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.

Amputation


Specialists

  • General Surgeon
  • Orthopedic (Orthopaedic) Surgeon
  • Physiatrist (Physical Medicine and Rehabilitation Specialist)
  • Vascular Surgeon

Comorbid Conditions

  • Cardiovascular disease
  • Diabetes mellitus
  • Other body parts injured by the trauma that caused the amputation
  • Peripheral vascular disease

Factors Influencing Duration

Presence of underlying disease such as diabetes or PVD in the retained limb(s), and atherosclerosis in other areas (coronary artery disease, cerebrovascular disease) will influence recovery time and an individual’s return to ambulation and activities. Additionally, the presence of complications, the particular limb or digit amputated, whether an amputated upper limb is the dominant limb, the individual's psychological status, whether or not a prosthesis will be used, the individual’s adaptation to the prosthesis, and the individual's job requirements may influence length of disability.

Prognosis

Surgical technique, postoperative rehabilitation and prosthetic design have improved greatly since mid-1900s, allowing most individuals who undergo amputation to return to high levels of functioning after reconstruction and rehabilitation. Amputations usually succeed in arresting the spread of infection or cancer. Amputation does not correct underlying conditions such as PVD or diabetes, which will still require medical treatment. Repeat surgery may sometimes be necessary in these individuals to remove more of a limb or, in advanced stages of diabetes or PVD, another limb. Although loss of part or all of an extremity always produces some degree of permanent disability, individuals undergoing amputation of a lower extremity are highly likely to be ambulatory. Younger individuals even have prostheses that encourage a return to recreational activities and competitive sports. Upper extremity prostheses typically provide partial return of normal function. However, amputations of fingers, and especially the thumb, often reduce the ability to perform tasks involving manual dexterity.
