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.

Comorbid Conditions

Factors Influencing Duration

Factors that may influence the length of disability include the general health and fitness of the individual before being diagnosed with AD, evidence of preexisting diseases affecting any of the major body systems (e.g., diabetes, chronic obstructive lung disease, and chronic heart disease), diagnosis of an acute disease or condition that requires surgery, the individual's mental and emotional stability, access to rehabilitation facilities and home health care, and the strength of the individual's support system.

Medical Codes

ICD-9-CM:
331.0 - Cerebral Degenerations, Other; Alzheimers Disease

Failure to Recover

If an individual fails to recover within the expected maximum duration period, the reader may wish to consider the following questions to better understand the specifics of an individual's medical case.

Regarding diagnosis:

  • Was a presumptive diagnosis of AD made?
  • Were underlying medical and psychological conditions identified or ruled out?
  • Is caregiver diligent in alerting individual's physician to changes in behavior, movement, consciousness, and bodily functions?
  • Has individual experienced health-related complications?
  • How are coexisting conditions being addressed?

Regarding treatment:

  • To what extent is individual impaired?
  • Can individual and/or family members still adequately care for needs? Would family benefit from social services in making long-range plans? Has family accessed appropriate services to care for individual?

Regarding prognosis:

  • Are individual and family realistic in planning for the future?
  • Will family be able to care for individual in home?
  • Were other options investigated?
