- ObjectiveThe purpose of this study was to compare the mechanical activity of the neck muscles during loaded arm lifting tasks in individuals with long-standing disability after anterior cervical decompression and fusion (ACDF) with that of healthy controls.MethodsTen individuals (mean age, 60 years; SD, 7.1) who underwent ACDF (10-13 years previously) for cervical disc disease and 10 healthy age- and sex-matched controls participated in the study. Ultrasonography was used to investigate the degree of deformation and deformation rate of ventral and dorsal neck muscles at the C4 segmental level during a single (1 × arm flexion to 120°) and repeated (10 × arm flexion to 90°) loaded arm elevation condition.ResultsThe ACDF group showed greater deformation and deformation rate of the longus capitis (P = .02) and deformation rate of the sternocleidomastoid (P = .04) during the 120° arm lift. For repeated 90° arm lift, there was a significant group effect with higher deformation rate values observed in the longus capitis (P = .005-.01) and multifidus (P = .03) muscles in the ACDF group. Muscle behavior did not change the repeated arm lifts (no group × time interactions) for either the ventral or the dorsal muscles.ConclusionsFor study participants, greater muscle mechanical activity levels were observed in the ventral and multifidus muscles of patients with persistent symptoms after ACDF. These differences may indicate altered motor strategy in this patient group when performing the upper limb task and may need to be considered when prescribing exercise for postsurgical rehabilitation.

- Previous studies have shown that postural orientations of the neck, such as flexed or forward head postures, are associated with heightened activity of the dorsal neck muscles. While these studies describe the impact of variations in neck posture alone, there is scant literature regarding the effect of neck posture on muscle activity when combined with upper limb activities such as lifting. The purpose of this study was to evaluate the effect of three different neck postures on the activity of the different layers of the dorsal neck muscles during a lifting task. Ultrasound measurements of dorsal neck muscle deformation were compared over two time points (rest, during lift) during a lifting task performed in three different neck postural conditions (neutral, flexed and forward head posture) in 21 healthy subjects. Data were analysed by post-process speckle tracking analysis. Results demonstrated significantly greater muscle deformation induced by flexed and forward head postures, compared to the neutral posture, for all dorsal neck muscles at rest (p < 0.05). Significant condition by time interactions associated with the lift was observed for four out of the five dorsal muscles (p < 0.02). These findings demonstrate that posture of the cervical spine influenced the level of muscle deformation not only at rest, but also when lifting. The findings of the study suggest that neck posture should be considered during the evaluation or design of lifting activities as it may contribute to excessive demands on dorsal neck muscles with potential detrimental consequences.

- Objective: Guild boards and pulleys are apparatus commonly used to train cervical muscle function for their purported benefit in facilitating activity of the deeper muscle layers, although this effect has not been substantiated. The objective of this study was to compare the activity of the different layers of cervical muscles when performing exercise with these 2 types of apparatus.Subjects: A total of 19 healthy persons (mean age 28 years, (standard deviation 7 years).Design: Ultrasound measurements of muscle deformation and deformation rate were recorded from the dorsal and ventral neck muscle layers during extension and flexion exercises. Pulley exercises were performed in the upright sitting position against a standardized resistance (men 2 kg, women 1 kg) and guild board exercises at an angle of 45 degrees.Results: The dorsal muscles generally showed greater levels of deformation and deformation rate during exercise with the guild board compared with the pulley system (p<0.05), but with no significant differences in relative activity between the deep and superficial muscle layers (condition x muscle interaction (p>0.05)). No differences were observed for the ventral muscles between exercise methods (p>0.05).Conclusion: While both exercise methods appear to train cervical muscle function, neither appear to be more selective in facilitating deep cervical muscle activity, probably as they involve very similar cervical kinematics.

- Objective: This study aimed to describe and compare the longitudinal mechanical activity, deformation, and deformation rate of the different layers of dorsal and ventral neck muscles in healthy volunteers during head lifts against gravity. Methods: The cross-sectional study included 19 healthy volunteers (mean age, 28 years; SD, 7 years). Ultrasound with speckle-tracking analysis was used to investigate longitudinal mechanical activation, deformation, and deformation rate of dorsal and ventral neck muscles in real time during a head lift. Significance levels were set as P = .025 or P = .0125, depending on the number of comparisons. Results: The dorsal neck muscles did not significantly differ in deformation (P > .04); however, the multifidus had a higher deformation rate than all other dorsal muscles (P < .003). The sternocleidomastoid had significantly higher deformation than the longus capitis (P = .005) and colli (P = .001) but a lower deformation rate than the longus colli (P = .02). Conclusion: The sternocleidomastoid deformed more than the deeper muscles, but it did significantly slower than the longus colli. Among the dorsal muscles, the deepest (the multifidus) had the highest deformation rate.

- Objectives To compare mechanical activity (deformation and deformation rate) of the dorsal neck muscles between individuals with longstanding symptoms after anterior cervical decompression and fusion (ACDF) surgery and healthy controls.Design Preliminary cross-sectional study.Setting Neurosurgery clinic.Participants Ten individuals {mean age 60 [standard deviation (SD) 7.111 who had undergone ACDF surgery 10 to 13 years previously and 10 healthy age- and sex-matched controls.Main outcomes Mechanical activity of the different layers of dorsal neck muscles, measured at the C4 segment using ultrasonography (speckle tracking analysis) during a standardised, resisted cervical extension task.Results A significant group x muscle interaction was found for muscle deformation (P<0.03) but not for deformation rate (P>0.79). The ACDF group showed significantly less deformation of the semispinalis capitis muscle during the extension task compared with the control group [mean 3.12 (SD 2.06) and 6.64 (SD 4.17), respectively; mean difference 3.34 (95% confidence interval 0.54 to 7.21)].Conclusions As the semispinalis capitis muscle is a powerful neck extensor, the finding of altered activation following ACDF surgery lends support to the inclusion of exercise to train neck muscle performance in the management of these patients.

- There is currently a lack of information regarding neck muscle activity during specific exercises. The purpose of the present study was to investigate deformation and deformation rate in different layers of dorsal and ventral neck muscles during isometric neck muscle contraction in individuals after anterior cervical decompression and fusion and in healthy controls. This study included 10 individuals (mean age 60 years; SD 7.1) with a verified, long-standing neck disorder and 10 healthy, age- and sex-matched controls. Ultrasonography and post-process speckle tracking analysis was used to investigate the degree and the rate of neck muscles motions at the C4 segmental level during sub-maximal, isometric resistance of the head in a seated position. None of the analyses performed showed significant differences between groups (p > 0.05). In the dorsal muscles, both groups exhibited a higher deformation rate in the multifidus than in the trapezius, splenius, and semispinalis capitis (p ≤ 0.01). In the neck disorder group, the multifidus also showed a higher deformation rate compared to the semispinalis cervicis (p = 0.02). In the ventral muscles of patients with neck disorders, the longus colli had a higher deformation rate than the sternocleidomastoid (p = 0.02). Among the healthy controls, the multifidus showed a higher degree of deformation (p = 0.02) than the trapezius. In conclusion, our results showed no significant differences between the two groups in mechanical neck muscle activation. Larger studies with different exercises, preferably with a standardized measure of resistance, are needed to investigate whether patients and controls show differences in deformation and deformation rates in neck muscles.

- Previous studies have shown altered neck muscle function in individuals with chronic whiplash associated disorder (WAD). However, we lack real-time investigations with non-invasive methods that can distinguish between the different ventral neck muscle layers. This study investigated deformations and deformation rates in the sternocleidomastoid (SCM), longus capitis (Lcap), and longus colli (Lco) muscles with real-time ultrasonography. Twenty-six individuals with WAD were compared with 26 controls, matched for age and sex. Ultrasound imaging of the SCM, Lcap, and Lco were recorded during 10 repetitive arm elevations. The first and tenth arm elevations were post-process analyzed with speckle tracking. There were few significant differences in the deformations or deformation rates in the SCM, Lcap, and Lco between the WAD and control group. In controls, deformations and deformation rates showed linear positive relationships between SCM/Lcap, SCM/Lco, and Lcap/Lco which increased from the first arm elevation (R-2 = 0.14-0.70); to the tenth arm elevation (R-2 = 0.51-0.71). The WAD group showed similar or weaker linear relationship (R-2 < 0.19) during the tenth compared to the first (R-2 < 0.44) arm elevation except for deformations in Lcap/Lco (R-2 = 0.13-0.57). This result indicated that deformations and deformation rates in one muscle were correlated by similar deformations and deformation rates in other neck muscles in the control group, but this interplay between muscles was not found in the WAD group.

- Objective: To evaluate the capacity of the ultrasound-based method of speckle tracking analysis to detect changes in multilayered dorsal neck muscle activity induced by performing a lifting task. Subjects: Twenty-one healthy individuals. Design: Participants performed a loaded lifting task in 3 different postural orientations of the neck (neutral, flexed and forward head posture). Ultrasound images were recorded and speckle tracking analysis was used to quantify muscle deformation and deformation rate over 3 equal time-periods during the lifting sequence (rest, mid-lift and end-lift). Results: Significant main effects of postural orientation for the deformation measure (p<0.05) and time for the deformation rate measure (p<0.05) were observed in all dorsal muscles examined. Significant time by postural interactions for the deformation measure were observed in the trapezius, semispinalis cervicis and multifidus (p<0.05) and in the semispinalis cervicis (p<0.05) for the deformation rate measure. Conclusion: Speckle tracking analysis ultrasound measurements can detect differences in multilayered muscle activity of the dorsal neck induced by postural variations during a lifting task. Findings for the deformation and the deformation rate measures suggest that they quantify a different, albeit related, mechanical event during muscle contraction in a functional task such as lifting.

- Background: The aims of this study are to 1) determine the scope of musculoskeletal (MSK)-related clinical research in Sweden; 2) collate the amount of first-tier funding received; 3) discuss strategies and infrastructure supporting future MSK clinical trials in Sweden. Methods: A systematic scoping review protocol was applied in PubMed, Scopus, and SweCRIS databases. The articles were examined, and data were extracted in multiple stages by three blinded authors. Results: The search strategy resulted in 3,025 publications from 479 Swedish-affiliated authors. Primary health care was the basis for 14% of the publications, 84% from secondary health care, and 2% from occupational health care with a similar proportional distribution of first-tier research grant financing. Approximately one in six publications were randomized controlled trials (RCTs), while the majority were of observational cohort design. The majority of publications in primary and occupational health care were related to pain disorders (51 and 67%, respectively), especially diagnosis, prognosis, and healthcare organizational-related interventions (34%) and rehabilitation (15%) with similar proportional distribution of first-tier research grant financing. In secondary health care, rheumatic inflammatory disorder-related publications were most prevalent (30%), most frequently concerning diagnosis, prognosis, and healthcare organizational-related interventions (20%), attracting approximately half of all first-tier funding. Publications related to degenerative joint disorders (25%), fractures (16%), and joint, tendon, and muscle injuries (13%) frequently concerned surgical and other orthopedic-related interventions (16, 6, and 8%, respectively). Pain disorder-related publications (10%) as well as bone health and osteoporosis-related publications (4%) most frequently concerned diagnosis, prognosis, and healthcare organizational-related interventions (5 and 3%, respectively). Conclusions: Swedish-affiliated MSK disorder research 2010-2020 was predominantly observational cohort rather than RCT based. There was skewed first-tier funding allocation considering prevalence/incidence and burden of disease. Use of infrastructure supporting register-based RCTs, placebo-controlled RCTs, and hybrid effectiveness-implementation studies on prevention and clinical intervention is important strategies for the future in all healthcare sectors.

- Background: Musculoskeletal disorders (MSK) are a global burden causing significant suffering and economic impact. Systematic identification and targeting of research questions of highest interest for stakeholders can aid in improving MSK disorder knowledge and management.Objective: To obtain Swedish MSK researchers' opinions and views on a collaborative Swedish MSK network (SweMSK) and identify future research areas of importance for Swedish MSK research.Methods: A web-based survey was conducted July to September 2021 to collect data from 354 Swedish MSK researchers. The survey focused on the need, objectives, and structure of a SweMSK network and identified prioritised areas for future MSK research.Results: The study included 141 respondents, of which 82 were associate professors or professors. The majority (68%) supported the creation of a new musculoskeletal network. The most supported element was increased collaboration regarding nationwide and multicenter studies. Respondents recommended the creation of a homepage and the establishment of national work groups with different specific interests as the primary elements of a new network.Conclusion: The results demonstrated a need and desire for increased national research collaboration and the creation of a new musculoskeletal network. The high academic experience and active research participation of the respondents suggest the need for MSK disorder knowledge and management improvement in Sweden. Therefore, the SweMSK network may help facilitate effective collaboration and research efforts that can contribute to the advancement of MSK disorder management and care. This study may provide valuable insights for policymakers, clinicians, and researchers to improve MSK disorder care and management in Sweden.
