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.

Comorbid Conditions

Factors Influencing Duration

Duration depends on the type of vertigo, the underlying cause for the vertigo, the individual's age and response to treatment, and the extent, if any, of complications. Acute vertigo is self-limited with a duration of a few days. Chronic vertigo may persist indefinitely.

Medical Codes

ICD-9-CM:
386.10 - Vertigo, Peripheral, Unspecified
386.11 - Benign Paroxysmal Positional Vertigo; Benign Paroxysmal Positional Nystagmus
386.19 - Vertigo, Peripheral, Other and Unspecified; Aural Vertigo; Otogenic Vertigo
386.2 - Vertigo of Central Origin; Central Positional Nystagmus; Malignant Positional Nystagmus
438.85 - Late effects of cerebrovascular disease; Vertigo
780.4 - Dizziness and Giddiness; Light-headedness; Vertigo NOS

Prognosis

Acute vertigo is usually self-limited and resolves after several days of bed rest. The prognosis for other types of vertigo varies greatly, depending on the underlying cause. In many cases of chronic vertigo, changes in lifestyle may become necessary, such as avoiding positions of the head or body that aggravate or induce symptoms. Chronic diseases such as autoimmune disorders or multiple sclerosis that fail to resolve may cause continuing episodes of vertigo for an indefinite time. The success rates for various surgical procedures aimed at resolving or relieving the symptoms of more serious forms of vertigo range from 60% to 90%. Permanent hearing loss may accompany these surgical procedures.
