CERVICAL MOTOR DYSFUNCTION AND ITS PREDICTIVE VALUE FOR LONG-TERM RECOVERY IN PATIENTS WITH ACUTE WHIPLASH-ASSOCIATED DISORDERS: A SYSTEMATIC REVIEW

Objective: To study the presence of cervical motor dysfunctions in acute whiplash-associated disorders, evaluate their course and assess their predictive value for long-term recovery. Design: Systematic literature review. Methods: PubMed and Web of Science databases were used to select studies of the presence of cervical motor dysfunctions within the acute stage (<6 weeks) after whiplash trauma and/or their predictive value for the development of chronic whiplash-associated disorders. Results: The presence of cervical motor dysfunctions in the acute stage after whiplash trauma was investigated in 4 cohorts. The course of cervical motor dysfunctions in whiplash-associated disorders was examined in 4 cohorts, and the predictive value on outcome one year post-whiplash trauma was assessed in 3 cohorts. Reduced cervical mobility, disturbed kinaesthesia, and altered muscle activity were found in the acute stage, and these persisted over time in the moderate/severe group. The predictive value of examining the presence of cervical motor dysfunctions was doubtful. The course and predictive value of initial reduced cervical mobility was inconsistent. Conclusion: Cervical motor dysfunctions are present soon after whiplash trauma persisting in those with moderate/severe symptoms. However, these dysfunctions have limited predictive value, and hence may not explain the complex clinical picture of whiplash-associated disorders. This systematic review highlights the need for differentiating between patients with acute whiplash-associated disorders taking into account the biopsychological framework.
