- overuse strain injury — (medical) (Or "repetitive strain injury", RSI, "repetitive strain disorder") Any tendon or muscle injury resulting from overuse, usually in the hand, wrist, or arm. Injury may be caused by any combination of repetitive, unacustomed, or prolonged movements, forcefulness, or an awkward position (often due to bad ergonomics). The symptoms are pain, tingling, weakness, numbness, swelling, cracking, stiffness, or reduced coordination. Common conditions are: Carpal tunnel syndrome, where swelling of the membrane linings in your wrist surrounding the tendons that bend your fingers compresses the median nerve. This may result in numbness and pain in the hand, arm, shoulder, and neck. Tennis elbow, where rotating your wrist and using force causes a form of epicondylitis. Tendinitis, where unacustomed exercise or repeated awkward movements inflame wrist, elbow, or shoulder tendons, often leading to severe stiffness. Trigger finger, a popping or catching sensation when you bend your finger, wrist, or shoulder. This form of tenosynovitis is caused by repetitive hand movements. To prevent the condition worsening, treat the pain with heat, cold, or aspirin, ibuprofen, or naproxen sodium; rest; or immobilise the injured area with a splint or bandage. See a doctor.

The presence of the ABI specification in the POE distinguishes it from other open systems (POSIX, XPG4, etc.) since it allows platform independent binary compatibility which is otherwise typically limited to particular hardware. The POE is an open standard, derived from AIX and conforming to industry open standards including POSIX, XPG4 and Motif. The POE specification will be publicly available to anyone wishing to produce either application programs or hardware platforms. The PowerOpen Association will provide the necessary conformance testing and POE branding. The POE is hardware bus independent. System implementations can range from laptop computers to supercomputers. It requires a multi-user, multitasking operating system. It provides networking support, an X Window System extension, a Macintosh Application Services extension and Motif. It is conformance tested and certified by an independent party (the PowerOpen Association). The POE specification is targeted for availability in the first quarter of 1994. The PowerOpen Association will soon have some of the information material available on-line.
