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.

Factors Influencing Duration

The severity of the disorder, effectiveness of treatment, and interference with job requirements influence the length of disability. Medication used to treat tics or ADHD can have side effects that may lengthen disability.

Medical Codes

ICD-9-CM:
307.20 - Special Symptoms or Syndromes, Not Elsewhere Classified; Tic Disorder, Unspecified
307.22 - Special Symptoms or Syndromes, Not Elsewhere Classified; Chronic Motor or Vocal Tic Disorder
307.23 - Special Symptoms or Syndromes, Not Elsewhere Classified; Gilles De La Tourettes Disorder; Motor-verbal Tic Disorder

Prognosis

There is no cure for Tourette's disorder and it almost always persists throughout life, but many individuals with this condition show improvement when they get older (by age 18, about 50% of individuals are free of tics (Robertson)). However, associated neuropsychiatric disorders such as depression, panic attacks, mood swings, and antisocial behavior may increase the level of severity. The primary goal of treatment is not the complete elimination of tics but rather suppression of tics to the point at which the individual can function normally. Even without treatment, symptoms can go into remission and then recur, but with treatment, many individuals can experience a significant reduction in symptoms. There is a reduction in tic severity with antipsychotic medication (Robertson).
