IR rays produced by Luminous generators can penetrate into dermis and epidermis. IR rays produced by Non-luminous generators can penetrate the superficial dermis only. Penetration of energy into a medium is depended upon : a) Intensity of the source of infrared b) Wavelength and frequency c) Angle at which the radiation hits the surface d) Coefficient of absorption of the material.

PRESENTATION

2. INTRODUCTION
Infrared rays are electromagnetic waves.
It lies between visible light and microwaves.
Wavelength: 750 nm to 400000 nm.
Frequency: 4×1014 Hz and 7.5×1011 Hz.

3. Types IR Lamps
Two types of infrared sources are used in
physiotherapy practice:
Non-luminous
generators

4. PENETRATION
IR rays produced by Luminous generators can
penetrate into dermis and epidermis.
IR rays produced by Non-luminous generators
can penetrate the superficial dermis only.
Penetration of energy into a medium is
depended upon :
a) Intensity of the source of infrared
b) Wavelength and frequency
c) Angle at which the radiation hits the surface
d) Coefficient of absorption of the material.

5. Technique of application
Patient position: Position the patient in a suitable, well supported position
with the area to be treated exposed.
 Explanation: Explain the nature and effects of the treatment to the patient.
 Examination: examine the skin to be treated and test the thermal sensation
and also check for contraindication

6. Physiotherapist preparation
 Non-luminous generators take some time to get heated, so they
should be switched on before 5-7 min of treatment.
 Maintain a safe distance from the lamp.
 Keep the eyes safe from the ray.
 Check if there is any contra indication on patient skin.
 Always take concern from the patient.
 Always keep eye on patients condition if there is any discomfort
feeling or excessive temp. on the area.

7. patient preparation
Expose the skin to be irradiated and cover or shield the eyes.
The lamp is positioned opposite to the treatment area such that
rays strike the skin at right angles.
Set the lamp at an appropriate distance which is usually 45-75 cm.
Remove cloth from treatment area.
Switch on lamp for 10-20 min depending on surface area.

8. INSTRUCTION AND WARNING
 The patient is warned that he should experience
comfortable warmth.
 Patient should report immediately if the heating becomes
excessive.
 Patient should not touch any part of the lamp or to move
nearer to it.

9. TERMINATION
 On completion of the treatment the skin should be
checked carefully.
 On palpation it may feel mildly or moderately warm and a
moderate erythema should be evident.
 After extensive irradiation the patient should not rise
suddenly from the recumbent position or go out in cold
therapy.

10. DOSAGE
 For acute cases irradiation with infra-red rays can be
given for 10 to 15 minutes daily for 1 to 3 times as
per the requirement.
 For chronic cases upto 30 minutes once (daily) or on
alternate days can be given.
