Energy Flashcards
a form of therapy used in rehabilitation that produces a change in soft tissue through light, water, temperature, sound, or electricity.
electrophysical agent
the capacity of a system for doing work or its equivalent in the strict physical sense
energy
process by which energy of various forms travels through space
radiant energy
which theory states “ the higher the frequency, the higher the photon energy”
quantum theory
which theory states “ energy is transmitted by oscillatory motion in the form of electromagnetic waves. The shorter the wavelength the higher the frequency”
electromagnetic wave theory
the energy absorbed must be sufficient so as to stimulate the absorbing tissues (what principle?)
Arndt-Schultz Principle
what temperature is necessary to achieve muscle elongation?
4 degrees Celsius
if energy is not absorbed by the superficial tissue, then it will penetrate to deeper tissues (what law?)
Law of Grotthus-Draper
the maximum amount of absorption of radiant energy occurs when the source is at right angles to the absorbing surface (what law?)
cosine law
the intensity of the radiation striking the surface varies inversely with the square of the distance from the source (what law?)
inverse square law
the intensity and duration of the does of radiant energy are inversely proportional (what law?)
Bunsen Roscoe Law of Reciprocity
two types of acoustic modalities?
therapeutic ultrasound and ponophoresis
two types of mechanical modalities?
mechanical traction and compression
