What is diathermy?
In medicine, diathermy uses high-frequency electromagnetic fields applied to the body’s tissues with the aim of increasing tissue temperature and consequently inducing various therapeutic effects.
Our devices — dVinci, dVET, and dVina — generate an alternating current with frequencies ranging from 0.8 MHz to 1.2 MHz. Through the pair of electrodes supplied, energy is transferred to the patient’s tissues, effectively making the patient part of the electrical circuit.
In the presence of pathological or traumatic conditions, normal tissue physiological activity may be altered. By delivering energy to the tissues, diathermy supports the biological processes involved in functional recovery.
The application of high-frequency currents induces the movement of electrical charges within the tissues. Capacitive and resistive electrodes allow modulation of energy transfer according to the characteristics of different anatomical areas.
The displacement currents generated by the electromagnetic field facilitate energy transfer within the tissues, contributing to the biological and thermal effects associated with the treatment.
During the treatment, the patient generally experiences a pleasant sensation of deep warmth.
Why is diathermy effective?
Diathermy employs high-frequency electrical currents which, at the therapeutic intensities used, do not produce the neuromuscular stimulation typically associated with lower frequencies, such as those used in electrical stimulation therapies. The energy transferred to the tissues is converted into heat, generating a controlled thermal effect that is generally well tolerated by patients. As a result, diathermy represents a valuable adjunct to physiotherapy and rehabilitation programs, supporting treatment objectives within the framework established by the healthcare professional.
For this reason, since the 1980s, Capacitive and Resistive Diathermy technologies have experienced significant development, achieving high levels of clinical satisfaction among both healthcare professionals and patients.
The use of heat in therapeutic treatments increases local blood flow, enhancing the delivery of nutrients and oxygen to the cells while facilitating the removal of metabolic waste products. Heat may support the physiological processes involved in the resorption of hematomas and can contribute to pain reduction in chronic, traumatic, and inflammatory conditions. For this reason, it is widely incorporated into physiotherapy and rehabilitation programs as part of a comprehensive therapeutic approach.
EFFECTS OF OUR DEVICES
Effects at a tissue level: the increase in temperature generates an increase in local blood flow, which increases the supply of oxygen and nutrients, as well as speeding up the outflow of waste substances.
Effects at extracellular matrix level: the energy transferred to the tissues may interact with physiological processes involving the extracellular matrix, contributing to the maintenance of an environment conducive to metabolic exchange and tissue repair processes.
Effects at cell level: diathermy may support cellular metabolic processes and the biological mechanisms involved in functional tissue recovery, promoting a physiological environment conducive to tissue repair and remodelling.
AUTOMATIC
The automatic mode, enabled through dedicated treatment plates and, where required, in combination with the handpiece, allows the treatment of large anatomical areas without the need for continuous manual application.
This solution has been designed to enhance clinical workflow efficiency and optimize treatment time management, while always ensuring professional supervision throughout the therapy session.
ROLL-ON
The patented ergonomic Roll-On handpiece enables the combination of diathermy treatment with the application of topical products, promoting their even distribution across the treated area while enhancing operator comfort and ease of use.
BIPOLAR
Thanks to its bipolar configuration, treatment can be performed using the handpiece alone, without the need for a return electrode. This solution provides excellent operational flexibility for localized applications and for treating anatomical areas that are more difficult to manage with conventional electrodes.
TWO CHANNELS
Dual-channel technology allows two different anatomical areas to be treated simultaneously, enhancing operational efficiency and maximizing treatment flexibility. Each channel can be independently configured and operated in either automatic or manual mode, providing exceptional versatility across a wide range of clinical applications.
