The short version.
- Whiplash is a neck strain from rapid back-and-forth movement of the head, most often caused by a car crash. Modern care favours early gentle movement, reassurance, and active rehabilitation over prolonged rest or soft collars.
- TECAR delivers a gentle, deep warmth that can relax persistent muscle guarding in the neck, easing stiffness so that hands-on treatment and exercise feel more comfortable.
- It is a supporting step, not a fix on its own. Whiplash after a car crash is covered by ICBC under Enhanced Care, so you can usually start physiotherapy without waiting.
What whiplash actually is.
Whiplash is a strain of the neck caused by a rapid back-and-forth movement of the head, like the crack of a whip. It happens most often in a car crash, where the head is thrown forward and back faster than the neck can comfortably control. The result is sore, stiff muscles and ligaments, often with a headache and a neck that does not want to turn as far as usual. Clinicians sometimes call this a whiplash-associated disorder.
The reassuring part is that most whiplash settles over time. You can read more about the injury itself on our pages for whiplash and neck pain, and about the related headaches that can come with it.
Why gentle movement comes first.
For a long time the standard advice was to rest the neck and wear a soft collar. Current guidelines point the other way. For most neck strains, including whiplash, early gentle movement, reassurance, and a gradual return to normal activity work better than keeping the neck still. A neck that is held rigid for weeks tends to stiffen and recover more slowly, so the goal early on is to keep it moving within comfortable limits rather than to immobilise it.
That is why a machine is rarely the first step. The early focus is showing you safe, gentle movements and reassuring you that most episodes improve. Active rehabilitation, meaning the exercises that gradually rebuild the neck's strength, control, and range of movement, is what drives the recovery. TECAR comes into the picture later, as a way to make that active work more comfortable when stiffness is in the way.
What TECAR actually does for the neck.
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. After a neck injury, the muscles around the neck and shoulders often tighten and stay clenched, which physiotherapists call guarding. That guarding is the body trying to protect a sore area, but when it lingers it can leave the neck feeling stiff, tender, and reluctant to turn.
The deep warmth from TECAR can help those guarded muscles relax. When the area feels less stiff and tender, 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. This is why TECAR is best thought of as an adjunct, a supporting tool inside a plan, rather than a primary treatment for whiplash.
Who it tends to suit.
TECAR for the neck tends to help a fairly specific group. It is most useful for people whose neck trouble has lingered and whose muscles have stayed tight, rather than those in the first days after an injury.
- People with chronic muscle guarding, where the neck and shoulder muscles have stayed tight and protective long after the original injury.
- People with persistent neck stiffness that makes turning and everyday movement feel restricted and uncomfortable.
- People whose stubborn tightness has not eased with gentle movement, stretching, or heat packs at home.
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 neck pain after a strain 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.
- Severe neck pain straight after a major trauma, such as a serious crash or a fall.
- Tenderness over the bones in the middle of the back of the neck, what clinicians call midline neck tenderness.
- Numbness, tingling, or weakness in the arms or legs.
- Problems with balance or walking.
- A severe headache, or a headache that keeps getting worse.
- Any loss of control over your bladder or bowel.
These signs are uncommon, but they matter. Do not wait for a physiotherapy appointment if any of them apply to you.
How a neck and whiplash plan fits together.
At your first visit, a physiotherapist registered with the College of Physical Therapists of British Columbia takes your history, examines your neck, and checks for any of the warning signs above. From there you agree on a plan. That plan is built around gentle early movement and active rehabilitation, the exercises that gradually rebuild the neck's strength, control, and range. This is the part that does the lasting work, and it is the same whether or not TECAR is involved.
If your neck is held back by lingering 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. 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.
If your whiplash came from a car crash, the treatment is covered by ICBC under its Enhanced Care system, and you can usually start without waiting for the claim to be settled. Our page on whiplash recovery under ICBC explains how the coverage works and what to expect.
The practical next step.
If neck stiffness or whiplash 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 neck, 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.
Will TECAR therapy cure my whiplash?+
No. Whiplash recovery is driven by gentle movement and active rehabilitation, meaning the exercises that gradually restore the neck's strength and range. TECAR is a helper that can ease tight, guarded muscles so that hands-on treatment and those exercises feel more comfortable. It is one part of the plan, never the whole plan.
Should I rest my neck and wear a soft collar after a crash?+
Current guidelines point the other way. For most neck strains after a crash, gentle early movement, reassurance, and a steady return to normal activity work better than prolonged rest or a soft collar. Keeping the neck still for long stretches tends to leave it stiffer and slower to recover. Your physiotherapist will show you safe movements to start with.
When in my recovery would TECAR be used?+
Usually later rather than in the first days. The early focus is gentle movement and settling the area. TECAR tends to be more useful when the neck muscles have stayed tight and guarded for a longer stretch and have not loosened with movement and heat alone. Whether it suits you is something a physiotherapist decides after examining your neck.
Is whiplash from a car crash covered by ICBC?+
Yes. Treatment for whiplash after a car crash in British Columbia is covered by ICBC under its Enhanced Care system, which includes physiotherapy. You generally do not need to wait for the claim to be settled before starting care. Our team can explain how the coverage works and help you get started.
Do I need a doctor's referral to be assessed?+
No. In British Columbia you can book a physiotherapy assessment directly, without a referral from a doctor. The physiotherapist examines your neck, asks about how the injury happened, checks for any warning signs, and tells you honestly whether TECAR is a sensible addition to your plan.
