What is continuous shortwave diathermy?
Continuous shortwave diathermy is the technique of choice when uniform marked elevation of temperature is required in the deep tissues. This heating can be targeted accurately by using an appropriate applicator positioned correctly.
What is pulsed shortwave diathermy?
Pulsed Shortwave diathermy (PSWD) uses high-frequency electromagnetic current to promote tissue healing and ease pain. This type of therapy has thermal (mild heating) and non-thermal effects and is effective at treating muscles, nerves, and areas of swelling.
Is short wave diathermy effective?
Limitations due to pain in work-related and non-work-related activities decreased (p < 0.01); use of pain medications was reduced at T1 vs T0 (p < 0.01). Our results suggest that SWD is effective in reducing musculoskeletal pain in the short term, providing relief and improving quality of life.
What are techniques of application of SWD?
The application of SWD was performed in four steps: SWD with the power off and knee in extension; SWD with the power on and knee in extension; SWD with power off and 90° of knee flexion; and SWD with power on and 90° of knee flexion.
How often and how long duration shortwave diathermy can be applied to the patients?
Treatment duration: Usually from five to 20 minutes depending on indications and dosage. Treatments can be done on daily or every other day. The traditional course of treatments consists of 15 to 20 sessions and can be repeated after one week.
What is the difference between pulsed and continuous ultrasound?
Continuous US (CUS) generates thermal effects by stimulating the process of tissue regeneration, changing cell membrane permeability and increasing intracellular calcium, while pulsed US (PUS) mainly produces non-thermal effects to increase tissue metabolism, enhance fibrous tissue extensibility and elevate pain …
What is the difference between SWD and MWD?
Shortwave diathermy converts non-ionizing radiation (radio waves) between 10 and 100 MHz, with a commonly used frequency at 2712 MHz, to deep-heat tissue. Microwave diathermy uses non-ionizing electromagnetic radiation between 300 and 300,000 MHz with a commonly used frequency of 2450 MHz.
When do you use shortwave diathermy?
“Shortwave diathermy 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. It’s commonly used for conditions that cause pain and muscle spasms.”
What are the types of shortwave diathermy?
Respectively, there are two methods of the shortwave diathermy: Condenser shortwave diathermy (high-frequency electrical field) Induction shortwave diathermy (high-frequency magnetic field)
What are the two methods of short wave diathermy?
When do you use pulsed ultrasound?
Medical uses As of 2012 it was being studied for dental problems. Low intensity pulsed ultrasound has been proposed as a therapy to support bone healing after fractures, osteomies, or delayed healing.
Can pulsed shortwave diathermy be used over surgically implanted metal?
Can Pulsed Shortwave Diathermy be Used Over Surgically-Implanted Metal? Pulsed shortwave diathermy (PSWD) is an electrical-magnetic modality used for generating thermal effects in tissues. Contemporary practice recommendations indicate PSWD should not be used over tissues surrounding surgically-implanted metal.
What is IRR in physiotherapy?
Introduction. Infrared (IR) or thermal radiation is a band of energy in the complete electromagnetic spectrum. IR are the radiations of longer wavelength than the red end of the visible spectrum and extend to the microwave region, i.e., from 760 nm to 1 mm. IR radiation is generated by Sun.
What is the difference between shortwave and microwave diathermy?
Microwave diathermy, seldom used in the United States, uses high-frequency electromagnetic waves (2450 MHz; wavelength of 11 m) to heat tissues. Short- wave diathermy uses high-frequency electromagnetic waves that are similar to radio waves (10–100 MHz) to heat deep tissues.
