stop consecutive ultrasound treatment after _______ weeks and monitor for ______ weeks | 12-15 2 |
coupling medium | needed for ultrasound to transmit ultrasound |
phonophoresis | the use of ultrasound to drive molecules of a drug or substance through the skin to underlying tissues |
how does ultrasound work? (part 1) | an electrical current travels down and until it hits the sound head where there is a synthetic crystal. when it hits, the crystal deforms from cycles of compression (short and thick) to rarefaction (long and thin) resulting in ultrasonic waves. |
how does ultrasound work? (part 2) | when the sound waves leave the crystal they initially run parallel. this is known as the Fresnel zone. when they split it is known as the fraunhofer zone. the waves hitting the molecules in the body causes causes them to vibrate and produce heat |
usual frequency of ultrasound | 1 MHz and 3 MHz |
frequency of ultrasound controls... | the frequency of the sound waves transmitted and the depth of sound wave penetration |
3 MHz ultrasound waves are used for... | superficial tissues |
Electric stimulation levels of stimulation | subsensory sensory motor noxious |
with heat treatment, blood viscosity... | decreases |
local effects of heat treatment (part 1) | vasodilation increases in: cell metabolism delivery of leukocytes cell permeability venus return, lymphatic drainage elasticity of muscles, ligaments, capsules analgesia, relaxation, nerve conduction |
local effects of heat treatment (part 2) | edema formation metabolic waste removal increased nerve conduction reduced joint stiffness perspiration |
trauma causes: (on the therapeutic modalities slide about cryotherapy physiological effects) | pain inflammation dysfunction spasm local ischemia |
circulatory effects of cryotherapy | vasoconstriction followed by slight period of vasodilation (temp increase) known as hunting response. thought to take place as body's defense against tissue death from too much cold. |
