The short answer
TECAR therapy uses radiofrequency electrical energy in capacitive and resistive modes. Heat sensation, device power and clinical outcome are separate considerations.
Radiofrequency as a treatment principle
A TECAR system applies radiofrequency energy through an applicator. Diathermy refers to heat production in tissue. The operator selects the application and dose for the body area using the device instructions.
If this passive treatment is added to rehabilitation, ask why it is relevant to your activities and which measurable goal it supports.
What do CAP and RES mean?
CAP stands for capacitive and RES for resistive. These modes apply electrical energy differently through the electrode construction and current path. They do not, by themselves, prove that a mode selectively heals a particular tendon.
Electrode position, contact and the instructions for use are part of the actual application. Ask the clinician to explain the choice in relation to the treatment goal.
Tecnosix CR5 and TCR150
Sixtus Italia specifies Tecnosix CR5 at 470 kHz, with capacitive and resistive functions and a 7-inch display. Tecnosix TCR150 offers several operating modes; the bipolar applicator is optional.
For a practice, compare handpieces, ergonomics, cleaning and user instruction. Distinguish included parts from optional accessories in the quotation.
Assess evidence for the intended use
Randomised research on capacitive-resistive electric transfer includes knee osteoarthritis. A study concerns a specific patient group and protocol; its findings cannot automatically be applied to every TECAR system, injury or athlete.
Ask which research is relevant to the diagnosis. Frequency control, power and display features describe equipment, not proof of benefit for an individual patient.
Sensation and lasting function
Separate what a person feels during treatment from functional change afterwards and during everyday activity. A device alone does not make a clinician a complete practitioner. Assessment, communication, professional competence, safe application and evaluation all matter.
The patient guide helps you discuss the full plan.
Screening and user instruction
Discuss electronic implants, altered sensation, skin problems and relevant conditions before treatment. Heat sensation is not a simple substitute for dose selection. Follow the specific device instructions and professional assessment.
For a practice, establish who has been instructed, how use is recorded and how accessories are checked. Use the equipment selection checklist.
Frequently asked questions
Is TECAR the same as ultrasound therapy?
No. TECAR uses radiofrequency electrical energy; ultrasound uses mechanical sound waves.
What do CAP and RES stand for?
CAP means capacitive and RES means resistive. They describe different application modes.
Does more warmth mean a better result?
No. Heat sensation is not proof of an appropriate dose or a better clinical outcome.
What frequency does Tecnosix CR5 use?
Sixtus Italia lists 470 kHz. Check the current configuration and documentation before purchase or use.
Is a bipolar applicator included as standard?
The TCR150 bipolar applicator is optional. Inclusion depends on the model and quotation.
How should I compare two TECAR systems?
Compare workflow, accessories, instruction, documentation, maintenance and evidence for the intended indications.
