“…Moreover, an unstable head movement task showed no or small differences in the deep neck muscles EMG activation with increasing di culty to do the task in contrast to the super cial muscle 31 in healthy individuals. These results indicate that the deep muscles support the cervical spine to produce a stable base during movement of the head 29,31 , and that deep neck muscle function may also be possible to detect by noninvasive ultrasound.…”

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.

“…Nonetheless, the greater MFI in the MFSS regardless of age and BMI highlights the complex uniqueness of the multifidus muscle. Indeed, there is evidence that the deep cervical muscles function differently to the superficial muscles during a motor skill task [ 44 ].…”

Muscle size and composition (muscle volume and muscle fat infiltrate [MFI]) may provide insight into possible mechanisms underpinning chronic idiopathic neck pain, a common condition with no definitive underlying pathology. In individuals with chronic idiopathic neck pain > 3 months and age- and sex-matched asymptomatic controls, muscle volumes of levator scapulae, multifidus including semispinalis cervicis (MFSS), semispinalis capitis, splenius capitis including splenius cervicis (SCSC), sternocleidomastoid and longus colli from C3 through T1 were quantified from magnetic resonance imaging. Between-group differences were determined using linear mixed models, accounting for side (left or right), muscle, spinal level, sex, age, and body mass index (BMI). Individuals with pain had greater muscle volume (mean difference 76.8mm3; 95% CI 26.6–127.0; p = .003) and MFI (2.3%; 0.2–4.5; p = .034) of the MFSS compared to matched controls with no differences in relative volume, accounting for factors associated with the outcomes: muscle, spinal level, side (left had smaller volume, relative volume and MFI than right), sex (females had less volume and relative volume than males), age (older age associated with less relative volume and greater MFI), and BMI (higher BMI associated with greater muscle volume and MFI). Greater MFI in individuals with chronic idiopathic neck pain suggests a possible underlying mechanism contributing to neck pain. Perspective: These findings suggest MFI in the MFSS may be radiologic sign, potentially identifying patients with a less favourable prognosis. Future studies are needed to confirm this finding and determine if MFI is a contributor to the development or persistence of neck pain, or consequence of neck pain.
