Basal thumb joint implant has a head with a smooth, generally hemispherical, medio-proximally directed, articulating surface, and a generally abrupt, distally directed, truncation thereto; and a stem attached to the head, which arises from the truncation of the head and includes at least one of the following features:A) a general angle of attachment to the head which is acute in relation to the truncation of the head;B) a flanged cross-sectional stem profile;C) an inwardly curved stem;D) an eccentric head attachment site for the stem.The implant may be one-piece or modular in construction. The modular basal thumb joint implant, however, which is not necessarily limited by requiring inclusion of the aforesaid additional features A-D, includes a head with a smooth, generally hemispherical, medio-proximally directed, articulating surface, a generally abrupt, distally directed truncation thereto, and a stem trunion-receiving cup in the truncation; and a stem attachable to the head, which stem has intracarpal spike-like distal end, and a proximally directed trunion, which trunion is insertable into the stem trunion-receiving cup of the head. Other digits may be provided with analogous implants, particularly with respect to those digital implants amenable to modularity.

The robot anthropomorphic multi-fingered hand device relates to a mechanical finger device, which mainly includes a palm, a thumb, an index finger, a middle finger, a ring finger, a little finger, a joint body at the base of the thumb, and a joint body at the base of the four fingers. The index finger, middle finger, ring finger, and little finger all include root phalanx, middle underactuated joint, middle phalanx, terminal underactuated joint, and terminal phalanx, respectively. The index finger, middle finger, ring finger and little finger are respectively socketed on the same four-finger root joint body and connected with the palm. The base joint body of the thumb and the base joint body of the four fingers are active joints driven by motors, and the middle underactuated joints, end underactuated joints and thumb end underactuated joints of the index finger, middle finger, ring finger and little finger all adopt the same underactuated joint. Its appearance, size and movement are similar to human hands, with 11 degrees of freedom and high integration. It only needs 2 motors to drive, and the motor and its driver are hidden in the hand. It is easy to control and can stably grasp objects of different shapes and sizes. on anthropomorphic robots.

The at least one Button configured to accept a knuckle bump may be configured to be adjacent to a user's metacarpophalangeal index finger joint. The at least one Button configured to accept a knuckle bump may be configured to be adjacent to a user's metacarpophalangeal thumb joint. The Takeup Module (300) comprises a Motor Compartment (305), a Takeup Spool Compartment (310), a Takeup Spool Gear Compartment (315), a Takeup Film Window (320), a Motor (325), a Motor Gearbox (330), and at least one Takeup Spool Gear (340). The Takeup Module (300) may further comprise a Takeup Spool Window (350) configured to provide a view of a Takeup Spool (345) within the Takeup Module (300). Also disclosed is a Takeup Spool (500) comprising a Spool Alignment Tab Wheel (505), a Spool Ribbed Shaft (510), a Rib Quarter Section Cutout (515), a Spool Alignment Slot Wheel (525), a Spool Alignment Tab (530), a Spool Alignment Slot (535), a Plurality of Wheel Cutouts (540), and a Plurality of Wheel Slots (545). Also disclosed is a method for maintaining clear vision with goggles comprising receiving a command input via a knuckle bump, transmitting a designated signal to a module comprising a Motor and a Takeup Spool, activating the Motor to cause the Takeup Spool to rotate, and winding a Transparent Film a designated distance over goggles.

A thumb function rehabilitation exoskeleton robot relates to exoskeleton robots. The thumb function rehabilitation exoskeleton robot solves the problem that existing rehabilitation mechanical arm cannot thoroughly simulate natural motions of finger joints, is poor in rehabilitation treatment effects and lacks a sensing function. According to the thumb function rehabilitation exoskeleton robot, an interphalangeal joint unit and a metacarpophalangeal joint unit drive thumb joints and metacarpophalangeal joints to bend or stretch through flat guide rod mechanisms; a thumb carpal joint unit is centered to the carpal joint of a thumb directly through a metacarpal adjustment mechanism to achieve contracting or extending motions of the carpal joint; a transmission driving mechanism is powered by a direct current motor; a cable reel module transfers the moment output by the direct current motor to the interphalangeal joint unit, the metacarpophalangeal unit and the carpal joint unit through Bowden cables. The thumb function rehabilitation exoskeleton robot is applicable thumb function rehabilitation.

Disclosed is a method and a device for practicing a tennis serve, learning how to perform a tennis serve, and for teaching a student how to perform a tennis serve. The method includes placing an indicator band on the server's thumb joint, placing a positioning indicator on the throat of the server's racquet, standing at the baseline in a serving position, bringing the racquet to the tossing hand and physically touching the positioning band on the thumb with the indicator band on the racquet, dropping both hands together, one hand holding the ball and one hand holding the racquet, then extending the throwing hand skyward and releasing the ball with the palm of the hand up, and bringing the racquet around and striking the ball at the apogee of its arc.

A multi-purpose glove includes protective or shock absorbing padding over the pulleys and tendons of the boney prominences of the fingers and thumb between adjacent joints of the boney prominences or phalanxes. The center axis of rotation of the individual joints are provided with expandable material positioned to overlie specific finger and thumb joints thereby defining motion or flexion zones at these joints.
