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.

Factors Influencing Duration

The individual's response to treatment and the site, severity, and underlying cause of tenosynovitis can affect the length of disability. Injections of corticosteroids sometimes increase pain for several hours to days. Restricted joint motion may limit dexterity and create safety issues at the work site.

Medical Codes

ICD-9-CM:
727.00 - Synovitis and Tenosynovitis, Unspecified; Synovitis NOS; Tenosynovitis NOS
727.01 - Synovitis and Tenosynovitis in Diseases Classified Elsewhere
727.04 - Radial Styloid Tenosynovitis; de Quervains Disease
727.05 - Other Tenosynovitis of Hand and Wrist
727.06 - Tenosynovitis of Foot and Ankle

Causation and Known Risk Factors

Individuals at risk for tenosynovitis of the upper extremities include carpenters, painters, welders, swimmers, tennis players, and baseball players. Although wrist tenosynovitis usually occurs in individuals who perform repetitive grasping or pinching motions with the thumb, it sometimes develops spontaneously in pregnant women. Runners, who engage in repetitive movements of the lower extremities, are at risk of tenosynovitis of the knee, ankle, and foot, but this type of tenosynovitis is less common. Women are more prone than men to irritative or frictional tenosynovitis.

Most causes of tenosynovitis are unknown. Irritation to the synovial lining can be related to injury, overuse, repetitive strain, trauma, rheumatoid arthritis (RA), or infection, any of which may increase the symptoms of tenosynovitis.

Gonococcal tenosynovitis, a complication of gonorrhea, typically affects teenagers and young adults. Common sites of infection include the top (dorsum) of the hand, wrist, and ankle. Other types of infectious tenosynovitis may result from puncture wounds or lacerations, usually to the hands.
