Arthritis affects one out of every five Americans – an estimated 52.5 million people – and is the leading cause of disability in the nation. The condition itself can make it difficult and painful to conduct even the most mundane daily tasks such as walking, climbing stairs, using a computer, or brushing your teeth. The term “arthritis” encompasses over 100 rheumatic conditions that impact the body’s joints, causing pain and inflammation to those who suffer with it.
