A Novel Intervention to Promote Engagement in Physical Activity for Individuals With Whiplash Associated Disorder

Plain-language summary

Approximately 50% of adults who have a whiplash injury experience ongoing pain and disability from whiplash associated disorder (WAD). Causes are multifactorial, with considerable variation. Studies evaluating interventions for this population have used group-level design and analysis and, to date, findings have been equivocal and optimal treatment remains a challenge. In addition to pain and disability, patients are frequently insufficiently active for good health, increasing their risk of preventable morbidity and mortality, and compounding the effects of WAD. The proposed study will evaluate an intervention with two novel features. Firstly, the focus is not directly on the reduction of neck pain and disability, but aims to evaluate whether evidence-based health promotion/behavior change strategies can be successfully applied to increase physical activity promotion in this population. The investigator's hypothesis is that the intervention will not only increase participation in health enhancing physical activity, but through that engagement, patients will gain increased confidence to engage in activity in the presence of neck pain, thereby reducing pain-related disability. Secondly, the Single Case Experimental Design enables individual level analysis that is not possible with typical group level designs, including identification of characteristics of responders and non-responders.
