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.

Overview

An anal sphincterotomy is the surgical incision or division of the sphincter muscle that controls the anal opening (anus). Generally, it is the first surgical choice for treatment of painful cracks or tears (fissures) that develop in the interior passageway of the distal anal canal where fecal matter is channeled for final elimination from the body. Fissures usually involve just the outer skin of the anus (epithelium) but also can involve the full thickness (anal mucosa). The procedure involves cutting through the outer areas of the opening to the rectum (anal sphincter) to stretch and relax tight internal muscles; this helps prevent excessive contractions (spasms). Surgery is reserved for the acute fissures that persist after unsuccessful medical treatment or for chronic or frequently recurring fissures.

Conservative treatment methods are tried first. When these treatments do not correct the problem, usually as a last resort, an anal sphincterotomy may be performed at the same time as a fissurectomy to remove (excise) painful fissures.

Anal fissures may occur when muscles of the anal sphincter begin to spasm as a stool passes, resulting in trauma to the anal canal. No work-related activity or specific occupation is associated with fissure development. Fissures most often develop in individuals who consume a low-fiber diet and have hard stools that are difficult to pass or who have persistent constipation. Fissures also may be linked to diseases including inflammation of the lining of the rectum (proctitis), inflammatory bowel disease (Crohn's disease or ulcerative colitis), leukemia, or certain types of cancer. In rare cases, syphilis or tuberculosis also may be an underlying cause of fissures.
