Shortwave Diathermy Therapy

Short wave diathermy benefit for you!!

        Short wave diathermy (SWD) is one of the electrotherapy that used in physiotherapy job , SWD is a high frequency alternating current. Usually the frequency 27,120,000 cycle persecond and it wavelength is 11 meter, provide deep heating tissue. This machine is set up like this for the medical purpose.

How does SWD work to our body?

          SWD can produce electromagnetic wave  and electro static current that produce rapid vibration of ion and molecule in tissue and causing heating in tissue. The rapid vibration cause  dipolar molecule  to rotate and non-polar molecule being distortion, this process causing a flow of current in tissue that rich in electrolytes.

See what happen SWD activity at molecular level…..

          When at molecular level, our blood vessel and muscle is being heated strongly. Adipose tissue give out poor heat rate and our fat give out high temperature, however in our body fibrous tissue is not rich in blood vessel or fat, so it will produce moderate heating(comfortable).  Thus is will increase the enzyme  activity and

metabolic rate and also growth.

What can SWD do for us???

1.       Reduce pain

2.     Derease muscle spasm

3.     Resolution of inflammation

4.    Faster the healing process

5.     Control chronic infection

6.    Increase extenbility of the fibrous tissue

7.     Increase blood flow

8.     Increase circulation

9.    Vasodilatation(widening blood vessel)

10. Reduce muscle tone

11.    Increase muscle properties

What SWD do to pain and muscle spasm to treat it??

          SWD can be used to reduce pain by triggering other pain to block the transmission of pain by sent the pain to the ‘pain gate’,

This act called counter irritant, it also reduce other pain. SWD also provide heating to ease pain by promoting vasodilatation.

          SWD also help to treat muscle spasm by heating directly to the muscle spindle as the temperature of muscle spindle increase , it will convey muscle to relax, golgi tendon organ also help n preventing muscle to over-strech.

SWD also can increase connective tissue and joint range….

          As the temperature of connective tissue or joint rise at therapeutic range and cause the collagen become more plastic and less elastic. This show that connective tissue can be elongated when at 45  and return at new length than stretch at 25  , the effect is can do long stretch with minimum force, greatest elongation and less pain, and maximum recovery.
