The short version.
- Most low back pain is mechanical, meaning it comes from the muscles, joints, and discs of the back rather than a serious disease, and it tends to improve with movement and a gradual return to activity.
- TECAR delivers a gentle, deep warmth that can relax chronic muscle guarding in the lower back, easing stiffness so that hands-on treatment and exercise feel more comfortable and work better.
- It is a preparation step, not a fix on its own. Active rehabilitation, meaning the exercises and movement that rebuild strength and control, remains the foundation of getting better.
Why movement comes first.
The great majority of back pain is what clinicians call mechanical. It comes from the everyday working parts of the back, the muscles, joints, and discs, rather than from a serious underlying disease. The reassuring part is that this kind of pain usually settles. Staying as active as you reasonably can, moving gently, and returning to normal activity step by step tends to help far more than resting in bed and waiting.
For a new episode, the early focus is usually movement and reassurance rather than any machine. That is why TECAR is rarely the first thing we reach for. It comes into its own later, when an episode has not fully settled and the muscles around the lower back have stayed tight and guarded for a long stretch of time. You can read more about the condition itself on our pages for low back pain and back pain in general.
What TECAR actually does for the lower back.
TECAR uses a radiofrequency current at around 500 kHz to create a comfortable warmth deep inside muscle and other soft tissue, without burning the skin. When the lower back has been sore for a while, the muscles around it often tighten up and stay clenched, which physiotherapists call guarding. That guarding is the body trying to protect a painful area, but over time it can leave the back feeling stiff, tender, and reluctant to move.
The warmth from TECAR can help those guarded muscles relax and loosen. When the area feels less stiff and tender, two things become easier. Hands-on treatment is more comfortable to receive, and the exercises that follow are easier to start and to push a little further. In other words, TECAR clears the way for the active work rather than replacing it. The lasting change still comes from the movement and strengthening you do, not from the warmth itself.
Who it tends to suit.
TECAR for the lower back tends to help a fairly specific group. It is most useful for people whose back trouble has lingered and whose muscles have stayed tight rather than those in the first painful days of a new strain.
- People with chronic muscle guarding, where the muscles around the lower back have stayed tight and protective long after the original problem.
- People with persistent stiffness that makes everyday movement feel restricted and uncomfortable.
- People with stubborn muscle spasm that has not eased with stretching, gentle exercise, or heat packs at home.
For acute back pain, meaning a new and recent flare-up, the usual starting point is different. It is movement, a gradual return to your normal day, and reassurance that most episodes improve. If your pain spreads down a leg, our page on sciatica explains how that is assessed. Whether TECAR fits your situation is something a physiotherapist decides in person, not from a list online. You can read more about good candidates on our page about who should try TECAR.
When to seek urgent care first.
Most back pain is not dangerous, but a small number of warning signs need urgent medical care rather than physiotherapy. If you have any of the following, call 911 or go to the nearest emergency department, which on the North Shore is Lions Gate Hospital in North Vancouver.
- Loss of control over your bladder or bowel, or trouble passing urine.
- Numbness around the saddle area, meaning the inner thighs, the area between the legs, and around the back passage.
- Severe leg weakness, especially if it is getting worse.
- A fever alongside your back pain.
- Back pain that started after a significant trauma, such as a fall or a crash.
These signs are uncommon, but they matter. Do not wait for a physiotherapy appointment if any of them apply to you.
How a back pain plan fits together.
At your first visit, a physiotherapist registered with the College of Physical Therapists of British Columbia takes your history, examines your back, and checks for any of the warning signs above. From there you agree on a plan. That plan is built around active rehabilitation, the exercises and movement that rebuild strength and control in the back and the muscles that support it. This is the part that does the lasting work, and it is the same whether or not TECAR is involved.
If your back is held back by long-standing stiffness and muscle guarding, TECAR may be added as a warm-up step at the start of a session, easing the area so the hands-on treatment and exercises that follow are more comfortable. Other tools may suit you better, such as IMS dry needling for stubborn muscle tightness or massage therapy alongside your rehab. All of it sits inside full physiotherapy care. Medstar Sport Physio and Health is the only clinic in the Metro Vancouver area offering TECAR, and we use it as one tool among many. For general health information you can also read HealthLinkBC.
The practical next step.
If long-standing back stiffness is holding you back, book a physiotherapy assessment. In British Columbia you do not need a doctor's referral to see a physiotherapist, so you can arrange it yourself. At the assessment the physiotherapist examines your back, talks through your goals, and tells you honestly whether TECAR fits your plan. You can book online through our Jane App page or call the clinic on (604) 988-5411. We are at 1325 Marine Drive in North Vancouver.
Common questions.
Can TECAR therapy fix my back pain on its own?+
No. TECAR is a helper that sits inside a physiotherapy plan, not a cure on its own. Most back pain settles with movement, gradual activity, and exercises that build strength and control. TECAR can make that work more comfortable to start by easing tight, guarded muscles, but the active rehab is what does the lasting job.
Is TECAR useful for brand new, acute back pain?+
Usually it is not the first step. New back pain is most often managed with gentle movement, staying as active as you reasonably can, and reassurance that most episodes settle over time. TECAR tends to be more useful later, when muscles around the lower back have stayed tight and guarded for a long time and have not responded to stretching or heat packs.
Does TECAR for back pain hurt?+
Most people feel a comfortable, deep warmth in the area being treated. The physiotherapist keeps the level within what feels pleasant and checks in with you throughout. If anything feels too hot or sharp, they adjust it straight away. It should never be painful.
Do I need a doctor's referral before being assessed?+
No. In British Columbia you can book a physiotherapy assessment directly, without a referral from a doctor. The physiotherapist examines your back, asks about your history, and tells you honestly whether TECAR is a sensible addition to your plan or whether other approaches suit you better.
How many sessions will I need?+
There is no fixed number, and anyone who promises one without examining you is guessing. It depends on how long the problem has been there, what is driving it, and how you respond. Your physiotherapist will set out a plan at your assessment and adjust it as you go, rather than committing you to a block of treatment up front.
