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.

Rehabilitation

The type of rehabilitation for osteomyelitis depends on the location of the infected bone and the underlying cause of infection. For rehabilitation purposes, osteomyelitis is subdivided into five types. Depending on the type of osteomyelitis (ranging from type I to type V, according to the degree of tibia and fibula involvement and the bone’s ability to withstand functional loads), the rehabilitation time required varies. For type I osteomyelitis (in which both tibia and fibula are intact and can withstand functional loads), the rehabilitation time is from 6 to 12 weeks. In type II osteomyelitis (in which the tibia is intact, but a bone graft is needed), the rehabilitation time required is from 3 to 6 months. For type III osteomyelitis (in which the fibula is intact, but there is a tibial defect of no more than 6 cm), 6 to 12 months of rehabilitation are needed. In type IV osteomyelitis (in which the fibula is intact, but there is a tibial defect of more than 6 cm), 12 to 18 months of rehabilitation are required. Finally, for type V osteomyelitis (in which there is no usable intact fibula, and there is a tibial defect of more than 6 cm), 18 months or longer are required for rehabilitation.

In general, rehabilitation is aimed at restoring normal range of motion, flexibility, strength, and endurance. The goal of rehabilitation for progressive osteomyelitis is to maintain function and enhance mobility.

Active range of motion physical therapy initially helps maintain flexibility and strength and relieves the musculoskeletal pain associated with muscular weakness, paralysis, and immobility. As the therapy progresses, passive range of motion exercises are preferable to avoid overexertion or possible damage to the muscles. In the event of muscle weakness to the legs, balance exercises may be utilized.

As strength continues to progress, endurance becomes a focus in the individual's rehabilitation program for osteomyelitis. Aerobic exercises that increase cardiovascular fitness are recommended. The American Heart Association recommends 30 to 60 minutes of aerobic activity 3 or 4 times a week.

Learning how to avoid injury is another important intervention in the rehabilitation of progressive osteomyelitis. Occupational therapy helps individuals arrange their homes and organize their lives in ways that support their physical and mental well-being. Activities are also provided to relieve the mental boredom of inactivity. Devices and techniques that help the individual communicate are invaluable in maintaining peace of mind. The rehabilitation program varies among individuals with progressive osteomyelitis as the intensity and progression of the exercise depends on the stage of the disease and individual's overall health.
