Midterm Flashcards
What is energy?
The capacity of motion making heat
What are the types of energy are therapeutic modalities classified
Electro magnetic energy, conductive thermal energy electrical energy, sound energy, mechanical energy
Electromagnetic energy?
Radiant energy that travels/ ex. Diathermy, light therapy
Conductive thermal energy?
Thermal therapy, cyrothermy
Electrical energy
Stem
Sound energy
Ultrasound
Mechanical energy
Traction massage
Radiation
Process by which energy In various forms travels through space
Wave length a frequency
When contacting biological tissue maybe
Reflected, transmitted, refracted, absorb ed
Law of grotthus-Draper
The greater the amount absorbed the less transmitted and the less transmitted and thus the less penetration
Cosine law
The smaller the angle between the propagating radiation and the right angles the less radiation reflected of the greater the absorption
Inverse square law
The intensity of the radiation striking A surface varies inversely with the square of the distance from the source
Therapeutic uses of electrical stimulating currents
Muscle contractions, pain modulation, ion movement, facilitating soft tissue & bone healing
Ultrasound
Mechanical vibration, a sound wave, produced & transformed from high-frequency electrical energy
Stages/phases of healing
Inflammatory/a cute response phase, fibroblastic-repair phase, maturation-remodeling phase
