Some embodiments include an outer tube, a pivot structure, an inner tube, a rotational element, and a central rod. The pivot structure perpendicularly intersects the outer tube at a midpoint of the outer tube. The inner tube is coaxially within the outer tube. A first portion of the inner tube is within the outer tube on one side of the pivot structure. A second portion of the inner tube is within the outer tube on another side of the pivot structure. The rotational element couples to the pivot structure, rotates about an axis of the pivot structure, and interfaces with the first and second portions of the inner tube to cause rotation of one portion of the inner tube in a first rotational direction to counter-rotate the other portion of the inner tube in a second rotational direction. The central rod is within the inner tube and translates axially.

The present invention concerns the field of medical technology and relates to a device for the measurement, diagnosis, and/or therapy of the strength of the human finger, hand, arm, and/or shoulder, as can for example be used to measure bending strength. The object of the invention is to specify a device with which a multi-functional measurement, diagnosis, and/or therapy of the strength of the human finger, hand, arm, and/or shoulder is possible on one device. The object is attained by a device composed at least of a base plate and force-measuring sensors, of which at least one sensor comprises a puller bolt passing therethrough and this force-measuring sensor is positioned in a stationary manner on one side of the base plate and is connected to an actuation part in a force-fit via the puller bolt, furthermore in the region of the base plate a guide for additional force-measuring sensors is present and movable auxiliary devices can also be present.

An exercise device for compression exercises is adjustable in height and in compression force. The device includes a central housing and a plurality of plungers extending from a top side. A support member is attached to the housing on a bottom side. The support member is movable longitudinally relative to the housing and plungers from a fully retracted position to a fully extended position and is lockable in a plurality of intermediate longitudinal positions to vary the height of the device. Each plunger is operatively associated with an internal bias member that biases the plunger away from the housing. Resistance force on a plunger is adjustable via changing tension of the associated bias member with an adjustment knob to finely adjust tension. An installed bias member is removable and replaceable with a different bias member to coarsely adjust tension.

The present invention provides a human-computer interactive rehabilitation system, which can automatically calculate rehabilitation strength suitable for the patient, so that it is not necessary to manually evaluate and adjust the parameter settings in human-computer interactive rehabilitation system when different patients use it. At the same time, the human-machine interactive rehabilitation system and the hospital end can track the rehabilitation status and intervene through the data platform at any time. The platform establishes a cloud community feedback and encouragement mechanism, and immediately transmits the rehabilitation results to the designated barriers of the patients, provides patient encouragement feedback, and strengthens the community interaction and linkage in the medical relationship.

A hand training device and corresponding method are used for sensing and measuring a capacitance corresponding to the pressure or force applied by the hand or fingers of the user. This hand training apparatus has slots for the index finger, the middle finger, the ring finger, and the pinky finger. The data obtained from the device can be utilized to create a 3-D model to indicate grip strength exerted by the hand or pinch strength.
