Table 1-2
Activities of Daily Living Commonly Measured in Activities of Daily Living (ADL) and Instrumental Activities of Daily Living (IADL) Scales
| ||||||||||||||||||
ADL | See Activities of daily living (ADL). | ||||||||||||||||||
Aggravation | A factor(s) (eg, physical, chemical, biological, or medical condition) that adversely alters the course or progression of the medical impairment. Worsening of a preexisting medical condition or impairment. | ||||||||||||||||||

Chronic pain | Pain that extends beyond the expected period of healing or is related to a progressive disease. It is usually elicited by an injury or disease but may be perpetuated by factors that are both pathogenically and physically remote from the original cause. Because the pain persists, it is likely that environmental and psychological factors interact with the tissue damage, contributing to the persistence of pain and illness behavior. | ||||||||||||||||||
Combined Values Chart | A method used to combine multiple impairments, derived from the formula A + B(1−A) = combined values of A and B, which ensures that the summary value will not exceed 100% of the whole person. | ||||||||||||||||||

The definition of legal blindness varies slightly in different statutes. A common definition is “visual acuity of 20/200 or less.” Implementation of this definition depends on the chart used (see Section 12.2b.1). An alternative definition is “visual field loss to a 20° diameter or less.” This definition does not address nonconcentric field losses. | |||||||||||||||||

Occupational history | A tool used in a comprehensive clinical assessment to obtain, organize, and assess information about the current and prior workplace environments and exposures and their relationship to illness and injury. An occupational history can provide essential information to improve treatment, prevent further or additional illness or injury, and assist in the determination of whether work directly caused or contributed to the development of the injury or illness. | ||||||||||||||||||
Pain | An unpleasant sensory and emotional experience associated with actual or potential tissue damage or described in terms of such damage. | ||||||||||||||||||
Pain behavior | Verbal or nonverbal actions understood by observers to indicate that a person may be experiencing pain, distress, and suffering.

Remission | Improvement or a state or period during which the symptoms of a disease are abated. | ||||||||||||||||||
Replacement medication or therapy | Treatment that involves the supply of something (an element, compound, or hormone) lacking or lost to the body's system. Although the person may be fully functional on an everyday basis while taking replacement medication, he or she may be unable to respond properly to stresses such as fever, trauma, or infection. This impaired ability to respond to stress needs careful consideration. | ||||||||||||||||||

Teleroentgenography | A radiographic method used to determine actual limb length. | ||||||||||||||||||
Tinnitus | A sensation of noise (such as ringing or roaring) in the ear. Tinnitus may be audible or inaudible. Audible tinnitus is usually associated with a muscular tic or vascular bruit. Inaudible tinnitus can be heard only by the person affected and may be associated with an obstruction of the external auditory canal or a disturbance of the auditory nerve and/or the central nervous system. | ||||||||||||||||||
Treatment | The action or manner of treating an individual, medically or surgically. Medical treatment is the action or manner of treating an individual, medically or surgically by a physician. Treatment may include modalities recommended by a health care provider. | ||||||||||||||||||
