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

Nervous or mental breakdown refers to a sudden deterioration in mental and emotional function brought on by severe stress. Beyond this most general connotation, the term lacks clinical specificity and is no longer in professional use. Historically the term derived from terms "nervous exhaustion" and "neurasthenia" coined in the nineteenth century, in an era when disorders since regarded as emotional, were felt to be of neurological origin. The term is currently used in popular culture, as is the term "stress" and is of little medical utility.

As there are many medical and psychiatric conditions that could be referred to with the term, it is therefore not an appropriate or sufficiently specific diagnosis for the purposes of a disability claim.

Some of the more common psychiatric causes of "mental breakdown" include schizophrenia, depression, acute stress disorder, post-traumatic stress disorder, and bipolar mood disorder. Non-psychiatric causes commonly include glandular and metabolic disturbances (especially of the thyroid), infections, lupus, various cancers, a wide variety of neurological diseases such as stroke, multiple sclerosis, vasculitis, encephalitis, and Parkinson's disease, as well as side effects of various prescription and over-the-counter medications. There may also be complicating factors such as alcohol or drug use.

This is a vague term falling far short of a diagnosis. Contact physician for additional information.
