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. 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.

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.

Multiple Myeloma


Failure to Recover

If an individual fails to recover within the expected maximum duration period, the reader may wish to consider the following questions to better understand the specifics of an individual's medical case.

Regarding diagnosis:

  • Does individual have pain in the bones, especially the vertebrae, pelvis, ribs, and skull?
  • Does individual have history of recurrent bacterial infections?
  • Does individual show symptoms such as nausea, confusion, frequent urination (polyuria), and constipation?
  • Were other conditions with similar symptoms such as MGUS, chronic lymphocytic leukemia, non-Hodgkin's lymphoma, primary amyloidosis, metastatic carcinoma, bone neoplasms, and macroglobulinemia ruled out?
  • Did CBC show anemia? Were blood chemistry tests performed? What were the results?
  • Has diagnosis of multiple myeloma been confirmed?

Regarding treatment:

  • Has chemotherapy been effective in slowing progression of the disease?
  • Has radiation therapy helped manage pain?
  • Are complications such as anemia or infections being effectively treated with blood transfusions and antibiotics, respectively?
  • Is individual a candidate for bone marrow transplant? Does individual have a matched sibling donor?
  • Is skeletal damage being prevented?
  • Are hypercalcemia and renal failure being treated with increased fluid intake, glucocorticoids, and chemotherapy?

Regarding prognosis:

  • Has treatment been effective in slowing progression of the disease?
  • Have complications been avoided or responded to treatment?
  • Is pain being adequately managed?
  • Did any complications occur such as infection, destruction of bone tissue, spinal cord compression with possible neurological impairment, kidney damage or failure due to increased levels of calcium released during bone destruction and excess immunoglobulin in the blood, or anemia or bleeding disorders?
  • Does individual have an underlying condition (other chronic disease such as diabetes, heart disease, kidney disease or lung disease) that may impact recovery?
  • Would individual benefit from psychological counseling or enrollment in a multiple myeloma support group?
