Theoretically, one could measure food energy in different ways, using (say) the Gibbs free energy of combustion, or the amount of ATP generated by metabolizing the food. However, the convention is to use the heat of the oxidation reaction, with the water substance produced being in the liquid phase.
A specialized form of VRT is available to treat benign paroxysmal positional vertigo (BPPV). This treatment is often referred to as the Epley maneuver, and involves a series of specifically patterned head and trunk movements to move tiny displaced otoliths to a place in the inner ear where they canât cause symptoms.
Some cases of vertigo improve over time, without treatment. However, some people have repeated episodes for many months, or even years, such as those with MÃ©niÃ¨re's disease. There are specific treatments for some causes of vertigo. A series of simple head movements (known as the Epley manoeuvre) is used to treat BPPV.
