Trauma-focused cognitive behavioural therapy and exercise for chronic whiplash with comorbid posttraumatic stress disorder: a randomised controlled trial.

People with long-lasting whiplash-related neck problems often also carry symptoms of post-traumatic stress, yet usual rehabilitation tends to focus on exercise alone. This trial asked whether adding therapy aimed specifically at trauma symptoms, alongside exercise, would ease neck disability more than supportive, non-trauma-focused therapy paired with the same exercise program. Both groups received ten weeks of psychological therapy followed by six weeks of exercise, with outcomes tracked over a year. The two approaches produced similar results for the main measure, neck pain-related disability, at every time point measured.

Most other outcomes were also similar, with one exception: trauma-focused therapy showed an advantage for post-traumatic stress symptoms specifically at sixteen weeks. Both groups did improve in neck disability over time, though both remained moderately disabled, and because there was no comparison without any psychological therapy, it is not clear how much of that improvement reflects the specific treatments versus other factors like therapeutic attention or the shared exercise component.

If you live with whiplash symptoms that have lasted months or years and also notice signs of trauma-related stress, you may wonder whether therapy addressing that trauma directly, on top of exercise, would help your neck pain more than other forms of psychological support plus exercise. This study compared exactly that, following over a hundred people for a year. The results showed no difference between the two approaches when it came to neck-related disability, the main thing being measured.

Both groups did show improvement in their neck symptoms over time, starting around four months in, though people in both groups still had moderate ongoing disability by the end. One difference did appear: those who received trauma-focused therapy showed more improvement in post-traumatic stress symptoms at the four month mark specifically, though this was just one result among many measured and could reflect chance rather than a true difference.

This was one trial, and it does not tell us why both groups improved similarly, since there was no group receiving exercise alone for comparison.

This trial addresses whether tailoring psychological treatment to trauma symptoms, rather than offering general supportive therapy, improves outcomes for patients with chronic whiplash-associated disorder who also present with post-traumatic stress. Both arms received ten weeks of psychological intervention plus six weeks of exercise, mirroring the kind of combined care increasingly discussed for this comorbid presentation. The primary outcome, neck pain-related disability on the 0-100 Neck Disability Index, showed no statistically significant difference between trauma-focused cognitive behavioural therapy and supportive therapy at 16 weeks, 6 months, or 12 months (treatment effects ranging from 0.59 to 1.85, with confidence intervals crossing zero throughout).

Most secondary outcomes followed the same pattern, with one exception: trauma-focused therapy showed improvement in post-traumatic stress symptoms at 16 weeks, though this is a single favourable result among many comparisons and could represent a chance finding rather than a genuine treatment advantage. Both groups reached clinically important improvement in disability from 16 weeks, though both remained moderately disabled, and the trial design cannot isolate whether this improvement stemmed from either specific psychological approach, the shared exercise component, or non-specific therapeutic contact, since there was no no-treatment comparator.
