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

729.2 - Neuralgia, Neuritis, and Radiculitis, Unspecified

Overview

Neuralgia is pain in the distribution of one or more nerves caused by a change in structure or function of the nerves (nerve injury) instead of the normal stimulation of healthy pain receptors. Neuralgia falls into two categories: central neuralgia, where the cause of the pain is neuronal injury in the spinal cord or brain, and peripheral neuralgia, with nerve irritation or injury secondary to trauma, compression, infection, or systemic disease.

Peripheral neuropathy is inflammation or degeneration of the nerves outside the brain or spinal cord. The peripheral nerves are responsible for sensation, movement, gland or organ function, and other aspects of health. Depending on the type of nerve affected, damage to these nerves may result in pain, changes in sensation (pins & needles [paresthesia]), or loss of muscle strength (weakness [paresis] or paralysis). Examples of possible causes include systemic diseases (such as diabetes or leprosy), vitamin deficiency (vitamin B12), poor nutrition states, toxic exposure, traumatic injury, excessive alcohol consumption, medication (e.g., chemotherapy), immune system disease or infection, or inherited (present from birth) genetic factors.

If the neuropathy is affecting just one nerve it is called "mononeuropathy," while neuropathy involving multiple nerves in roughly the same areas on both sides of the body is referred to as "symmetrical polyneuropathy" or "polyneuropathy." If two or more separate nerves in dissimilar areas of the body are affected it is called "mononeuritis multiplex," "multifocal mononeuropathy," or "multiple mononeuropathy."

Peripheral neuropathy may be acute or chronic. Acute neuropathy often has sudden onset, rapid progression, and slow resolution, while chronic neuropathy is a long term condition where symptoms begin subtly and progress slowly over time. Acute neuropathies demand urgent diagnosis.

Neuritis is a general term for inflammation of a nerve or the general inflammation of the peripheral nervous system. Neuritis is a term used loosely to describe symptoms of pain or numbness; impaired strength (muscular atrophy and even paralysis) and sensation (numbness [hypoesthesia], anesthesia); and defective reflexes. The term "neuritis" should be reserved for diseases in which actual nerve inflammation occurs, such as optic neuritis seen in multiple sclerosis.

Radiculitis (radicular pain) is a nonspecific term used loosely to describe pain or numbness in the distribution of a single spinal nerve root. Radiculitis is thought to occur from inflammation of nerve roots found within the lowest portion of nerves within the spine. A common form of radiculitis is sciatica— radicular pain that radiates along the sciatic nerve from the lower spine to the gluteal muscles, back of the upper thigh, calf, and foot. Sciatica often occurs secondary to nerve root irritation from a spinal disc herniation or from osteophytes in the lumbar region of the spine.

These terms can represent a vague diagnosis which can sometimes be refined to a more specific cause.
