Question

Research a common modality that is used in rehabilitation.

1. How does Ultrasound work? NOT the ultrasound that produces an image such as is done to look at a fetus/baby in the womb.

2. What are the common injuries or conditions that Ultrasound is used for?

3. Are there any contraindications that would prevent the use of Ultrasound?

Answer 1

ANS)

* The ultrasound device transfer large frequency sound vibrations to the human body with the help of probe.

Usually the vibration of the sound move to the body and strike a border among tissues.

But little sound vibrations will bounce back towards the probe itself and at the same time some sound vibrations move forward till they stick out to another border.

The vibrations which came back are taken by probe and pass into the device.

After that the device will clearly compute the farness of probe to group of cells(tissues) with the help of velocity of sound waves in the group of cells and the duration of every echo's come back.

After that the device will show the farness and strength of echoes in its monitor,making a 2 dimensional picture.

* The usual situations in which the ultrasound treatment is preferred are soft tissue damages like the inflammation of tendon,bump in joints and muscle convulsion.

* The ultrasound is not allowed to perform in cancerous regions,because that might enhance the possibility of metastasis.

The usage of ultrasound close to eyes will harm the retina of eye.

The usage of ultrasound in the bones of young individuals will leads to breaking of bones and difficulties in regions of bones which accountable for development.

The ultrasound should not be used in regions surrounding the heart because,it may make changes to electrical impulse surrounding the heart.
