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.
Signs and Symptoms of Vertigo. Vertigo, or dizziness, refers to the sensation of spinning (subjective vertigo) or the perception that surrounding objects are moving or spinning (objective vertigo). Some patients describe a feeling of being pulled toward the floor or toward one side of the room. Moving the head, changing position, and turning while lying down often worsen vertigo. The sudden onset of vertigo usually indicates a peripheral vestibular disorder (inner ear disturbance; e.g., BPPV, MÃ©niÃ¨re disease, vestibular neuritis, labyrinthitis).
