Joints: WristIn human anatomy, the wrist is the flexible and narrower connection between the forearm and the palm. The wrist is essentially a double row of small short bones, called carpals, intertwined to form a malleable hinge. The wrist-joint (articulatio radiocarpea) is a condyloid articulation allowing three degrees of freedom. The parts forming it are the lower end of the radius and under surface of the articular disk above; and the scaphoid, lunate, and triquetral bones below. The articular surface of the radius and the under surface of the articular disk form together a transversely elliptical concave surface, the receiving cavity. The superior articular surfaces of the scaphoid, lunate, and triquetrum form a smooth convex surface, the condyle, which is received into the concavity. The bones of the wrist can be easily remembered by the Acronym SLTPTTCH - Some Lovers Try Positions That They Can't Handle. These represent the bones in order of proximal row lateral to medial and then distal row lateral to medial: Scaphoid Lunate Triqetrium Pisiform Trapezium Trapezoid Capitate Hamate. One of the most common forms of wrist pain is carpal tunnel syndrome or Median Neuropathy at the Wrist is a medical condition in which the median nerve is compressed at the wrist, leading to pain, paresthesias, and muscle weakness in the forearm and hand. A form of compressive neuropathy,carpal tunnel syndrome is more common in women than it is in men, and, though it can occur at any age, has a peak incidence around age 42. The lifetime risk forcarpal tunnel syndrome is around 10% of the adult population. The Xtensor is a device that helps to reduce or eliminate pain associated withcarpal tunnel syndrome . To maintain a healthy, normal balance, The Xtensor conditions the Finger Extensor Muscles and increases their ability to handle the stress placed on them during the daily activities that contributed to the problem in the first place. The Xtensor works quickly to develop the Strength and Endurance of the Finger Extensor Muscles providing the necessary stabilizing effects to reduce the risk of Tendonitis in the Wrists and Elbows. The Xtensor is the first product able to precisely target and strengthen the Finger Extensor Muscles while also providing a full, natural path of motion necessary for stimulating the muscles in the elbow. Using The Xtensor strengthens muscles virtually off limits to all other devices. The most well known repetitive strain injury is Carpal tunnel syndrome, which is common among guitarists as well as assembly line workers but relatively rare among computer users: computer-related arm pain is generally caused by another specific condition. |
