Radiofrequency Heating/Diathermy

High frequency electromagnetic energy. Not widely used.

Short wave diathermy (SWD) and microwave diathermy (MWD) – both involve the generation of electrostatic or electromagnetic fields  create heat in tissues. Microwave provides more local heating to the tissues and shortwave a more diffuse heating.

Indications:
Shortwave – post acute soft tissue injury
Microwave – post acute soft tissue injury; trigger points

Contraindications:
Infection; acute inflammation; vascular disease; metal implants; impaired skin sensation.

Methods of application:
A large number of commercial devices are available  many different methods of application.

Shortwave – either a condenser plate either side of area to be treated or by an induction coil
