“…Trial heterogeneity and small sample size makes it di cult to draw conclusions of neck muscle activation or mechanical function between studies. To our knowledge have only two study evaluated dynamic neck movement with speckle-tracking analyses 25,43 . Bjorklund et al showed highest deformation in contralateral Scap of ve investigated muscles during neck rotation in quadruped standing in individuals without neck pain 43 .…”

“…To our knowledge have only two study evaluated dynamic neck movement with speckle-tracking analyses 25,43 . Bjorklund et al showed highest deformation in contralateral Scap of ve investigated muscles during neck rotation in quadruped standing in individuals without neck pain 43 . An isometric activation of the neck muscles in combination with rotation is needed in this position and the test position and resistance is different form the test in the present study.…”

The deep cervical muscles are very important for stability and initiation of movement of the cervical spine. A whiplash injury can alter neck muscle function, which remains years after the injury and may explain why symptoms such as persistent pain and disability occur. There is currently limited knowledge of dynamic neck muscle function in chronic whiplash-associated disorders (WAD), and to what extent altered muscle function can improve after rehabilitation. Therefore, we used ultrasound to measure deformation and deformation rate in five dorsal neck muscles in participants with chronic WAD versus matched controls in neck rotation. We accomplished real-time, non-invasive ultrasound measurements with speckle tracking, multivariate and mixed design ANOVA analyses. The results showed altered deformation in the three deepest neck muscle layers, with less deformation area in the WAD group compared to controls in rotation to the most painful side at baseline. Participants in the WAD group performed three months of neck-specific exercises, resulting in improved deformation in the deep neck muscles in WAD and to a similar deformation pattern as controls, and the significant group differences ceased. We reveal new and important insight into the capability of ultrasound to diagnose altered neck muscle function and evaluate an exercise intervention.

A whiplash injury can alter neck muscle function, which remains years after the injury and may explain why symptoms such as persistent pain and disability occur. There is currently limited knowledge about dynamic neck muscle function in chronic whiplash-associated disorders (WAD), and about the extent to which altered muscle function can improve after rehabilitation. Ultrasound can detect mechanical neck muscle function by measuring real-time deformation and deformation rate in the muscles. This method was used for five dorsal neck muscles in participants with chronic WAD versus matched controls in resistant neck rotation. We obtained real-time, non-invasive ultrasound measurements using speckle tracking, multivariate analyses, and mixed-design ANOVA analyses. The results showed altered deformation in the three deepest neck muscle layers, with less deformation area in the WAD group compared to controls in rotation to the most painful side at baseline. Participants in the WAD group performed three months of neck-specific exercises, resulting in improved deformation in the deep neck muscles in WAD and with a similar deformation pattern to controls, and the significant group differences ceased. We reveal new and important insights into the capability of ultrasound to diagnose altered neck muscle function and evaluate an exercise intervention.
