“…Alterations in body posture such as abnormal cervical spine position (for example lack of cervical lordosis) lead to hyperactivity of deep cervical flexors which are related to not only deformities in neck but also in shoulder girdle, head (protraction of head), kyphosis [20][21][22]. We found that the deviation of head position affected almost all children and in the setting of shoulder girdle over it affected 70% of children.…”

“…We found that the deviation of head position affected almost all children and in the setting of shoulder girdle over it affected 70% of children. It should be noted that in the future such a posture as the forward-head and roundedshoulder posture may play a role in the development of shoulder pain and pathologic conditions [21,22]. For this reason, improving children's body posture should be a prophylactic aim of school teachers [21,22].…”

Introduction: The control of body posture is based on the integration of polisensoric stimuli and conscious body image. Previous studies on the influence of vestibular functioning on postural disturbances have been inconclusive. The purpose of this paper was to investigate the effect of vestibular input on the body posture. Material and methods: We examined 65 healthy children (40 girls, 25 boys) at school age 7-12 years. Children were assessed using Kasperczyk Visual-point Method and Southern California Postrotary Nystagmus Test. Statistical analysis was carried out using Statistica software. Mann-Whitney U test and Spearman test were used to determine dependency between quantitative and qualitative characteristics. A p<0.05 was considered statistically significant. Results: The greatest number of postural deviations was observed in the setting of the head (100%) and shoulders (72%). The median Southern California Postrotary Nystagmus Test score corresponded to the published standards. There was a significant association between lumbar hyperlordosis and the results of postrotatory nystagmus following rotation to the right (p=0.033). Conclusions: The fact that there was a significant association between an increased lumbar lordosis and postrotary nystagmus might indicate that the assessment and treatment of postural abnormalities should consider vestibular system examination. This study confirmed that a slight imbalance in the activity of vestibular might lead to postural disturbances.

“…The neck pain group that had been treated by both the ROM technique (joint mobilization) and the physical therapy technique, displayed better results, thereby demonstrating that flexion, extension, left lateral bending, right lateral bending, left rotation, and right rotation were all improved in comparison to the other neck pain group, which had only been treated using the physical therapy technique 19 ) . A study, in which the head-neck flexion exercise was performed using sling equipment, reported that the ROM for flexion and extension was significantly improved 20 ) .…”

[Purpose] The purpose of this study was to assess how stretching exercise training and sling exercise training for stabilization influences the cervical spine angles and cervical range of motion of straight neck patients. [Subjects and Methods] Twenty straight neck patients were selected as subjects and they were randomly divided into two groups, the stretching and sling stabilization exercise groups which 60 minutes of exercise three times a week for 6weeks. All the subjects in each of the two respective study groups received an X-ray and had their cervical range of motion measured, both before and after the exercise. [Results] When differences in the cervical spine angle between the pre- and the post-test were checked, it was found that only the stretching exercise group showed statistically significant decreases in the craniovertebral angle and the cranial rotation angle. When differences in the range of motion between pre- and post-test were checked, the sling stabilization exercise group showed a significant change in flexion, right rotation, left lateral bending, right lateral bending, and the stretching exercise group showed a significant change in left rotation, left lateral bending, and right lateral bending. [Conclusion] These results indicate that both types of exercises are effective at improving the cervical range of motion of straight neck patients, and that the stretching exercise was more effective than the sling stabilization exercise at improving cervical spine angles.

Background and Objectives: Awareness of temporomandibular joint disorder (TMD) is fairly concerning in management of physiotherapy as patients often seek for treatment from orthodontics when pain become their main concerns. In this case, cervical aspects are often overlooked in the treatment of temporomandibular joint disorder. This study aims to determine the effect of cervical extensor strengthening on severity of temporomandibular joint disorder. Methods: A randomized controlled trial study was carried out for 4 weeks to determine the effect of cervical extensor strengthening on severity of temporomandibular joint disorder among university students. A total of 40 participants were recruited via convenient sampling method. Subjects were randomly assigned into two groups: experimental group (E) and control group (C) through lottery randomization. Subjects in experimental group were instructed to perform 1 set of cervical extensor strengthening with 10 repetitions and goldfish exercises whereas subjects in control group were asked to perform goldfish exercises only. A pre-test and post-test severity of TMD, maximal mouth opening and maximal isometric cervical extensor strength were measured for both groups. Results: After 4 weeks of training, there was significant difference in pre-test and post-test severity of TMD and maximal mouth opening for both E and C group. On the other hand, there was significant difference of pre and post-test of maximal isometric cervical extensor strength in experimental group. There was no significant difference in post-test for severity of TMD (p=0.67), maximal mouth opening (p=0.21) and maximal isometric cervical extensor strength (p=0.40) between two groups. Conclusions: The study concluded that, 4 weeks of anti-gravity cervical extensor strengthening exercises protocol showed there was no significantly difference of the severity of TMD and maximal mouth opening between both control and experimental group. On the other hand, goldfish exercises showed significant improvement of maximal mouth opening and reduction in severity of TMD after 4 weeks of intervention period.
