Ultrasound Parameters UNFINISHED

Question 1

Frequency for deeper tissues, muscles, & most joints?

Answer 1

1 MHz

Question 2

Frequncy for superficial tissues, small muscles, most tendons, and small joints?

Answer 2

3 MHz

Question 3

Continuous mode uses?

Answer 3

heating effects and pain

Question 4

Pulsed mode uses?

Answer 4

tissue and bone healing
maybe swelling

Question 5

Intensity to heat tissues?

Answer 5

at 1 MHz: 1.0-2.0 w/cm^2
at 3 MHz: 0.5 w/cm^2 will produce heat if continuous mode
Deeper tissues require higher intensity
Superficial tissues requires lower intensity

Question 6

Duration general rule?

Answer 6

5-10 min for 2x the size of the ERA

Question 7

Thermal ultrasound clinical application?

Answer 7

prior to stretching or mobilization
reduction of pain

Question 8

Nonthermal ultrasound clinical application

Answer 8

altering cell membrane permeability
accelerate tissue healing (dermal ulcers, surgical skin incisions, tendon injuries, bone fractures)

Question 9

Ultrasound for soft tissue extensibility clinical application

Answer 9

by warming up tissues
altering viscoelasticity of collagen and alteration of the collagen matrix

Question 10

Ultrasound for pain control clinical application

Answer 10

altering transmission or perception
decrease pain by heating up/healing tissue
