Infrared Therapy

The document discusses infrared therapy (IRT), including its sources, classification, physiological effects, therapeutic effects, dangers, technique of application, dosage, and contraindications. IRT uses infrared radiation to provide superficial heating that increases local temperature, metabolism, blood flow, and other physiological effects. Common applications of IRT include relief of pain and muscle relaxation by accelerating healing. Precautions must be taken to avoid burns and other dangers when applying IRT.

Introduction of IRT • IR rays are electromagnetic waves • It lies between visible light and microwaves • Wavelength is about 750nm to 400000 nm • Frequency is 4x 1014 and 7.4x 1011 • Infrared is superficial Heating modality (penetration depth 1- 10mm). • Infrared is radiant heat transmits energy by radiation. 14/05/2020 IR Therapy (Dr Akshay Shetty) 4

Physiological effects of IRT Increases • Local temperature superficially • Local metabolism • Capillary permeability and blood flow • Lymphatic and venous drainage • Vasodilatation of arterioles and capillaries • Leukocytes& phagocytes activity • Axon reflex activity • Stimulation of sensory nerve 14/05/2020 IR Therapy (Dr Akshay Shetty) 8
Therapeutic effects of IRT • Relief of pain • Muscle relaxation • Increases blood supply • Increases joint mobility • Acceleration of healing & repair 14/05/2020 IR Therapy (Dr Akshay Shetty) 9
Dangers of IRT • Burns • Electric shock • Fatigue • Giddiness • Headache • Gangrene • Injury to eyes • Dehydration 14/05/2020 IR Therapy (Dr Akshay Shetty) 10
Technique of application of IRT Patient position In a suitable well supported position with the area to be treated exposed. Explanation Explain the nature & effects of the treatment to the patient Examination Examine the skin to be heated & test the thermal sensation ,check for contraindications . 14/05/2020 IR Therapy (Dr Akshay Shetty) 11
Contd… Apparatus Non luminous generator takes some time to get heated so they should be switched on before 5 to 7 minutes. Luminous generator needs no warm up time and can be switched on once the patient is ready for the treatment. 14/05/2020 IR Therapy (Dr Akshay Shetty) 12
Contd,.. Arrangement of the lamp & patient Expose the skin to be irradiated and cover or shield the eyes Lamp is positioned opposite to treatment area such that the rays strike the skin at right angle. Set the lamp at an app. Distance which is usually 50-75 cms Instructions & warnings The patient is warned that he should experience comfortable warmth. The patient should report immediately if the heating becomes excessive The patient should not touch any part of the lamp or to move near to it. 14/05/2020 IR Therapy (Dr Akshay Shetty) 13
Contd.. Application At the commencement of the treatment the intensity of the radiation should be low but after 5 to 10 mins strength of the radiation can be increased. The physiotherapist must be near the patient throughout the procedure. Sweating is encouraged 14/05/2020 IR Therapy (Dr Akshay Shetty) 14
Contd.. 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. 14/05/2020 IR Therapy (Dr Akshay Shetty) 15
Dosage of IRT For acute cases 10-15 mins daily for 1-3 mins as per requirement For chronic cases up to 30 mins once or on alternate days 14/05/2020 IR Therapy (Dr Akshay Shetty) 16
Contraindications of IRT • Acute inflammatory conditions • Impaired cutaneous thermal sensation and circulation • Peripheral vascular disease Markedly loss of consciousness. • Acute skin disease, e.g., dermatitis or eczema • Deep X-ray therapy • Defective blood pressure regulation • Acute febrile illness (Fever) • Tumors of the skin • Hemophilia. • Unreliable and elderly patients. • Never apply heat directly to eyes or the genitals. • Never heat the abdomen during pregnancy (first and last trimester ) 14/05/2020 IR Therapy (Dr Akshay Shetty) 17
