Study Notes
Infrared Radiation Therapy (IR)
- Superficial thermal agent applied to treat pain and stiffness, increase joint motion, and enhance healing of soft tissue lesions and skin conditions.
- IR is a form of electromagnetic radiation that produces heat when absorbed by matter.
- Sources of IR can be natural (e.g., the sun) or artificial (e.g., radiant heaters).
Infrared Physical Characteristics
- IR is classified into three bands based on wavelength and penetration depth: IRA (short/near IR), IRB (long/far IR), and IRC (not used therapeutically).
- IRA penetrates up to 5 mm into the dermis, while IRB penetrates up to 1 mm into the epidermis.
- The wavelength of IR emitted depends on the temperature of the material.
Sources of Infrared
- Artificial sources of IR include luminous (e.g., electric light bulbs) and non-luminous sources (e.g., moist heat packs).
- Luminous sources emit IRA, visible light, and ultraviolet radiation.
- Non-luminous sources emit primarily IRB radiation.
Physiological effects of Infrared
- Cutaneous vasodilatation: IR leads to vasodilatation due to histamine release and axon reflex mechanisms, causing increased blood flow in the cutaneous circulation.
- Increased metabolism: IR elevates the temperature of superficial tissues, leading to increased metabolic activity which improves cell function and healing.
- Neurological effects: IR can relieve pain by stimulating sensory nerves (A-beta nerve fibers), inhibiting pain at the spinal cord level, decreasing muscle spindle activity for muscle relaxation, removing waste products through improved circulation, and increasing venous return.
- Connective tissue effects: IR increases the extensibility of connective tissue, making it beneficial for improving range of motion (ROM) in conjunction with stretching and mobilization exercises.
IR Indications
- Pain
- Muscle spasm
- Incisional wounds (accelerates healing)
- Subacute and chronic musculoskeletal inflammation
- Chronic mild to moderate edema
- Prior to stretching and mobilizing exercises
- Some skin conditions (e.g., fungal infection)
IR Contraindications
- Acute inflammation
- Acute infection
- Open wounds
- Impaired sensation
- Impaired circulation
- Over the pregnant uterus
- Eyes
- Metal
IR Hazards and Dangers
- Burns: High temperature IR can cause burns, particularly if the patient is unaware of the heat level or unable to communicate.
- Eye damage: The eyes should be protected during IR therapy to prevent dryness or irritation.
- Lowered blood pressure: IR can cause a decrease in blood pressure.
