1 Infra Red Therapy

2 Electromagnetic spectrum
A spectrum is an arrangement of rays in order of their wave length. (It is the distance between point on one electromagnetic wave to exactly the same point on the next wave).

3 Electromagnetic radiation
Gamma Rays Light with the shortest wavelengths and the highest energies and frequencies in the electromagnetic spectrum; also called gamma radiation. X-Rays Electromagnetic radiation with very short wavelengths and very high energies and frequencies. X-rays fall between gamma rays and ultraviolet radiation Ultraviolet Electromagnetic radiation with shorter wavelengths and higher energies and frequencies than visible light. UV light is lower in frequency than X-rays. Visible Light The part of the electromagnetic spectrum that human eyes can detect; also known as the visible spectrum. The colors of the rainbow make up visible light. Blue light has more energy than red light. Infrared Radiation that has longer wavelengths and lower frequencies and energies than visible light. Radio Waves Radiation with the longest wavelengths and smallest frequencies and energies in the electromagnetic spectrum.

4 What is Infra Red Radiation?
Electro magnetic waves with wave lengths of 750nm – 400,000nm any hot body emits infra red waves The sun, gas fire, coal fires, electric fields, hot, water pipes etc. are some of the sources

5 Various types of infra red generators are employed in physiotherapy departments
There are two main groups 1. non luminous provide infra red rays only 2. luminous emits visible and few ultra violet rays as well as infra red Treatment with luminous generator is often refried as radiant heat The term infra red is generally applied to radiation from non luminous surces

7 Choice of apparatus In many cases luminous and non luminous generators are equally suitable But in some instances one becomes more satisfactory than others When there is acute inflammation or recent injury, the sedative effects of the rays obtained from non luminous generator may prove more effective for relieving pain than counter irritant effect of those from luminous source For lesions of more chronic type the counter irritant effect of the shorter rays may prove to be value & there fore luminous generator is chosen

9 Arrangement of the lamp and the patient
The lamp is positioned so that it is opposite to the centre of the are to be treated Rays should strike the skin at right angles Maximum absorption should be ensured Distance of the patient from the lamp should be measured It is usually 75 to 50cm It depends on the output of the generator Care must be taken that the patient’s face is not exposed to the IR rays The eyes must be shielded if it is not possible to avoid irradiating the face

10 Therapeutic Effects Relieving pain Muscle relaxation
Increasing blood supply

11 Dangers Burn Burs may be caused by following reasons
If intensity of radiation is to high If sensation is not proper Patient fails to report over heating Unconscious patient Patient moves closer to the lamp Falls asleep during treatment Electric shock Faintness or giddiness Headache Gangrene Injury to eyes

12 Contraindications Defective arterial blood supply
Areas where there is danger of hemorrhage Defective skin sensation Directly over the eyes After deep x-ray or Cobalt therapy Known cases of tumors
