stringed instrument and a length dimension configured to accommodate a plurality of fret-like lateral spaced protrusions extending above a top surface of the base plate. First and second sets of string supports are arranged respectively at the longitudinal ends of the base plate and arranged to hold device strings in tension above the top surface. An attachment structure may be provided for attaching the device to the person of the player in a ready-to-use position. The device is configured so that the player can strum the device strings to develop or maintain muscle memory and/or fingertip callouses.
