Capacitive and Resistive Energy Transfer (TECR®) is a treatment that uses the electric capacitor principle to treat many musculoskeletal diseases.
Founded in 1997 in Spain, TECR ® therapy plays an increasingly important role in instrumental physiotherapy.
It is widely used in the treatment of athletes because of its very fast results, improvements can be seen already since the first session.

Compared to other electrical equipment, the main differences are:
- The endogenous type effect (ie the energy used is produced from the inside out)
- High body penetration
- The ability to treat acute diseases
- The fact of having two types of electrodes: the resistive and the capacitive.
How does capacitive and resistive energy transfer work ?
At microscopic level, the cell is like an electric battery, internally to the membrane there is a negative charge, while to its external there is a positive charge.
The potential energy difference must have a fixed value based on the type of fabric. In music, for example, it is -90 mV.
Due to a traumatic or inflammatory event, this difference can be reduced by up to 20/30 mV, causing cell malfunction and preventing recovery.
The TECR® therapy accelerates the cellular regeneration process, thus contributing to a significant reduction in recovery time.
The machine has a stimulating action on the potential of the cell membrane.
The operation of the machine is based on the generation of a high frequency magnetic field; in the market there are machines ranging from 0.45 mhz to 1.2 mhz.
Capacitive and Resistive Energy Transfer® uses the capacitor effect in the human body, induces “displacement” currents in the tissue which are produced by an alternating movement of electrical charges through ions (molecules with a positive or negative charge).
Another effect that the equipment can produce is hyperemia, that is, increased blood flow in the tissues being treated, which is especially useful for unlocking the rigid joints after a long immobilization, contracture or muscle strain :
The application of TECR ® is variable, depending on the joint of the body being treated.
I noticed that the shoulder responds best to the treatment done in athermia (cold), while in the knees I achieved the best results in hyperthermia (very high temperature)
The higher temperature inside the cell increases the metabolism, ie: a greater influx of nutrients and oxygen into the cell and a release of catabolites (residues) to its exterior.
The generated heat is of endogenous origin is the consequence of the resistance of the tissue to the movement of ions (atoms with positive or negative charge) into the cell, caused by the condensing effect of the TECR ®.
The high frequency of the supplied current allows the body tissue to undergo deep heating without causing the muscles to contract, as with electrotherapy ( Tens , Kotz current).
At the vascular level, it acts by balancing the permeability of the capillaries and cell membranes, in addition to stimulating the release of the lymph node stations overloaded by the residues.
When using the resistive electrode, a greater effect is produced on tissues with a lower concentration of water: bones, tendons, adipose tissue and muscular sheath.
The capacitive electrode works on soft tissues with high water content: muscles and blood vessels
Indications of capacitive and resistive energy transfer
TECR ® can be successfully applied to many pathologies, not only in the sports and orthopedic field, but also vascular, rheumatic and aesthetic. I obtained the best results in the treatment of these pathologies:
- Painful shoulder (supraspinatus tendinitis or long biceps head , bursitis , impact syndrome )
- Muscle injuries , muscle pain , tension or spasm
- Ankle sprains with swelling ( swelling ) and inflammation
- Heel spore and plantar fasciitis
- Gonalgia (knee pain) caused by arthrosis , patellofemoral syndrome , sprain,
- Lymphatic drainage of limbs
- Rheumatological pathologies such as ankylosing spondylitis
- Hip arthrosis
- Lumbago or back pain (usually) , neck pain (in the cervical area) and back pain (in the back) caused by inflammation of the tissues.
How do you use capacitive and resistive energy transfer?
There are many models of TECR that vary according to frequency, power, type of materials used, etc.
In practice, it relies on a passive electrode, the “plate”, in contact with the patient’s body, working with a second electrode over the area to be treated.
The electrode can be conducted manually by the physiotherapist or attached to the patient’s affected tissue.
When applying an electric potential difference at two points, a current is formed, so the passive plate is required.
If the second electrode is moved manually, it is necessary to apply a little conductive cream on the area to be treated to facilitate sliding.
According to the pathology, the therapist will decide whether to use the resistive, capacitive circuit or both.
The duration of treatment depends on the condition, being on average about 20 minutes, but can reach up to one hour if it is an acute pathology.
Generally, the patient feels nothing during the session, but in some cases it is necessary to raise the power level to create a thermal effect.
If the physiotherapist considers it appropriate, he can perform certain exercises during the treatment with the TECR or he can massage the affected area by holding the electrode with the palm of the hand.
Contraindications to capacitive and resistive energy transfer
- Malignant neoplasms
- Cardiac pacemaker
- Numbness in the treated area (eg, herniated disc or diabetes may cause loss of foot sensitivity).
How much does Tecar therapy cost?
The price varies according to the hospital or private clinic and the duration of treatment, and may be different in the case of automatic treatment, since it eliminates the cost of the operator / physiotherapist.
Generally part of 50 reais per session, but can reach up to 80/90 reais.
