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.

Factors Influencing Duration

Factors include occupation, age, and conditioning of the individual. Compliance with treatment and recommended home care will influence the duration. Any conditions affecting the spine could prolong recovery. The individual's need and ability to obtain secondary gains from the pain could lengthen disability time. Psychological assessment is crucial in cases with prolonged disability and no obvious specific spinal disorder.

Medical Codes

ICD-9-CM:
724.2 - Lumbago; Low Back Pain; Low Back Syndrome; Lumbalgia

Causation and Known Risk Factors

An initial episode of back pain typically occurs between 30 and 40 years of age. The likelihood of having low back pain increases with age. However, the condition has become increasingly prevalent in pre-teens and teens, and has been attributed to weighty backpacks and incorrect posture while using video games and computers. Overall deconditioning is also likely to contribute to low back pain. Added stress to the back from any cause such as obesity, pregnancy, or unnatural curvature or disease of the spine can increase the risk for back pain. Occupational risk factors include lifting objects while twisting or without properly bending the legs, heavy pushing or pulling, and vibrational stresses. A family history may predispose individuals to some causes of back pain, such as degenerative disc disease.
