SWD is contraindicated in areas with metal implants and in patients with pacemakers or implanted deep brain stimulators.
What diathermy means?
Diathermy is a treatment option that uses energy sources to deep heat areas of your body. Rather than a heat source, diathermy uses sources like sound and electricity, which are converted into heat by your body. Diathermy, also called “deep heating,” heats deep below the surface of your skin.

Diathermy. Diathermy refers to the use of electrically induced heat to cut, destroy, or coagulate tissue. Though more commonly utilized in physical and occupational therapy to treat injuries and relax muscles, the approach can be used in urologic surgery.
Can diathermy burns be dangerous?
Diathermy burns can occur if proper precautions are not taken. If the diathermy pad is not making complete contact with the patient, the electrical current searches for a way to contact earth and if it is touched, it can be dangerously hot.
Can diathermy cause smoke?
A surgical procedure utilizing diathermy can generate smoke. This smoke may be harmful since it can contain chemical by-products, carbonized tissue, blood particles, viral DNA particles, infectious viruses, or bacteria. These can be absorbed by the lungs or skin, which may cause damage if masks are not worn and proper smoke filtration systems are not used.
What is the purpose of diathermy?
Diathermy is commonly used for muscle relaxation, and to induce deep heating in tissue for therapeutic purposes in medicine . It is used in physical therapy to deliver moderate heat directly to pathologic lesions in the deeper tissues of the body.
How does diathermy work?
Short wave diathermy machines use two condenser plates that are placed on either side of the body part to be treated. Another mode of application is by induction coils that are pliable and can be molded to fit the part of the body under treatment. As the high-frequency waves travel through the body tissues between the condensers or the coils, they are converted into heat. The degree of heat and depth of penetration depend in part on the absorptive and resistance properties of the tissues that the waves encounter.
What frequency is diathermy?
Diathermy is produced by three techniques: ultrasound ( ultrasonic diathermy ), short-wave radio frequencies in the range 1–100 MHz ( shortwave diathermy) or microwaves typically in the 915 MHz or 2.45 GHz bands ( microwave diathermy ), the methods differing mainly in their penetration capability. It exerts physical effects ...

Short wave diathermy usually is prescribed for treatment of deep muscles and joints that are covered with a heavy soft-tissue mass , for example, the hip. In some instances short wave diathermy may be applied to localize deep inflammatory processes, as in pelvic inflammatory disease.
What is ultrasound diathermy?
Ultrasound diathermy employs high-frequency acoustic vibrations which, when propelled through the tissues, are converted into heat. This type of diathermy is especially useful in the delivery of heat to selected musculatures and structures because there is a difference in the sensitivity of various fibers to the acoustic vibrations; some are more absorptive and some are more reflective. For example, in subcutaneous fat, relatively little energy is converted into heat, but in muscle tissues there is a much higher rate of conversion to heat.

How does pulsed R.F. diathermy produce heat?
Any physiological responses produced by pulsed r.f. diathermy are attributable to heat produced by the average power output. Microwave diathermy produces heat in the body tissues through application of microwave energy to the concerned area. The microwave energy stimulates tissue molecules, as r.f.
What is the purpose of an ultrasonic applicator?
The ultrasonic applicator is then brought in contact with the cream which acts as a coupling medium for the ultrasonic energy between the transducer and the body. For an irregular surface such as a hand or foot, the limb and the applicator are immersed in water which readily transmits the energy to the tissues.
What is ultrasonic diathermy?
Ultrasonic diathermy is intended to generate deep heat within body tissues for the treatment of selected medical conditions such as pain, muscle spasms and joint contractures, but not for the treatment of malignancies. The sound waves are transmitted through a round-headed wand that the therapist applies to the skin with gentle, circular movements.

Over the years, FDA has evaluated a number of ultrasonic diathermy devices. They are all capable of heating deep tissue to a therapeutic temperature range of 40-45°C for the selected conditions described above. However, there are various configurations with regard to energy output and applicator size. Furthermore, there may be instructions that apply only to a particular device. Therefore, it is important that you read and be familiar with the instructions for the particular device that you use. You should also be especially mindful of all contraindications, warnings, and precautions that apply to the device.

Typically, these devices will claim to treat a range of diseases, disorders, and have other uses that are not covered in the description above (for example, to reduce wrinkles on the face).
Why is the diathermal wall important?
In thermodynamics, a diathermal wall between two thermodynamic systems allows heat transfer but do not allow transfer of matter across it. The diathermal wall is important because, in thermodynamics, it is customary to assume a priori, for a closed system , the physical existence of transfer of energy across a wall that is impermeable to matter ...
What is Buchdahl's theory of diathermal walls?
Nevertheless, Carathéodory explicitly postulates the existence of walls that are permeable only to heat, that is to say impermeable to work and to matter, but still permeable to energy in some unspecified way; they are called diathermal walls.
What is heat transfer?
In the mechanical stream of thinking about closed systems, heat transferred is defined as a calculated residual amount of energy transferred after the energy transferred as work has been determined, assuming for the calculation the law of conservation of energy, without reference to the concept of temperature. There are five main elements of the underlying theory.
Can diathermal walls move?
Accounts of the diathermal wall. As mentioned above, a diathermal wall may pass energy as heat by thermal conduction, but not the matter. A diathermal wall can move and thus be a part of a transfer of energy as work. Amongst walls that are impermeable to matter, diathermal and adiabatic walls are contraries.
What is diathermy in beauty culture?
When the term diathermy is used in Beauty Culture it usually refers to ‘surgical diathermy’. Diathermy treatments of this type – also known a thermolysis – were used from the 1930s onwards in Beauty Culture as an alternative to electrolysis for the permanent removal of superfluous hair, spider veins (telangiectasia), acne, warts, moles and other skin blemishes.

Diathermy. The story of diathermy began in 1892 when Doctor Jacques Arsène d’Arsonval demonstrated that a high-frequency electric current could pass through a person’s body without electrocuting them, the only sensation being that of warmth (Cumberbatch, 1937, p. 13). Further experiments by d’Arsonval and others led to the use ...
What is the term for the process of heating tissues that generates heat?
The medical profession generally refers to diathermy that generates heat intense enough to desiccate or coagulate body tissues – used in surgery as an alternative to a knife or scalpel – as ‘surgical diathermy’ to distinguish it from ‘medical diathermy’ which gently warms the tissues rather than destroying them.

1930 A man having a diathermy heat treatment on the frontal cortex of his brain. 1933 Surgical diathermy treatment, possibly for pimples or acne. High-frequency diathermy could be replaced with a simple heating pad. This mask appears to be a Thera Therm Electro-Velour face mask.
Does diathermy help with cellulite?
Although there are some salons today that offer warming diathermy treatments as a ‘circulation booster’ during a facial, these are not typical. A more common and more recent use of ‘medical diathermy’ in Beauty Culture has been in cellulite treatments. Although it is generally combined with other procedures rather than used in isolation, the deep heat produced by diathermy has been claimed to enhance collagen production; increase blood circulation through vasodilation; improve lymphatic drainage of trapped fatty deposits; and even break down fat cells.
