TECAR Therapy: Deep Heat Treatment for Muscle and Joint Pain Explained

Quick answer: TECAR therapy is a physiotherapy treatment that uses a mild radiofrequency current to create deep warmth inside muscles, tendons and joints. It feels like a warm massage and is often combined with hands-on therapy and exercise.

What is TECAR therapy?

TECAR stands for Transfer of Energy CApacitive and Resistive. You may also see it called radiofrequency diathermy or CRet (capacitive resistive electric transfer) therapy.

It is popular in professional sports clubs because it can be used during hands-on treatment and movement, not just while lying still.

How does TECAR therapy work?

The machine sends a low-level radiofrequency current between a handheld electrode and a metal plate placed under your body. As the current passes through, your tissue resists it and warms up from the inside, rather than from the skin surface like a hot pack.

There are two modes:

• Capacitive mode targets soft, water-rich tissue such as muscles and skin.
• Resistive mode targets denser tissue such as tendons, ligaments, joint capsules and the area around bone.

The deep warmth increases blood flow, relaxes muscle tension and may reduce pain signals.

What conditions can TECAR therapy help treat?

It is commonly used for:

• Muscle tightness, strains and post-exercise soreness
• Tendon problems, such as Achilles, patellar (jumper’s knee) and shoulder tendinopathy
• Knee osteoarthritis
• Neck pain and low back pain
• Ankle sprains, after the first 2 to 3 days of injury
• Stiffness after surgery or a period in a cast
• Plantar fasciitis (heel pain)

What happens during a TECAR therapy session?

• You lie down, and a metal return plate is placed under your back or thigh.
• A conductive cream is applied to the treatment area.
• The therapist glides the electrode over the area, often combining it with massage or gentle movement.
• You feel a comfortable, deep warmth.
• A session usually takes 10 to 20 minutes. Most courses involve 5 to 10 sessions, combined with an exercise programme. Tell your therapist straight away if the heat feels too strong or burning.

Who should avoid TECAR therapy?

TECAR should not be used if you have:

• A pacemaker, defibrillator or other implanted electronic device
• Pregnancy
• Cancer in or near the treatment area
• A blood clot (deep vein thrombosis)
• An active infection, fever or open wound in the area
• A fresh injury with bleeding or swelling (first 48 to 72 hours)

Your therapist should take extra care if you have:

• Metal implants in the treatment area
• Reduced skin sensation, for example from diabetes
• Circulation problems
• Epilepsy

Frequently asked questions

Does TECAR therapy hurt?

No. It should feel like gentle, deep warmth. Burning or discomfort means the intensity is too high.

What is the difference between TECAR and a hot pack?

A hot pack warms the skin surface. TECAR generates heat inside deeper tissues, such as tendons and joints.

How many TECAR sessions will I need?

Most people have 5 to 10 sessions, 2 to 3 times a week. You should notice some changes within 3 to 4 sessions.

Can I exercise after TECAR therapy?

Yes. Many therapists use TECAR right before exercise, because warm tissue moves more easily.

Is TECAR therapy safe if I have a knee replacement?

It depends on the device and settings. Tell your therapist about any metal implants before treatment.

Why do sports teams use TECAR?

It can be applied quickly, during massage or movement, and athletes like the feel of it. Its popularity in sport is ahead of the research behind it.
