The best trial on exercise for chronic whiplash found that a 20-session physiotherapy exercise program reduced pain no more than a single session of advice with telephone support. That result is uncomfortable for anyone who builds care plans around exercise, including me, and it deserves a straight reading. Patients in Charlotte should know what it shows and what it does not.
The PROMISE Trial
An Australian trial randomized 172 people with chronic whiplash, between three months and five years after injury, with grade 1 or 2 symptoms (Michaleff, Lancet 2014). One group received a comprehensive exercise program of 20 sessions. The other received one advice session plus telephone support. Pain was measured on a 0 to 10 scale by an assessor who did not know the group assignment.
The difference in pain between groups was 0.0 at 14 weeks, 0.2 at 6 months, and minus 0.1 at 12 months. None was significant. Signs of nervous system sensitization and posttraumatic stress symptoms did not change the result. No serious adverse events were recorded.
The trial was funded in part by the National Health and Medical Research Council of Australia and by motor accident insurance authorities in New South Wales and Queensland.
What It Does Not Show
The trial tested chronic whiplash, not acute injury. It tested grade 1 and 2, not patients with neurologic signs. It compared exercise with advice, not exercise with nothing. And the advice group received active guidance, not neglect. The trial does not show exercise is useless. It shows that, for chronic grade 1 and 2 whiplash, a long supervised program did not add pain relief beyond good advice.
Timing and Who Recovers
In a meta-analysis of 38 cohorts, most whiplash recovery happened in the first three months and then leveled off (Kamper, Pain 2008). The patients least likely to recover are identifiable early: high baseline pain, headache at the start, high disability scores, and catastrophizing were among the significant predictors in a 2013 meta-analysis (Walton, J Orthop Sports Phys Ther 2013).
How I Use This
Advice is treatment, and it is the part of care that the trial supports most directly. Every patient gets a clear explanation of the findings, what the imaging excluded, and what activity is safe. Exercise is part of care when it targets a specific deficit found on exam, and the plan is reassessed when it is not producing measurable change. For a patient with a documented ligament injury, exercise focused on motor control has a mechanistic rationale, but I tell patients that the controlled trial evidence for it in chronic whiplash is not strong.
For an example of how post-collision imaging findings and outcomes are documented in the peer-reviewed literature, read Dr. Justin Dick's published case report on refractory lumbar pain following a motor vehicle accident in a geriatric patient.
Frequently Asked Questions
Does exercise help chronic whiplash?
In a randomized trial of 172 patients, a 20-session exercise program reduced pain no more than advice with telephone support at 14 weeks, 6 months, or 12 months (Michaleff, Lancet 2014).
Is advice alone enough for whiplash?
For chronic grade 1 and 2 whiplash, simple advice was as effective as a comprehensive exercise program for pain in the PROMISE trial.
Does the PROMISE trial apply to acute whiplash?
No. It enrolled people three months to five years after injury with grade 1 or 2 symptoms.
When does most whiplash recovery happen?
In the first three months, after which recovery tends to level off (Kamper, Pain 2008).
