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.

Prognosis

Outcome of specific therapeutic procedures varies with diagnosis, severity of impairment, motivation, social support, and comorbidity. Some individuals may not return to their prior level of function due to inability to successfully treat the underlying condition, which may include progressive illnesses such as Parkinson's disease. However, with adaptive equipment, individuals can expect to participate in their prior activities to some degree.

Massage therapy has been shown to decrease muscle tightness, increase the flexibility of muscles and tendons, and promote healing of ligaments.

Acupressure may provide pain relief as a result of pressure applied to specific points on the body.

Hydrotherapy has been shown to promote increased range of motion and strength while decreasing stress throughout the body. Although a study found hydrotherapy to be less than effective in treating lower back pain, it is helpful in treating fractures from osteoporosis (Sinaki).

Electrical stimulation (TENS mode) has been shown to decrease pain. Muscle strength has been shown to increase when electrical impulses (NMES mode) are delivered to a muscle during therapeutic exercise to aid in muscle contraction. Another research study showed that TENS is not helpful for certain problems, such as pain in the lower back area. Other studies focused on PT and the elderly found that TENS effectively treats knee pain from surgery, such as arthroplasty of the knee.

Cold therapy has been shown to be effective in decreasing pain and swelling in an injured area.

Individuals who have pain in muscles and bones experience a positive outcome and reduction in pain from heat treatments, such as ultrasound, diathermy, fluidotherapy, and paraffin treatment.

Some studies show that hydrotherapy, TENS and ultrasound are not helpful for certain problems, such as low back pain. However, the efficacy of these therapies is debated because other studies—particularly a small study done on individuals with piriformis syndrome, a condition characterized by pain in the back and gluteal region causing traumatic sciatica—did demonstrate some improvement with ultrasound (Papadopoulos).
