Function

An equivalent circuit

The human body is an electrical conductor.
Every part of the human body and the complete body itself is the equivalent of an impedance (Z).
Tecar therapy: An equivalent circuit
To understand how Doctor Tecar Therapy interacts with biological tissues it is important to highlight that the human body is the equivalent of an electrical circuit made up of a resistor (R) and a condenser (C) in parallel.

Function

Capacitive part...

The capacitive part of the human body is made up of the tissues which are softer and have higher liquid content, such as muscle mass.
Function

...and resistive part

The resistive part of the body is made up of the harder parts with lower liquid content, such as bone, cartilage, joints and major tendons.

What happens when
the tecar current is applied?

Applying the tecar current (alternating sinusoidal current with frequency between 300 kHz and 1.2 MHz) to a part of the human body is the equivalent of applying the tecar current to an impedance – the equivalent of applying the tecar current to an electrical circuit made up of a resistor and a condenser in parallel.
Tecar therapy: What happens when the tecar current is applied?
In Resistive mode, the lower frequency current flows through the resistive parts of the body (bones, ligaments, important tendons etc.). The resistive mode concentrates the energy mainly on the hard tissues, such as joints, ligaments, tendons and bones.
Tecar therapy: Tecar therapy: What happens when the tecar current is applied?
In CApacitive mode, the higher frequency current mainly flows through the capacitive parts of the human body (muscles, etc). The CApacitive mode concentrates the energy mainly on the soft tissues such as muscles and areas with high liquid content.
Function

The insulated plate

The Resistive and CApacitive modes and their ability to concentrate energy in hard and soft tissues respectively depend on the frequency of the tecar current and not on the use of a different type of plate. The insulated plate is covered in a suitable material which does not increase impedance. The flow of the tecar current through the insulated plate causes an increase in the temperature of the plate which is proportional to the thickness of the coating and which depends on the type of insulation used. – changes the thermal sensation on the surface of the treatment but does not change the way in which the tecar current interacts with biological tissues and the way in which the energy is concentrated, which is a function of the frequency.- Being another impedance positioned between the device and the biological tissues, causes a loss of power/energy which is dissipated from the plate and not released to the relevant biological tissues.
