Diathermy is a form of physical therapy in which deep heating of tissues is accomplished by the use of high-frequency electrical current It is invented by an American engineer Nikola Tesla in 1891who first noted that heat resulted from irradiation of tissue with high-frequency alternating current .
Diathermy is a therapeutic treatment most commonly prescribed for muscle and joint conditions. It uses a high-frequency electric current to stimulate heat generation within body tissues.
The heat can help with various processes, including:
- increasing blood flow
- relieving pain
- improving the mobility of tissues as they heal
Diathermy Machines Manufacturers for different type of Diathermy .There are three main types of diathermy: shortwave, microwave, and ultrasound.
Shortwave– uses high-frequency electromagnetic energy to generate heat. It may be applied in pulsed or continuous energy waves. It has been used to treat pain from kidney stones, and pelvic inflammatory disease.
Microwave–Microwave diathermy uses microwaves to generate heat in the body. It can be used to evenly warm deep tissues without heating the skin.
Ultrasound-Ultrasound diathermy uses sound waves to treat deep tissues. Heat is generated by the vibration of the tissue. This promotes blood flow into the area. Ultrasound diathermy is used for:
- musculoskeletal sprains
- muscle spasms
- joint contractures or adhesions
How does diathermy work?–
Diathermy uses high-frequency electric current to produce heat deep inside a targeted tissue. It can reach areas as deep as two inches beneath the skin’s surface.
The diathermy machine does not apply heat directly to the body. Instead, the waves generated by the machine allow the body to generate heat from within the targeted tissue.
Diathermy is usually part of a complete physical therapy or rehabilitative regimen. Frequency and length of treatments vary.
What are the benefits of diathermy?–Treating injuries with heat can increase the blood flow and make connective tissue more flexible. It can also help minimize inflammation and reduce the incidence of edema, or fluid retention.
By increasing the blood flow to the site of an injury, the deep heat generated with diathermy can accelerate healing.
Diathermy is used to treat the following conditions:
- arthritis, back pain ,fibromyalgia ,muscle spasms ,myositis neuralgia sprains and strains and tendonitis
What are the risks of diathermy?-The electromagnetic energy used in shortwave and microwave diathermy can cause extreme heat in metal devices such as: bone pins , dental fillings and metal sutures
This could cause burns in the tissue near the implant. The procedure should not be used over these areas to avoid the risk of burning.
During diathermy treatment, you become a part of the electrical field. Touching a bare metal object, including a metal part of the diathermy cabinet, can cause a shock or burn.
Diathermy should be avoided over open growth plates in children.
Conclusion – There are large number of Diathermy Machines Manufacturers are available in the market. One should be particular about the quality and Best Diathermy Machine Price before purchasing
