“…This means that physiotherapy plays a vital role in the posture of the chest pattern related to neck pain. 17 This study has limitations on QEC assessments only through questionnaires. The weakness of the questionnaire is whether the respondent understands the content and fills in so seriously that the researcher does not monitor it.…”

“…15 Sitting upright is a good position because it reduces the load on the lumbar and efficiently distributes the contact of the neck muscles. 16, 17 The recline position at an angle of 135° reduces discus pressure by about 25%. 18 The bent position, when the neck or trunk is bent, makes the moment of extension necessary to maintain posture, and the spinal extensor needs to be activated.…”

Background: While working, many educational staffs complain about musculoskeletal problems due to sitting for an extended periods. Sitting posture affects neck pain because the pressure on the intervertebral disc is twice as great when sitting compared to standing. A good sitting posture is to relax momentarily because the muscles experience tension, reducing neck pain. Methods: This cross-sectional study was carried out in December 2022 with a population of Educational Staff at the Universitas Muhammadiyah Surakarta who met the inclusion and exclusion criteria. The sampling technique in this study was purposive sampling, and 84 samples were obtained. The research data were collected by broadcast email, WhatsApp messages, and direct distribution to staff. Data were analyzed with SPSS 25.0 to determine the correlation between sitting posture and the incidence of neck pain. Results: The Spearman Rho test analysis showed a p-value<0.05, indicating a significant relationship between sitting posture and neck pain among educational staffs at the Universitas Muhammadiyah Surakarta. In contrast, the correlation coefficient showed 0.452, indicating a moderate correlation between sitting posture and neck pain. The relationship was in positive value so that the level of neck pain was reduced. Conclusion: The sitting posture is related to neck pain incidence among academic staff at the Universitas Muhammadiyah Surakarta. This study has an excellent impact on observing the factors contributing to neck pain incidence in academic staff at the Universitas Muhammadiyah Surakarta. In contrast, the further study requires finding the other aspects of neck pain in teams to minimize the occurrence of complaints in the future.

This study was to investigate the effect of applying neck flexion during elbow flexion exercise on muscle activity of the biceps brachii, the anterior deltoid and the sternocleidomastoid (SCM). METHODS: Twenty healthy adults participated in this study. The subjects measured %MVIC (Maximal volumetric control) and collected the maximum electromyography (EMG) values in the biceps brachii, anterior deltoid, SCM. The first action was to sit in a sitting position with the eyes facing front and maintained the weight of each section by performing elbow flexion using a tension gauge. The second action was to sit in a sitting position with the head down and maintained the weight of each section by performing elbow flexion using a tension gauge. Paired T-test was used for comparison of the before-and-after neck flexion to analyze the muscle activity of the Biceps brachii of next flexion and

BACKGROUND: Deep neck flexor muscle atrophy and increased superficial neck muscle activation are associated with disability and pain intensity in individuals with neck pain. There is a lack of evidence to support direct assessment of deep neck flexor muscles in a non-invasive way during exercise performance to help determine the effectiveness of different neck strengthening exercises. OBJECTIVE: Compare longus colli (LC) and sternocleidomastoid (SCM) activation between individuals with and without neck pain using real time ultrasound (RTUS) during a series of craniocervical exercises. METHODS: This cross-sectional cohort study recruited 10 control and 10 neck pain participants to complete four deep neck flexor activation activities involving varying levels of craniocervical flexion. Dimensions of the LC and SCM were measured using RTUS at rest and during exercise. Independent t-tests assessed baseline differences and analysis of variance examined activation changes. RESULTS: At rest, the neck pain group had significantly smaller cross-sectional area and thickness of the LC compared to the control group (p< 0.05). During exercise, the neck pain group showed significantly larger increases in LC thickness and cross-sectional area across exercise compared to the control group, with no differences in SCM activation between groups. CONCLUSIONS: Despite atrophy, individuals with neck pain can activate their deep neck flexor muscles appropriately without activating their superficial neck flexor muscles in a supine series of craniocervical flexion exercise as measured by non-invasive ultrasound imaging.
