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.

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.

  • Other neurological conditions
  • Psychiatric disorders

Factors Influencing Duration

Factors influencing duration may depend on the type of trigeminal neuralgia, the frequency and severity of attacks, the individual's underlying condition, response to therapies, and presence of complications.

Medical Codes

ICD-9-CM:
053.12 - Herpes Zoster with Nervous System Complications, Other; Postherpetic Trigeminal Neuralgia
350 - Trigeminal Nerve Disorders
350.1 - Trigeminal Neuralgia; Tic Douloureux; Trifacial Neuralgia; Trigeminal Neuralgia NOS

Complications

Toxic side effects of the drugs used to control pain can damage the liver; liver function needs close monitoring. Bone marrow and blood disorders are also associated with anticonvulsant therapy and may include agranulocytosis, aplastic anemia, or suppression of the white blood cell count; therapy can continue, but close monitoring with complete blood counts is required.

Surgical procedures can cause numbness of the face or eye that may in itself be unpleasant (anesthesia dolorosa) and may lead to complications such as corneal abrasion. Serious complications leading to death are rare, but in individuals with surgical microvascular decompression may include hemorrhage, infection, and brainstem damage around the area of the procedure (Burchiel).

There may be residual facial numbness, jaw weakness, or corneal numbness following radiofrequency trigeminal gangliolysis. Hearing disturbances occur in 11% of individuals following percutaneous balloon microcompression (Burchiel).
