| runner's condition | <orthopaedics> A condition where the knee cap (patella) rubs on the surface of the femur rather than following its normal tracking over the knee joint. This condition is brought about by stress or overuse (for example runners). Running on hills or incline surfaces can exacerbate this problem. Symptoms include knee pain, just under the knee cap after running, progressing to knee pain at rest. Treatment includes rest and stretching exercises for the quadriceps and hamstring muscles. Strengthening the medial (inner) head of the quadriceps (along the inner thigh) will help pull the knee cap medially and correct the problem. (17 Dec 1997) |

| condition | A mode or state of being, the state of being fit: the physical status of the body as a whole or of one of its parts usually used to indicate abnormality. (18 Nov 1997) |
| sine condition | <microscopy> The design of a lens must fulfill this condition, described by Abbe, if the image is to be aplanatic. It states that the ratio of the sines of the angles of the incident and refracted rays to the axis must be constant, this constant is equal to the inverse of the magnification of the image.

| stoichiometric condition | That condition at which the proportion of the air-to-fuel is such that all combustible products will be completely burned with no oxygen remaining in the combustion air. (05 Dec 1998) |
| desired future condition | A vision of the desired future state of a specific area. A description of land and resource conditions expected to result if management goals and objectives are achieved. (05 Dec 1998) |
| disturbed condition | <ecology> Refers to areas in which indicators of one or more characteristics (vegetation, soil and/or hydrology) have been sufficiently altered by man's activities or natural events so as to make it more difficult to recognise whether or not the wetland identification criteria are met.

| fibrocystic condition of the breast | A benign disease common in women of the third, fourth, and fifth decades characterised by formation, in one or both breasts, of small cysts containing fluid which may appear as blue dome cysts; associated with stromal fibrosis and with variable degrees of intraductal epithelial hyperplasia and sclerosing adenosis. Synonym: cystic hyperplasia of the breast. (05 Mar 2000) |
| air pollutants, environmental | Air pollutants which affect environmental conditions. (12 Dec 1998) |
| carcinogens, environmental | Carcinogenic substances that are found in the environment. (12 Dec 1998) |
| national environmental policy act | A federal law enacted in 1969 that requires all federal agencies to consider and analyse the environmental impacts of any proposed action. NEPA requires an environmental impact statement for major federal actions significantly affecting the quality of the environment. NEPA requires federal agencies to inform and involve the public in the agency's decision making process and to consider the environmental impacts of the agency's decision. (05 Dec 1998) |
| draft environmental impact statement | (DEIS) A draft statement of environmental effects. Section 102 of the National Environmental Policy Act requires a DEIS for all major federal actions. The DEIS is released to the public and other agencies for comment and review. (05 Dec 1998) |
| environmental assessment | (EA) A public document that analyzes a proposed federal action for the possibility of significant environmental impacts. The analysis is required by NEPA. If the environmental impacts will be significant, the federal agency must then prepare an environmental impact statement. (05 Dec 1998) |
| environmental exposure | The exposure to potentially harmful chemical, physical, or biological agents in the environment or to environmental factors that may include ionizing radiation, pathogenic organisms, or toxic chemicals. (12 Dec 1998) |
| environmental health | The science of controlling or modifying those conditions, influences, or forces surrounding man which relate to promoting, establishing, and maintaining health. (12 Dec 1998) |
| environmental illness | A polysymptomatic condition believed by clinical ecologists to result from immune dysregulation induced by common foods, allergens, and chemicals, resulting in various physical and mental disorders. The medical community has remained largely skeptical of the existence of this "disease", given the plethora of symptoms attributed to environmental illness, the lack of reproducible laboratory abnormalities, and the use of unproven therapies to treat the condition.
