Hand held weight units of light weight manufactured as a solid unit, a shell unit with core insert combinations or modular units with interlocking ends. Shell units with core inserts and modular interlocking units allow for the changing of held weight by inserting or removing inserts or by locking or unlocking of modular weight unit sets creating varying held weight. The weight units are primarily used with upper body exercises during aerobic exercises in the home, outdoors, or in a gym setting such as walking or running to vary the intensity of workout during use.

A rehabilitation feedback system is used during rehabilitation of one or more body appendages of a user. The system includes four finger tracking elements and a thumb tracking element supported for movement relative to one another so as to allow a user to perform a gripping motion when the elements are coupled to the fingers and thumb of a user. A biasing member provides a resistance force acting to urge each tracking element towards a starting position thereof. A visual barrier is adapted to hide the hand of the user at a first side of the visual barrier from direct visual sight by the user at a second side of the visual barrier. A sensor at the first side of the visual barrier detects movements of the tracking elements and communicates with an indicator element detectable by the user from a second side of the visual barrier.

When an operation block is placed in a placing groove to electrically connect a connection module of the operation block to a control module that correspond in position to the placing groove, the control module sends an identification information of the operation block to a head-mounted display. The head-mounted display identifies the operation block according to the identification information thereof, and displays an augmented reality image corresponding to the operation block.

A prosthetic component suitable for long-term implantation is provided. The prosthetic component measures a parameter of the muscular-skeletal system is disclosed. The prosthetic component comprises a first structure having at least one support surface, a second structure having at least one feature configured to couple to bone, and at least one sensor. The prosthetic component is a housing for the at least one sensor and electronic circuitry. The electronic circuitry is hermetically sealed from an external environment. The at least one sensor couples to the support surface of the first structure. The support surface of the first structure is compliant. The first and second structure are coupled together housing the at least one sensor and electronic circuitry.

This exercise assisting device (1) is provided with a grip member (3) that can be gripped by a hand and that extends in a tubular shape or in a columnar shape. The grip member (3) has a recessed part (31) configured so that, when the device is gripped by the hand, only a portion at which the middle finger is placed is recessed.

A motor skill activity book for individuals having poor fine motor skills can be configured to be laid flat in an elongated fashion and to be closed into a compact rectangular prismatic form. Panels of the motor skill activity book can each include a face layer defining a cutout section, a backing layer, and at least one intermediate layer stacked between the face layer and the backing layer. The panels can be coupled via bindings such that the motor skill activity book can be configured between an open state in which the panels can lay flat such that the front face of each of the panels is substantially flush with the front faces of the other of the panels, and a closed state in which the panels stack on top of each other.
