Abstract:
The Headache Classification Committee of the International Headache Society listed impairments in cervical muscle function as criteria for headaches of cervical spine origin. Fifteen subjects with cervical headache and 15 controls were tested for the frequency of abnormal responses to passive stretching and abnormal muscle contraction. A new test of cranio-cervical flexion was used to assess the contraction of the deep neck flexors. Results indicated a trend towards a higher frequency of abnormal response to passive stretching of the muscles examined in the cervical headache group but only the upper trapezius proved significantly different to the control group. Deep neck flexor muscle contraction was significantly inferior in the cervical headache group. From the perspective of physical characterization of cervical headache, it appears mat response from passive stretch of muscle may not be a strong criterion for cervical headache but deep neck flexor performance may have potential to identify musculoskeletal involvement in headache. The finding may also provide positive directions for conservative treatment of cervical headache.

Abstract:
OBJECTIVEThe mesodermal derangement in Chiari Type I malformation (CMI) has been postulated to encompass the cervical spine. The objectives of this study were to assess the cross-sectional areas (CSAs) of cervical paraspinal muscles (PSMs) in patients with CMI without syringomyelia, compare them with those in non-CMI subjects, and evaluate their correlations with various factors.METHODSIn this retrospective study, the CSAs of cervical PSMs in 25 patients were calculated on T2-weighted axial MR images and computed as ratios with respect to the corresponding vertebral body areas. These values and the cervical taper ratios were then compared with those of age- and sex-matched non-CMI subjects and analyzed with respect to demographic data and clinicoradiological factors.RESULTSCompared with the non-CMI group, the mean CSA values for the rectus capitis minor and all of the subaxial PSMs were lower in the study group, and those of the deep extensors were significantly lower (p = 0.004). The cervical taper ratio was found to be significantly higher in the study cohort (p = 0.0003). A longer duration of symptoms and a steeper cervical taper ratio were independently associated with lower CSA values for the deep extensors (p = 0.04 and p = 0.03, respectively). The presence of neck pain was associated with a lower CSA value for the deep flexors (p = 0.03).CONCLUSIONSPatients with CMI demonstrate alterations in their cervical paraspinal musculature even in the absence of coexistent syringomyelia. Their deep extensor muscles undergo significant atrophic changes that worsen with the duration of their symptoms. This could be related to a significantly steeper cervical taper ratio that their cervical cords are exposed to. Neck pain in these patients is related to atrophy of their deep flexor muscles. A steeper cervical taper ratio and alterations in the PSMs could be additional indicators for surgery in patients with CMI without syringomyelia.

Abstract:
The purpose of this study was to investigate the recruitment pattern of deep and superficial neck flexors evoked by three different cervical flexion exercises using muscle functional MRI. In 19 healthy participants, transverse relaxation time (T2) values were calculated for the longus colli (Lco), longus capitis (Lca), and sternocleidomastoid (SCM) at rest and following three exercises: conventional cervical flexion (CF), craniocervical flexion (CCF), and a combined craniocervical flexion and cervical flexion (CCF-CF). CCF-CF gave the highest T2 increase for all muscles. CCF displayed a significantly higher T2 increase for the Lca compared with the Lco and the SCM. When comparing the CCF and CF, no significant difference was found for the Lca, whereas the Lco and SCM displayed a higher T2 increase during CF compared with CCF. This study shows that muscle functional MRI can be used to characterize the specific activation levels and recruitment patterns of the superficial and deep neck flexors during different cervical flexion exercises. During CCF-CF, all synergists are maximally recruited, which makes this exercise useful for high-load training. CCF may provide a more specific method to assess and retrain Lca muscle performance compared with CF and CCF-CF. This study highlights the need to differentiate between the Lco and Lca when evaluating their function, since these results demonstrate a clear difference in activation of both muscles.

Abstract:
<p>Neck pain is one of most common musculoskeletal condition resulting in significant clinical, social and economic costs. Muscles around cervical spine including deep neck flexors play a key role to support and control its stability, thus monitoring such muscles near cervical vertebrae is important. In this paper, we propose a fully automated computer assisted method to detect cervical vertebrae with K-means pixel clustering from ultrasonography. The method also applies a series of image processing algorithms to remove unnecessary organs and noises in the process. The experiment verifies that our approach is consistent with human medical experts’ decision to locate key measuring point for muscle analysis and successful in detecting cervical vertebrae accurately – successful in 48 out of 50 test cases (96%).</p>

Abstract:
Atlanto-axial rotatory subluxation is a rare, controversial and frequently misdiagnosed condition occurring primarily in children. A single case study design was used to evaluate the effectiveness of cervical stabilisation training and correction of muscle imbalance, following reduction of this condition, in a nine-year-old boy. The study was conducted over a six-week period during which the subject maintained a daily diary to record his symptoms. The programme consisted of various muscle relaxation and lengthening techniques, endurance training of the deep cervical flexors and lower scapular stabilisers, as well as postural re-education. No treatment was directed at the articular component. The patients signs and symptoms were greatly reduced during the study period. This study supports the importance of correcting the muscle dysfunction component in cervicogenic pain sufferers.

Abstract Study aim: To compare the performance of deep cervical flexors (DCF) among computer users (CU) and non-users using the craniocervical flexion test (CCFT). Material and methods: Eighty nine computer users and 100 non-users were recruited for evaluation of their craniocervical muscle performance. The activation score and performance index were assessed using the CCFT. Comparison of craniocervical flexor performance between the two groups was evaluated using the Mann Whitney test. A Chi-Square test was used to test the association between age, years of work and craniocervical flexion. Significance was set at p ≤ 0.05. Results: The median activation score was lower among computer users (median pressure-24 mmHg as compared to non-users (median pressure-28 mmHg) (p < 0.01). The performance index among computer users was lower when compared to non-users. Also, age (p < 0.001) and the years of work experience (p = 0.006) were associated with the DCF performance. Conclusion: CU have lower activation and endurance of the DCF compared to non-users. The endurance of the DCF was associated with the age and years of computer usage.

Objetivo: A finalidade deste estudo foi verificar os efeitos a curto prazo de um protocolo de exercícios isométricos para flexão crânio-cervical no ângulo crânio-vertebral. Metodologia: Vinte indivíduos foram recrutados e distribuídos aleatoriamente entre dois grupos. No grupo experimental (n=10 indivíduos) foi avaliado o ângulo crânio-vertebral 24h antes e após o protocolo. No primeiro dia o protocolo foi realizado na posição ortostática e no segundo dia em decúbito dorsal. A anteriorização da cabeça, expressa através do ângulo crânio-cervical foi avaliada com recurso a videografia e ao programa Kinovea. Resultados: Comparando intergrupos, não foram encontradas diferenças significativas na avaliação no ângulo crânio-vertebral. Já na comparação intragrupos, foi verificada uma diferença significativa no momento após o exercício entre 1º e o 2º dia, no grupo experimental. Conclusão: Os exercícios isométricos com biofeedback não tem um efeito significativo na anteriorização da cabeça nas 24 horas após a aplicação do protocolo quando comparado a um grupo de controlo.
Objective: The purpose of this study was to verify the short-term effects of an isometric exercise protocol for cranium-cervical flexion at the level of the cranium-vertebral angle. Methodology: Twenty individuals were recruited and randomly assigned in to two groups. In the experimental group (n=10 individuals) the cranium-vertebral angle was evaluated 24h later, before and after the protocol. In the first day the protocol was performed in the standing position and on the second day in the supine position. The forward head posture, expressed through the cranium-cervical angle, was evaluated using videography and the Kinovea program. Results: Comparing intergroups, no significant differences were found in the assessment of cranium-vertebral angle. In the intragroup comparison, there was a significant difference at the time after exercise between the 1st and 2nd day, in the experimental group. Conclusion: Isometric biofeedback exercises don’t have a significant effect on head anteriorization within 24 hours of protocol application when compared with a control group.

Abstract:
Purpose: 1, to determine effect of education and exercise on neck pain, disability, cervical posture and muscle function in office workers with sub-clinical neck symptoms; 2, to determine differences in forward head posture in preferred and standardized posture, and 3, to explore the influence of time on work posture in a sub-group of office workers. Subjects: Sixty-six office workers with sub-clinical neck symptoms who utilize computers at least 4 hours per day participated. A sub-group of 27 were videotaped to assess posture over a workday. Methods: Videotaping was performed 15 minutes of the first and last hour of the workday for analysis of the craniovertebral angle. Cervical posture using the CROM was measured on all subjects in standardized and preferred positioning of the trunk and lower extremities. Subjects were randomly assigned to one of three groups: education only (EOG), education and exercise (EEG), or control (CG). Pre and post-test measurements of pain (Visual Analog Scale), disability (NeckDisability Index), forward head posture (FHP), and deep cervical flexor muscle function (Craniocervical Flexion Test and Short Neck Flexor Endurance Test) were assessed for change within group as well as differences between groups over the 8 week period. Results: No difference was found for FHP over 8 hours in the subgroup. FHP was greater in preferred position compared to standardized by 7.59 mm (95% CI 6.27-8.92, p<.001). Median and mean scores improved for all 3 groups on pain and disability with greater improvement in intervention groups. FHP was unchanged/slightly worse in the CG and EOG, and improved in the EEG. Muscle function improved for the EEG. Statistical significance was not found for change scores between groups. Posttest scores were statistically significant for the NDI between EEG (20.45) and the CG (34.47), p=.042, and between the EEG and the EOG (34.59), p=.023 using Kruskall Wallis with adjusted significance for pairwise comparisons. Discussion/Conclusions: Posture over the workday did not change, differences were found based on preferred and standardized positions. Exercise and education intervention for those with sub-clinical neck symptoms show promise but did not demonstrate significance improvement over controls in this study.

Abstract:
ABSTRACT: Whiplash-associated disorders are a common occurrence. Physiotherapy rehabilitation of such disorders include, among others, improving the recruitment ability of the deep cervical flexor muscles. Cervical proprioception, which has recently gained attention, is not commonly addressed. Evidence points to a possible link between cervical proprioception and deep cervical flexor recruitment ability. This study aimed to determine whether such a correlation exists. This is significant as it highlights the role that recruitment training of the deep cervical flexors has on cervical proprioception. A correlation study design was employed that involved 29 patients with whiplashassociated disorders. They were tested in their ability to perform the cranio-cervical flexion test and Revel’s test for proprioception. Linear regression was employed to interpret the results. This study concluded that a correlation exists between the ability to perform the craniocervical- flexion test and cervical proprioception.
