Sedentary Work Exerting up to 10 pounds (4.5 kg) of force occasionally and/or a negligible amount of force frequently or constantly to lift, carry, push, pull, or otherwise move objects, including the human body. Sedentary work involves sitting most of the time, but may involve walking or standing for brief periods of time. Jobs are sedentary if walking and standing are required only occasionally and other sedentary criteria are met.

Light Work Exerting up to 20 pounds (9.1 kg) of force occasionally and/or up to 10 pounds (4.5 kg) of force frequently, and/or negligible amount of force constantly to move objects. Physical demand requirements are in excess of those for Sedentary Work. Light Work usually requires walking or standing to a significant degree. However, if the use of the arm and/or leg controls requires exertion of forces greater than that for Sedentary Work and the worker sits most the time, the job is rated Light Work.

Medium Work Exerting up to 50 (22.7 kg) pounds of force occasionally, and/or up to 25 pounds (11.3 kg) of force frequently, and/or up to 10 pounds (4.5 kg) of forces constantly to move objects.

Heavy Work Exerting up to 100 pounds (45.4 kg) of force occasionally, and/or up to 50 pounds (22.7 kg) of force frequently, and/or in excess of 20 pounds (9.1 kg) of force constantly to move objects.

Very Heavy Work Exerting in excess of 100 pounds (45.4 kg) of force occasionally, and/or in excess of 50 pounds (22.7 kg) of force frequently, and/or in excess of 20 pounds (9.1 kg) of force constantly to move objects.

Job Classification

In most duration tables, five job classifications are displayed. These job classifications are based on the amount of physical effort required to perform the work. The classifications correspond to the Strength Factor classifications described in the United States Department of Labor's Dictionary of Occupational Titles. The following definitions are quoted directly from that publication.

Sedentary Work Exerting up to 10 pounds (4.5 kg) of force occasionally and/or a negligible amount of force frequently or constantly to lift, carry, push, pull, or otherwise move objects, including the human body.

Overview

Arthralgia (from Greek arthro [joint] and algos [pain]) literally means joint pain; it is a symptom (subjective complaint), not a disease. The symptom may be used as a diagnosis, such as ICD-9-CM 729.5, "pain in limb," until the true cause of the joint pain is determined. Or the symptom may be used as a diagnosis indefinitely if examination and testing are inconclusive, but the pain persists. Joint pain is a symptom of many different conditions that can be either localized or involve the whole body (systemic). Underlying causes may be articular (in the joint) or non-articular (outside the joint) in origin. Arthralgia may affect just one joint (monoarthralgia) or multiple joints (polyarthralgia). In general, involvement of only one joint suggests localized disease (joint specific), and pain in multiple joints indicates systemic disease.

Localized causes of arthralgia include infectious arthritis (septic arthritis), inflammation of a bursa (bursitis), avascular necrosis, tumor, inflammation of a tendon (tendinitis) or tendon sheath (tenosynovitis), or trauma. Systemic causes of arthralgia include osteoarthritis, fibromyalgia, crystal-induced arthritis (gout or pseudogout), polymyalgia, systemic lupus erythematosus, rheumatic fever, sickle cell disease, or rheumatoid arthritis. Lyme disease, influenza, and many other systemic bacterial and viral infections also can cause joint pain. Non-articular causes of joint pain may include disorders of bones, nerves, or blood vessels such as osteomyelitis, radiculopathy, nerve entrapment, or vasculopathy.

Arthralgia can be the initial presenting symptom for other systemic diseases. For example arthralgia may accompany colitis, especially with pain in the knees, ankles, and wrists. It may warn of endocarditis or be a side effect of rubella vaccination. It gives notice to the often-difficult-to-diagnose intestinal infection called Whipple's disease or heralds certain defects of immune function called cryoglobulinemia. It may be a consequence of the parvovirus B19 or be associated with the heart tumor myxoma.

Incidence and Prevalence: The exact incidence is not known because, as a symptom, arthralgia accompanies a broad range of disparate conditions. The prevalence of arthralgia increases with age.
