- mean time to recovery — (specification) (MTTR) The average time that a device will take to recover from a non-terminal failure. Examples of such devices range from self-resetting fuses (where the MTTR would be very short, probably seconds), up to whole systems which have to be replaced. The MTTR would usually be part of a maintenance contract, where the user would pay more for a system whose MTTR was 24 hours, than for one of, say, 7 days. This means the supplier is guaranteeing to have the system up and running again within 24 hours (or 7 days) of being notified of the failure. Some devices have a MTTR of zero, which means that they have redundant components which can take over the instant the primary one fails, see RAID for example. See also Mean Time Between Failures.

- 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.
