Real-time strategy (RTS) refers to a time-based video game that centers around using resources to build units and defeat an opponent. Real-time strategy games are often compared to turn-based strategy games, where each player has time to carefully consider the next move without having to worry about the actions of his opponent.
There is no cure for ankylosing spondylitis. Treatments can improve symptoms and possibly prevent worsening. This may include medication, exercise, and surgery. Medications used include NSAIDs, steroids, disease modifying antirheumatic drugs such as methotrexate, and biologic agents such as infliximab.
Ankylosing spondylitis is a form of chronic inflammation of the spine and the sacroiliac joints. The sacroiliac joints are located at the base of the low back where the sacrum (the bone directly above the tailbone) meets the iliac bones (bones on either side of the upper buttocks) of the pelvis.
