Whiplash after a collision: physiotherapy in Edmonton
Whiplash-associated disorder after a collision is graded I to III at assessment, and the grade sets the treatment pathway. Our Edmonton physiotherapists favour early gentle movement over rest and collars; most Grade I and II presentations typically improve within 6 to 12 weeks.

What is whiplash after a collision?
Whiplash-associated disorder is graded from I to III at assessment, which determines the treatment pathway. Current evidence supports early gentle movement and reassurance over rest and collars. Most Grade I and II presentations improve substantially within 6 to 12 weeks.
What whiplash actually is
Whiplash-associated disorder describes the neck injury caused by rapid acceleration and deceleration of the head. It does not require a high-speed impact, and vehicle damage is a poor predictor of injury — low-speed collisions produce genuine whiplash routinely.
Symptoms commonly begin 24 to 72 hours after the collision rather than immediately, which is why feeling fine at the scene tells you very little.
The grades, and why they matter
- WAD I — neck pain, stiffness or tenderness, no physical signs on examination
- WAD II — neck symptoms plus musculoskeletal signs such as reduced range or point tenderness
- WAD III — neck symptoms plus neurological signs such as weakness or altered reflexes
- WAD IV — fracture or dislocation, managed medically rather than by physiotherapy first
What treatment looks like
Current evidence favours early, gentle, active movement over rest and immobilisation. Collars are no longer routinely recommended for WAD I and II, and prolonged rest is associated with slower recovery.
Treatment combines reassurance and education with graded range of motion, deep neck flexor work, and manual therapy where it makes movement more comfortable. Most WAD I and II presentations improve substantially over 6 to 12 weeks, though a proportion take longer.
What predicts a slower recovery
High initial pain intensity, early neck stiffness, and — consistently across the research — high levels of fear about movement and low expectation of recovery. The last two are modifiable, which is one reason education is treated as an active ingredient here rather than a nicety.
Questions people ask
How long does whiplash last?
Most WAD I and II presentations improve substantially over 6 to 12 weeks. A proportion take longer, and higher initial pain and fear of movement are both associated with slower recovery.
Can whiplash show up days later?
Yes. Symptoms commonly begin 24 to 72 hours after the collision once the initial adrenaline response settles. This is normal and does not mean the injury is unrelated to the crash.
Should I wear a neck collar for whiplash?
Collars are no longer routinely recommended for WAD I and II. Evidence favours early gentle movement, and prolonged immobilisation is associated with slower recovery.
Does vehicle damage predict how injured I am?
No. Low-speed collisions with minimal visible damage produce genuine whiplash injuries routinely. Damage to the car and injury to the occupant correlate poorly.
Should I wear a neck collar?
Not usually. Soft collars beyond a day or two are linked with slower recovery. Early, gentle movement and staying active are the current standard of care for whiplash-associated disorder, and that is what the plan is built around.
How long does whiplash take to recover?
Most people improve substantially within six to twelve weeks. A smaller group has symptoms for longer, and early treatment, reassurance and activity are the factors most linked with avoiding that. Progress is measured against the first-visit tests.
Can whiplash cause headaches and dizziness?
Yes, both are common. Headache often comes from the upper neck, and dizziness from the neck or from a concussion sustained in the same collision. The assessment screens for concussion as well, because the treatment differs.
