Tenodesis grasp and release is an orthopedic observation of a passive hand grasp and release mechanism, affected by wrist extension or flexion, respectively.It is caused by the manner of attachment of the finger tendons to the bones and the passive tension created by two-joint muscles used to produce a functional movement or task (tenodesis).

Freefly Systems gained notoriety within the digital video production industry after the launch of the Mōvi M10 camera stabilizer [2] that provided a smaller and lighter alternative to the Steadicam. [3] The Mōvi M10 eliminated the need for camera operators to wear a harness with an iso-elastic arm and counterbalance weight to get steady shots ...
A gyroscopic wrist exerciser. Video showing the use - from starting the rotation with a 'shoestring' over various movements with the holding hand until stopping the rotor with the second hand. The demonstrated speeds are, in part, very high and not recommended for normal exercise due to the resulting high forces.
Rotational wristlock by an Aikido instructor. A rotational wristlock (in budo referred to as kote hineri, and in Aikido referred to as a type of sankyō, 三教, "third teaching") [5] [6] is a very common type of wristlock, and involves forced supination or pronation of the wrist, and is typically applied by grabbing and twisting the hand.
Consequently, on the application of any force on the bow, e.g. (1) muscular force, whether voluntary or involuntary: (2) the reaction of the bow to the acceleration of the bow limbs, string and arrow: (3) the further reaction of the bow as the string becomes taut and the arrow flies free: the actual physical movement of the bow centre section ...
The tendon of the flexor carpi radialis is visible on the anterior surface of the forearm, just proximal to the wrist, when the wrist is flexed. It is the tendon seen ...
The wrist curl is a weight training exercise for developing the wrist flexor muscles, the muscles in the front of the forearm. [1] It is therefore an isolation exercise. Ideally, it should be done in combination with the "reverse wrist curl" (also called wrist extension) which works out the muscles comprising the back of the forearms, [1] to ensure equal development of the wrist flexor and ...
Wrist structures prone to injury are the triangular fibrocartilage complex and the scapholunate ligament. [1] Wrist sprains may occur when a ligament is ruptured or lacerated in severe trauma, stretched or twisted. [1] Commonly, wrist pain is caused by sudden load-bearing or twisting effects, such as falling from a height with an outstretched ...
