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.

Comorbid Conditions

Factors Influencing Duration

Factors that might influence the length of disability include the severity of symptoms, the presence, or absence, of nerve root or spinal cord dysfunction (radicular signs), the mode of treatment, the response to treatment, the presence of an underlying condition such as degenerative disc disease or other chronic or progressive illness, and the physical requirements of the individual's job.

Overview

Neck pain is not a disease or injury, but a symptom. Neck pain can be of traumatic or atraumatic origin, and/or associated with systemic disease. Neck pain complaints with no other physical signs may be related to a cervical strain or sprain type injury. Most neck pain, however, develops spontaneously with no known trauma. Cervical spine pain also may be associated with shoulder pathology. The symptoms of neck disorders, and the symptoms of shoulder disorders frequently overlap, making it at times challenging to determine whether an individual has a neck problem, a shoulder problem, or both. When not attributable to a more serious and definite cause, neck pain is often called cervicalgia.

The neck or cervical spine includes seven cervical vertebrae and has 37 joints. It supports the head, and moves the head in space hundreds of times an hour. Causes of neck pain include musculoskeletal conditions, neurological conditions, systemic conditions (e.g., osteoarthritis), and rheumatoid-related conditions (e.g., rheumatoid arthritis, polymyalgia rheumatica). Neck pain may be related to soft tissue disorders, sustained use or sustained immobility of the neck, structural abnormalities, joint degeneration, psychological stress, or trauma. Soft-tissue-related neck pain can be caused by consistently poor posture while sitting or standing, repetitive activity, sports injuries, or the presence of an underlying condition such as a cervical disc degeneration or cervical disc herniation. Referred neck pain may originate from conditions in any organ system, including myocardial ischemia, gallbladder disease, hiatal hernia, gastrointestinal ulcers, and pancreatitis.

Neck pain is considered chronic when it has continued for at least 6 consecutive months. The etiology of chronic neck pain may be difficult to determine. Considerations include cervical zygapophyseal (facet) disorders, pain following a "whiplash" injury, soft tissue injury, cervical disc disease, and other conditions listed above. A link has also been suggested between chronic neck pain and the individual's psychological state; many chronic pain conditions are believed to have some psychological impact or component.

Incidence and Prevalence: Neck pain is one of the most frequent complaints encountered by primary care physicians and neuromusculoskeletal specialists. The lifetime prevalence of clinically significant neck pain is 40% to 70% (Rindfleisch); the one-year prevalence is 16% to 18% (Hunter).
