TECAR Therapy—short for Transfer of Energy Capacitive and Resistive—is an advanced, non-invasive treatment that heats tissue from within to release deep fascial restrictions, boost circulation, calm pain, and speed recovery. Unlike a hot pack or ultrasound, TECAR does not push heat in from the surface; the body generates the therapeutic warmth itself, deep where the problem actually lives. At The Fascia Institute and Treatment Center®, TECAR is delivered by experienced fascial clinicians and guided by Fascial Mapping®—so the energy goes exactly where your tissue needs it.

01 · What Is TECAR Therapy?

TECAR therapy uses radiofrequency energy delivered through two distinct modes: capacitive and resistive. The capacitive mode targets shallower tissues such as skin, superficial fascia, and muscle. The resistive mode reaches deeper—into tendons, ligaments, joint capsules, and other dense, collagen-rich tissue. Being able to move between both layers in a single session is what makes TECAR so versatile across musculoskeletal conditions, offering both precision and range.

A clinical commentary by Lupowitz and colleagues (2025) describes TECAR as a rapidly maturing modality in orthopedic and sports rehabilitation, with growing evidence that it reduces pain, improves range of motion, and supports tissue regeneration.

02 · How Does TECAR Therapy Work?

TECAR therapy passes high-frequency current between an applicator and a return plate, increasing ionic motion inside the tissue. Heat is produced by the tissue itself—not delivered to it—and that controlled internal warmth triggers a cascade of natural healing responses that can continue for hours after the session ends. A foundational physiologic study by Kumaran and Watson (2015) documented exactly how this endogenous heat builds, retains, and decays in living tissue—the science that anchors the modality.

One key effect is vasodilation—the widening of blood vessels. This improves blood flow, delivering oxygen and nutrients to injured or painful areas while clearing waste and reducing swelling. A pilot study by Clijsen and colleagues (2020) confirmed that TECAR measurably increases skin and intramuscular microcirculation, with the deepest changes seen in resistive mode.

TECAR also has an analgesic effect. The combined warmth, circulation, and fascial release downregulate pain signaling in the treated area, and many patients describe a noticeable drop in pain within the first session.

Finally, TECAR promotes tissue regeneration. By energizing cell membranes and warming collagen-rich tissue, it makes restricted fascia and scar tissue temporarily more pliable—the window during which manual release work can reach what was previously inaccessible. It also reduces muscle tightness and encourages lymphatic drainage, clearing inflammation and preventing fluid buildup.

In shortFour mechanisms, one device: endogenous deep heat, improved microcirculation, pain modulation, and enhanced fascial pliability—each working together to relieve pain and speed healing from both recent injuries and long-standing conditions.

03 · What the Research Shows

The TECAR literature has grown substantially over the past decade—particularly in sports medicine, chronic pain, and post-injury recovery. A systematic review by Beltrame and colleagues (2020) in the International Journal of Rehabilitation Research found that nearly all reviewed studies reported improved strength and function and reduced pain after treatment, most commonly in spine disorders and knee osteoarthritis.

In a randomized controlled trial, Kumaran and Watson (2019, Physiotherapy) found that 448 kHz capacitive-resistive radiofrequency significantly improved pain and function in patients with knee osteoarthritis compared with sham treatment and standard care. And in a comparison of operating methods for non-specific chronic low back pain, Barassi and colleagues (2022) demonstrated that both capacitive and resistive modes produced measurable, well-tolerated changes in pain and tissue temperature.

Taken together, the evidence points in a consistent direction: TECAR is safe, well-tolerated, and effective for soft-tissue, joint, and post-injury concerns—especially when it is guided by an accurate diagnosis and layered with hands-on care.

04 · What Conditions Can TECAR Therapy Help?

Research and clinical experience support TECAR across a wide range of orthopedic and sports concerns, including:

  • Tendon and ligament injuries, including chronic tendinopathy
  • Muscle strains and soft-tissue damage
  • Joint pain and stiffness, including knee osteoarthritis
  • Post-surgical and post-procedure recovery, including scar tissue
  • Chronic low back, neck, and postural tension patterns
  • Deep fascial adhesions and restrictions that surface modalities can’t reach

Because it delivers deep effects without mechanical load, TECAR is also well-suited to patients with connective-tissue conditions such as Ehlers-Danlos Syndrome and generalized hypermobility, where joint stress must be minimized. Many patients report faster healing, less pain, and better movement after a series—and athletes use it to recover from hard training and reduce injury risk.

05 · Where TECAR Fits in Your Plan of Care

A TECAR device in untrained hands is just a warm wand. In the hands of clinicians who can map the fascial chain driving your symptoms, it becomes a precision tool. That is why every TECAR course at FIT begins with Fascial Mapping®—the diagnostic backbone that locates the restriction so the energy can release it. We also layer TECAR with the rest of our practice when a case calls for it:

06 · Is TECAR Therapy Right for You?

TECAR may be a strong fit if you:

  • Have chronic muscle or joint pain
  • Are recovering from an injury or surgery and want to heal faster
  • Feel limited by pain or stiffness
  • Want a non-invasive alternative to injections or surgery
  • Are looking for preventive care to support an active lifestyle

TECAR has an excellent safety record, but it isn’t right for everyone—certain implants, pregnancy in the treatment field, active malignancy, acute clots, and open wounds are among the situations we screen for. Every patient is evaluated first, and energy, mode, and dwell time are tailored to your tissue.
