The Effect of Neck-specific Exercise with, or without a Behavioral Approach, on Pain, Disability and Self-efficacy in Chronic Whiplash-associated Disorders

This study’s goal was to compare the effect on self-rated pain, disability and self-efficacy of three interventions for the management of chronic Whiplash Associated Disorders (WAD): physiotherapist-led neck-specific exercise, physiotherapist-led neck-specific exercise with the addition of a behavioral approach, or prescription of physical activity. Two hundred and sixteen volunteers with chronic WAD participated in this randomized, assessor blinded, clinical trial of three exercise interventions. Self-rated pain/pain bothersomeness (Visual Analogue Scale), disability (Neck Disability Index) and self-efficacy (Self-Efficacy Scale) were evaluated at baseline and at three and six months. The proportion of patients reaching substantial reduction in pain bothersomness (at least 50% reduction) was more visible (P<0.01) in the two neck-specific exercise groups (29-48%) compared to the prescription of physical activity group (5%) at three months. At six months 39-44% of the patients in the two neck-specific groups and 28% in the prescription of physical activity group reported substantial decrease in pain. Reduction of disability was also larger in the two neck-specific exercise groups at both three and six months (P<0.02). Self-efficacy was only improved in the neck-specific exercise group without a behavioral approach (P=0.02). However there were no significant differences in any outcomes between the two physiotherapist-led neck-specific exercise groups.

This study showed neck-specific exercise to result in superior outcomes compared to prescription of physical activity in, but the observed benefits of adding a behavioral approach to the implementation of exercise in this study weren't conclusive.

Neck Pain

Out of all 291 conditions studied in the Global Burden of Disease 2010 Study, neck pain ranked 4th highest in terms of disability and 21st in terms of overall burden.
