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
Acute phase
4 to 7 to 10 days
Redness/ swelling/pain/Heat/loss of function
Fibroblastic
Caused by call death, leads to a period of scar formation and repair of injured
Remodeling
Realignment of collagen fibers along lines of tensile force
Wolff’s law
Bone tissue will respond to the physical demands placed on them causing them to remodel along lines of tensile force
Immobilization during the inflammatory
Response phase will facilitate healing by controlling
Iinflammation
Controlled mobilization superior
Decreases scar formation, increase revascularization, facilitates muscle regeneration, reorientation of muscle & ligament fibers.
Progression criteria in controlled mobilization in the remodeling phase
Aggressive passive & than active ROM
Factors that impede healing
Extent of injury, edema, hemorrhage, poor vascular supply, separation of tissue, muscle spasm, atrophy, Corticosteroids, keloids & hypertrophic scar, infection, humidity, climate, age, Health nutritions
