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.

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.

ICD-9-CM:
595.1 - Cystitis, Chronic Interstitial; Hunners Ulcer; Panmural Fibrosis of Bladder; Submucous Cystitis

Definition

Interstitial cystitis is an inflammation of the urinary bladder. Pinpoint areas of bleeding (glomerulations) develop in the bladder wall, resulting in scar tissue that causes the bladder to stiffen and contract, making it less able to expand, and markedly reducing its capacity. Interstitial cystitis is much less common than cystitis caused from a bacterial urinary tract infection.

The exact cause of interstitial cystitis is unknown. Possible causes include disorders in which the body's immune system mistakenly attacks the bladder (autoimmune disorder), an allergic reaction, hormonal disturbances, defects in the mucous lining that normally protect the bladder, the presence of toxic substances in the urine, or an abnormality of the spine. Interstitial cystitis might also be related to scarring from a condition in which fragments of the uterine lining are found in other parts of the pelvic cavity (endometriosis) or from surgical removal of the uterus (hysterectomy), since women who experience interstitial cystitis more commonly have both these conditions.

Biological risk factors include previous urinary tract infections, gynecological surgery and immunological disease. Some research is investigating possible genetic factors of IC.

Risk: The approximate 700,000 women diagnosed with this condition account for about 90% of cases the US, with a median age of 43 (Metts 1199).

Incidence and Prevalence: Interstitial cystitis occurs in approximately 60 out of 100,000 women in the US (Rovner).
