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.

Overview

The spinal column (vertebral column) is made up of 24 movable bones, or vertebrae (7 cervical vertebrae, 12 thoracic vertebrae, and 5 lumbar vertebrae) and 2 fused sections (the sacrum and the coccyx). An intervertebral disc disorder is a protrusion or herniation of one of the gel-like cushions (discs) that separate the vertebrae of the spine. The displaced gel (nucleus pulposus) of the disc may seep through the torn or stretched outer covering of the disc (annulus fibrosus) and press against the spinal nerves or the spinal cord itself, causing changes in sensory, motor, and reflex function (radiculopathy).

Disc disorders of the upper (cervical), mid (thoracic), and lower (lumbar) spine are discussed separately. See Cervical Disc Disorder with Myelopathy, Thoracic Disc Disorders with Myelopathy, and Lumbar Disc Disorders with Myelopathy for more information.
