Neck-specific exercise for radiating pain and neurological deficits in chronic whiplash, a 1-year follow-up of a randomised clinical trial.

People with chronic whiplash-associated disorders who develop radiating arm pain and neurological signs often continue to struggle with these symptoms long after the injury, so knowing whether a specific exercise approach helps beyond the early months matters. This study followed up participants from a earlier trial comparing two forms of neck-specific exercise, one with an added behavioural component, against a general physical activity prescription, tracking arm pain, pins-and-needles bothersomeness, and clinical neurological signs over a year. By the one-year mark, those who had done neck-specific exercise, with or without the behavioural approach, reported less arm pain and paraesthesia bothersomeness and had better odds of normal arm strength and nerve tension tests than the physical activity prescription group. The main limitation is that this comes from a single trial, so while the pattern held across several follow-up points, it has not yet been replicated elsewhere.

If you've had whiplash and still deal with pain, numbness, or weakness running down your arm, you may wonder whether a particular kind of rehabilitation could make a lasting difference. This study followed people a year after they took part in a trial comparing two versions of neck-specific exercise programs, one that also included a behavioural (psychologically-informed) component, against a more general advice-based physical activity approach. A year later, those who had done the neck-specific exercise programs reported less arm pain and less bothersome pins-and-needles sensations, and were more likely to have normal arm strength and nerve function on clinical tests, compared with the group given general activity advice.

This suggests the benefits seen soon after treatment may persist over time. That said, this is based on one trial, so while encouraging, it would need to be confirmed by further research before drawing firmer conclusions.

This paper addresses whether the arm pain and neurological benefits seen shortly after neck-specific exercise in chronic whiplash-associated disorders with radiating symptoms persist over a longer timeframe, a question relevant to anyone deciding on rehabilitation approaches and setting recovery expectations for this population. It is a 1-year follow-up of a randomised controlled trial (n=171) comparing neck-specific exercise alone (NSE), neck-specific exercise with a behavioural approach (NSEB), and physical activity prescription (PPA), with assessor blinding and outcomes at 3, 6, and 12 months analysed using linear mixed models and generalised estimating equations. At one year, the NSE and/or NSEB groups showed statistically significant advantages over PPA in self-reported arm pain and paraesthesia bothersomeness, and higher odds of normal key muscle strength and normal upper limb neural tension (all p<0.03).

This informs clinical reasoning by suggesting that structured neck-specific exercise approaches may offer durable benefits over general activity advice for this subgroup with neurological involvement, rather than only short-term gains. The abstract does not report whether NSE and NSEB differed significantly from each other, so the added value of the behavioural component specifically is not established here. It also rests on a single trial, so these findings have not yet been corroborated by independent replication, and the abstract does not report on adverse events.
