MicroRNA 320a Predicts Chronic Axial and Widespread Pain Development Following Motor Vehicle Collision in a Stress-Dependent Manner.
Study Design Prospective human cohort study combined with molecular studies. Background A microRNA is a small, noncoding RNA molecule that can play a role in disease onset. Recent studies found that circulating levels of microRNA 320a (miR-320a) are associated with musculoskeletal pain conditions and that miR-320a is stress responsive. ⋯ In cell culture, miR-320a bound stress and pain-associated 3'UTR transcripts (FKBP5, ADCYAP1, PER2, and NR3C1). Conclusion These data suggest that miR-320a may help mediate regional and widespread changes in pain sensitivity after MVC. J Orthop Sports Phys Ther 2016;46(10):911-919. doi:10.2519/jospt.2016.6944.

Are People With Whiplash-Associated Neck Pain Different From People With Nonspecific Neck Pain?
Study Design Secondary analysis of a prospective cohort study with cross-sectional and longitudinal analyses. Background The clinical importance of a history of whiplash-associated disorder (WAD) in people with neck pain remains uncertain. Objective To compare people with WAD to people with nonspecific neck pain, in terms of their baseline characteristics and pain and disability outcomes over 1 year. ⋯ Level of Evidence Prognosis, level 2. J Orthop Sports Phys Ther 2016;46(10):894-901. Epub 3 Sep 2016. doi:10.2519/jospt.2016.6588.

Morphology of Cervical Spine Meniscoids in Individuals With Chronic Whiplash-Associated Disorder: A Case-Control Study.
Study Design Case-control study. Background Cervical spine meniscoids are thought to contribute to neck pain and hypomobility in individuals with chronic whiplash-associated disorder (WAD); however, their morphology has not been studied in a clinical population. Objectives To investigate cervical spine meniscoid morphology in individuals with chronic WAD. ⋯ This may have pathoanatomical implications in chronic WAD. J Orthop Sports Phys Ther 2016;46(10):902-910. Epub 3 Sep 2016. doi:10.2519/jospt.2016.6702.

There have been many advances in the management of neck pain disorders, but a personal frustration as a clinician and researcher in the field is that the incidence of full recovery following a whiplash injury as a result of a motor vehicle crash has not increased and, subsequently, the rate of transition to chronic neck pain has not lessened. The commentaries in this special issue reflect the multifaceted nature of whiplash-associated disorders and the wide-ranging research in the field. ⋯ This should give great confidence and some hope to individuals with whiplash-associated disorders who have long-term pain and functional disability that after the next decade of research and clinical development, the outcomes following whiplash are likely to be vastly improved.

An Investigation of Fat Infiltration of the Multifidus Muscle in Patients With Severe Neck Symptoms Associated With Chronic Whiplash-Associated Disorder.
Study Design Cross-sectional study. Background Findings of fat infiltration in cervical spine multifidus, as a sign of degenerative morphometric changes due to whiplash injury, need to be verified. Objectives To develop a method using water/fat magnetic resonance imaging (MRI) to investigate fat infiltration and cross-sectional area of multifidus muscle in individuals with whiplash-associated disorders (WADs) compared to healthy controls. ⋯ The results of the study also indicate a risk when segmenting single cross-sectional slices, as both cross-sectional area and fat infiltration differ between cervical levels.
