The short version.
- TECAR uses a gentle radiofrequency current at around 500 kHz to create deep warmth through a volume of tissue, which relaxes muscle tightness, improves circulation, and makes a region more ready for hands-on work and exercise.
- Class IV laser therapy, also called photobiomodulation or high-power laser therapy, delivers concentrated light energy to a focused point to influence inflammation and cell activity, and is often used for acute injuries and localized pain.
- They feel different and they suit different jobs. A clinician may use them together, and both are add-on tools inside a wider physiotherapy plan rather than stand-alone cures.
What each one does.
TECAR works by passing a high-frequency electric current, at around 500 kHz, between a handpiece on your skin and a flat return plate placed elsewhere on the body. Your own tissue resists that current slightly and warms from the inside. Because the warmth is created within a broad region rather than laid on the surface, it can reach deeper muscle and joint structures. The goal is to ease protective muscle tightness, known as muscle guarding, improve local blood flow, and increase range of motion, so that the manual therapy and exercise that follow can do more.
Class IV laser therapy is different in kind. It uses a beam of concentrated light energy aimed at a focused point on or near the injury. The aim is to influence inflammation and the activity of cells in that small area rather than to heat a large volume of tissue. For this reason it is often chosen for acute injuries, localized inflammatory or painful conditions, and post-surgical sites once your surgeon or therapist has cleared you to begin treatment.
Side-by-side comparison.
| TECAR | Class IV laser | |
|---|---|---|
| Mechanism | Radiofrequency current at around 500 kHz that warms tissue from the inside | Concentrated light energy aimed at a focused point |
| Depth and what it targets | Deep warmth across a broad volume of muscle, tendon, and joint tissue | A smaller, localized area at and near the surface of the injury |
| What it feels like | A comfortable deep warmth over a wide area | A gentle warmth at a focused point |
| Best uses | Muscle guarding, stiffness, and limited range, and preparing tissue for hands-on work and exercise | Acute injuries, localized inflammation or pain, and cleared post-surgical sites |
| Stand-alone vs add-on | An add-on used to open a window for the rest of treatment | An add-on used to support a specific injury site |
How they feel in the room.
The experience of the two treatments is noticeably different, which is one of the clearest ways to tell them apart. With TECAR, the therapist moves a handpiece over a wider region and you feel a steady, comfortable deep warmth spreading through the area. With Class IV laser, the device is held over a single focused point and you feel a gentle warmth right there. Neither should ever feel uncomfortable, and you should tell your therapist straight away if either becomes too hot so they can adjust the settings.
Because they target different things in different ways, they are not really rivals. A clinician will often reach for laser when there is a specific inflamed or healing area to support, and for TECAR when the surrounding muscle is tight and needs to loosen before hands-on work and exercise. In many plans the two are used together over the course of treatment.
Both available in North Vancouver.
Medstar Sport Physio & Health at 1325 Marine Drive in North Vancouver offers both treatments under one roof. We are the only clinic in the Metro Vancouver area offering TECAR, and we also run Class IV laser therapy in-house. That means your therapist can choose either one, or combine them, based on what your assessment shows rather than on what happens to be available.
Both are add-on tools that sit inside a wider physiotherapy plan, not stand-alone cures. If you want to understand how TECAR stacks up against other physical treatments such as shockwave and ultrasound, see our wider comparison page. For laser and post-surgical care, see how we use TECAR for post-surgical recovery. For general, plain-language guidance on physiotherapy and managing pain, HealthLinkBC is a reliable starting point: HealthLinkBC. Neither treatment is a substitute for assessment and advice from a registered physiotherapist.
Common questions.
Is TECAR or laser better for my injury?+
Neither is better in general. They do different jobs. TECAR creates deep warmth across a broad area to relax tight muscle, improve circulation, and free up movement, which suits stiff or guarded muscles and chronic complaints. Class IV laser delivers focused light energy to a smaller spot and is often chosen for acute injuries, localized inflammation, and post-surgical sites once you are cleared to begin. Your physiotherapist matches the tool to the problem after assessing you.
Do TECAR and laser feel different during treatment?+
Yes. TECAR feels like a comfortable deep warmth spread over a wider region as the therapist moves the handpiece. Class IV laser feels like a gentle warmth at a single focused point where the device is held. Both are meant to be comfortable, and you should tell your therapist right away if either feels too hot.
Can I have both TECAR and laser in the same plan?+
Often, yes. A clinician may use laser to address a localized inflamed or healing area and TECAR to warm and loosen the surrounding muscle so hands-on work and exercise go better. They are both add-on tools inside a wider physiotherapy plan rather than treatments you would choose on their own.
Where can I get both TECAR and laser in North Vancouver?+
Medstar Sport Physio & Health at 1325 Marine Drive in North Vancouver offers both in-house. We are the only clinic in the Metro Vancouver area offering TECAR, and we also run Class IV laser therapy, so your therapist can combine them when that fits your case. Call (604) 988-5411 or book online to ask which makes sense for you.
