The first publication to document a change in pain perception associated with the weather was the American Journal of the Medical Sciences in 1887. This involved a single case report describing a person with phantom limb pain, and it concluded that "approaching storms, dropping barometric pressure and rain were associated with increased pain complaint."
Underwater diving is the most frequently cited example, but pressure changes also affect people who work in other pressurized environments (for example, caisson workers), and people who move between different altitudes. A dysbaric disorder may be acute or chronic.
Atmospheric pressure, also known as air pressure or barometric pressure (after the barometer), is the pressure within the atmosphere of Earth. The standard atmosphere (symbol: atm) is a unit of pressure defined as 101,325 Pa (1,013.25 hPa ), which is equivalent to 1,013.25 millibars , [ 1 ] 760 mm Hg , 29.9212 inches Hg , or 14.696 psi .

Barotrauma is physical damage to body tissues caused by a difference in pressure between a gas space inside, or in contact with, the body and the surrounding gas or liquid. [1] [2] The initial damage is usually due to over-stretching the tissues in tension or shear, either directly by an expansion of the gas in the closed space or by pressure difference hydrostatically transmitted through the ...
The physics that affect the body in the sky or in space are different from the ground. For example, barometric pressure is different at different heights. At sea level barometric pressure is 760 mmHg; at 3,048 m above sea level, barometric pressure is 523 mmHg, and at 15,240 m, the barometric pressure is 87 mmHg.

While this ruling did not directly affect the disability community, it ruled segregation in schools as unconstitutional, making a start to the inclusion of all students in the classroom.
