Achilles tendonitis - Inflammation of the Achilles tendon.

activities of daily living (ADLs) - personal care activities necessary for everyday living, such as eating, bathing, grooming, dressing, and toileting; a term often used by healthcare professionals to assess the need and/or type of care a person may require.

amyotrophic lateral sclerosis (ALS) - a terminal neurological disorder characterized by progressive degeneration of motor cells in the spinal cord and brain. It is often referred to as "Lou Gehrig's disease."

aneurysm - a weakened, pouched area on the wall of an artery.

ankle sprain - overstretched lateral (outside) ligament of the ankle joint.

arrhythmia - an abnormal heart rhythm.

arthralgia - pain in a joint, usually due to arthritis or arthropathy.

arthroscopy - a minimally-invasive diagnostic and treatment procedure used for conditions of a joint. This procedure uses a small, lighted, optic tube (arthroscope) which is inserted into the joint through a small incision in the joint. Images of the inside of the joint are projected onto a screen; used to evaluate any degenerative and/or arthritic changes in the joint; to detect bone diseases and tumors; to determine the cause of bone pain and inflammation.
