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.

Medical Codes

ICD-9-CM:
799.21 - Nervousness

Diagnosis

History: Individuals may complain of disturbances in sleep, eating, and drinking patterns. They may describe feelings of restlessness, apprehension, irritability or inability to relax, which may be associated with other symptoms such as fatigue, headaches, pain, muscle tension, sweating, blushing, nausea, diarrhea, frequent urination, rapid breathing, difficulty breathing, tremor, numbness and tingling of the extremities and face, or a pounding or irregular heartbeat. They may report a recent event, such as family or work issues, or a traumatic experience, that may have triggered their symptoms. They may describe circumstances that make their symptoms worse or those that make their symptoms better.

Physical exam: A physical exam may reveal abnormal behaviors, including restlessness, pacing, rapid (pressured) speech, stuttering, stereotyped jerking movements or gestures (tics), or inappropriate giggling or silence. The exam may reveal muscle tension as the cause of headaches, neck spasms, and back pain. There may be excessive blushing or sweating, pale skin, hand tremors, an overly firm or weak handshake, or an inability to relax. When the nervous state is being caused by an underlying medical condition, such as an endocrine imbalance, other physical symptoms such as rapid heart and respiratory rate, fever, or weight loss may be noted. If the nervousness is not accompanied by other physical signs and symptoms, a psychological cause may be suspected. A referral for psychiatric evaluation may be necessary.

Tests: Diagnostic tests may include lab studies to rule out medical causes of the nervousness. This may include a complete blood count, thyroid panel, chemistry panel, and possibly an electrocardiogram. If there are no obvious causes for the nervousness, psychological testing may be done to rule out an underlying psychiatric disorder.
