Abstract:
The use of infrared radiation in physiotherapy plays a very important role
to relieve pain by increasing blood flow through tissues and remove waste
products from the targeted area, if it is used in scientific manner for
example the time of duration for exposure as it recommended is 15 to 20
minutes and reach’s 30 minutes in some chronic cases. Also the distance
between the source and the skin surface is in the range of 60cms to
90cms٫ for chronic and acute conditions respectively.
On the other hand the lamp used to produce infrared radiation must be
prepared in a certain specifications e.g. it is power density and it is
efficiency must be known .
By using digital thermometer to measure the temperature and using a
measuring tape to measure the distance between the source and the skin
surface so as to confirm the variation in the factors mentioned above. The
researcher assumes that the source emission is 250 watt as it written on the
lamp for chronic cases٫ the standard distance is 60 cm and for acute cases is
90 cm while the standard time for both is 20 minutes.
The real doses given are different from session to session. Some of them are
under dosed and others over dosed. The researcher worked out the optimum
doses at specified times and distances above and tabulated his findings. He
recommended standard values to proper treatment of acute and chronic
