wrist

 [rist]
the region of the joint between the hand and the forearm; it contains eight bones, called the carpal bones (see anatomic Table of Bones in the Appendices). The bones are arranged in two rows, whose joint surfaces glide upon each other in four directions; they join the bones of the forearm, the radius and ulna, as well as the bones of the hand, the metacarpals. They are bound together and protected by tough ligaments and capsules, the enveloping structures. The major arteries, nerves, veins, and tendons that serve the hand and fingers run across the wrist. Both the tendons and the joint are lined with synovial membrane. Called also carpus.

wrist

The complex, many-boned joint between the hand and the arm. The eight wrist bones, or carpals, are arranged in two rows, the nearer row, which articulates with the forearm bones, containing the scaphoid, lunate, triquetral, and pisiform bones, and the farther row the trapezium, trapezoid, capitate, and hamate. These are connected to the bones of the palm, the metacarpals. Many tendons, connecting forearm muscles to the fingers and thumb, run through the wrist. These pass under ligamentous straps (retinacula) which prevents them from springing away from the wrist. Arteries and nerves also pass through the wrist.

The MCP joint collateral ligaments of the thumb and lesser digits extend with slight obliquity from shallow depressions on the radial and ulnar aspects of the metacarpal heads to the bases of the proximal phalanges.
This stabilises the IP joint in extension and causes semi active flexion at the MCP joint and allows pulp-to-pulp pinch.
In a typical WDFHO structure, the wrist extension torque ([T.sub.1]) is transferred to the MCP joint through the four bar linkages system.
Reflective markers were placed on the tip of the index finger, the index PIP joint, the index MCP joint and the thumb tip of the hemiparetic hand (figure 2).

Although these hands use a form of a four-bar linkage, each has a distinct method of coupling the motion of the PIP to the motion of the MCP joint. The Vincent finger (Figure 2(a)) uses two externally located wire links mounted between the finger base and the distal link.
Whether these signs or other secondary impairments develop, such as MCP instability and/or carpo-metacarpal (CMC) (sub) luxation, depends on such factors as hand dominance and use, duration of the palsy, configuration of MCP joint surfaces and joint laxity.
* Posture 3 defines a 90[degrees] angle for all the fingers' MCP joints: ([[theta].sub.21], [[theta].sub.31], [[theta].sub.41], and [[theta].sub.51] = 90[degrees]).
Swelling, warmth, limitation of movement, and tenderness were noted at the ankle, wrist, PIP and MCP joints bilaterally.
The novel 4-DOF planar robot consists of four revolute joints, each one representing the proximal interphalangeal (PIP) and MCP joints of the thumb and index finger (Figure 2).
In brief, the Prayer sign was defined as positive when subjects were unable to oppose palmar surfaces at any interphalangeal or MCP joint. To measure the angle of active maximal flexion of the fifth MCP joint, the fourth finger was fixed on a flat surface and the subject was asked to actively perform the flexion of the fifth finger at the level of the MCP joint.
