Background: The importance of postural stabilization and cervical mobilization in subjects with pain from the anterior head posture is drawing more attention. However, studies on head and neck stabilizing intervention after mobilization are lacking. Objective: To examine the effects of Kinesiotaping and posture setting exercise on forward head posture (FHP). Design: Crossover Study Design Methods: The subjects were 17 male and female college students in their 20s with FHP. They were randomized into the Kinesiology taping group (KTG) with 9 subjects and posture stabilizing exercise group (PSEG) with 8 subjects. The intervention was conducted for 4 weeks, and changes in pain, craniovertebral angle (CVA), and proprioception were observed before and after intervention. Results: Pain was significantly reduced in the KTG and PSEG both before and after intervention. CVA and proprioception were significantly increased only in the PSEG. The differences in CVA and proprioception between the two groups were significant. Conclusions: These findings suggest that the application of posture setting exercise could decrease pain, proprioceptive error and increase CVA on FHP.

To examine the changes in pain, the severity of the neck disorder, craniovertebral angle, and muscle activity in young adults with forward head posture. 37 "N" University students in their 20s with forward head posture, including both male and female participants. Measurement of pain, NDI (neck disorder index) craniovertebral angle, and muscle activity were taken before and after the 6 week intervention period. The pain was measured using the visual analog scale. The severity of the neck disorder was measured using the NDI The craniovertebral angle was measured by taking a photo. The muscle activity was measured using surface electromyography. Neck posture correction exercises paired with proprioceptive training is the most effective intervention for reducing pain. Both neck posture correction exercises paired with Kinesio taping or proprioceptive training are effective interventions for addressing neck disability, craniocervical angle, and muscle activity. Neck posture correction exercises paired with Kinesio taping or proprioceptive training are more effective at addressing pain, neck disorder, craniocervical angle, and muscle activity than performing the neck posture correction exercises alone.

PURPOSE: This study examined the effects of the craniovertebral angle, proprioception (joint error test), and the upper trapezius on the muscle tone when comparing cervical stabilization and scapula stabilization exercises and when two exercises were performed together. METHODS: The participants in this study agreed in advance, and this study was carried out by recruiting 27 university students in their twenties with mild frontal posture. The subjects were assigned randomly to three groups that performed cervical stabilization exercises, scapular stabilization exercises, and both cervical and scapular stabilization exercises. One-way repeated ANOVA was used to analyze the evaluation values of the 1^st, 3^rd, and 6^th weeks of exercise intervention within the group, and one-way ANOVA was used to compare the difference in the effects of exercise intervention among the three groups. RESULTS: Proprioception was significantly different in the cervical stabilization exercises (CSE) group and the cervical stabilization exercises + Scapular stabilization exercises (CSE+SSE) groups at three weeks, and there was a significant difference between the scapular stabilization exercises (SSE) group and the CSE+SSE group (p < .05). At six weeks, there was a significant difference between the CSE group and the CSE+SSE group, and there was a significant difference between the SSE group and the CSE+SSE group (p < .05). There was a significant difference between three and six weeks in the CSE group (p < .05). In the SSE group, there was a significant difference between pre and six weeks, and between three and six weeks (p < .05). In the CSE+SSE group, there was a significant difference between pre and three weeks, and between pre and six weeks (p < .05). On the other hand, there were no significant differences between CVA and muscular tone in all three groups (P > .05). CONCLUSION: In all groups, the proprioception (joint error test) showed significant improvement, and the CSE+SSE group showed greater improvement than the other groups. As a result, the appropriate combination of neck stabilization exercise and scapular stabilization exercise effectively improved proprioception in the presence of forward head posture (FHP).

Objective: Flexed posture commonly increases with age in older adults and is characterized by kyphosis and forward head posture. Changes in the posture with age affect both balance and mobility. This study was conducted to examine the effects of a cervical stabilization exercise for community-dwelling older adults to improve balance. Design: Two groups pretest-posttest design. Methods: Fifty older adults were randomly assigned into the cervical stabilization exercise group (n=24) and control group (n=25). The cervical stabilization exercise group (n=24) participated in group exercise for 60 minutes twice a week over 4 weeks. Timed up and go test (TUG), four square step test (FSST), functional reach test (FRT), postural sway, cervical range of motion (CROM), proprioception, craniovertebral angle (CVA) were evaluated before and after the intervention. Results: TUG, FSST, FRT, CROM, Proprioception, CVA showed significantly greater improvement, compared with a control group (p<0.05). Conclusions: Findings of this study demonstrate that cervical stabilization exercise can help improve not only neck functional capacities but also balance. Therefore, it may be used as an effective balance exercise program for community-dwelling older adults.

Background: Neck and jaw pain is common and is associated with jaw functional limitations, postural stability, muscular endurance, and proprioception. This study aimed to investigate the effect of jaw and neck pain on cranio-cervico-mandibular functions and postural stability in patients with temporomandibular joint disorders (TMJDs). Methods: Fifty-two patients with TMJDs were included and assessed using Fonseca's Questionnaire and the Helkimo Clinical Dysfunction Index. An isometric strength test was performed for the TMJ depressor and cervical muscles. The TMJ position sense (TMJPS) test and cervical joint position error test (CJPET) were employed for proprioception. Total sway degree was obtained for the assessment of postural stability. Deep neck flexor endurance (DNFE) was assessed using the craniocervical flexion test. The mandibular function impairment questionnaire (MFIQ) was employed to assess mandibular function, and the craniovertebral angle (CVA) was measured for forward head posture. Results: Jaw and neck pain negatively affected CVA (R² = 0.130), TMJPS (R² = 0.286), DNFE (R² = 0.355), TMJ depressor (R² = 0.145), cervical flexor (R² = 0.144), and extensor (R² = 0.148) muscle strength. Jaw and neck pain also positively affected CJPET for flexion (R² = 0.116) and extension (R² = 0.146), as well as total sway degree (R² = 0.128) and MFIQ (R² = 0.230). Conclusions: Patients with painful TMJDs, could have impaired muscle strength and proprioception of the TMJ and cervical region. The jaw and neck pain could also affect postural stability, and the endurance of deep neck flexors as well as mandibular functions in TMJDs.

Purpose : In this study, we compared the effects of ankle, McKenzie, and cervical stabilization exercises in individuals with a forward head posture. Outcome measures investigated included the neck disability index, craniovertebral angle (CVA), cranial rotation angle (CRA), and thickness of the longus colli muscle (LC) and carotid artery (CA) post-intervention. Methods : The study included 20 individuals with a forward head posture, who were assigned to an experimental group (EG, individuals performed ankle exercises) or control group (CG, individuals performed McKenzie and cervical stabilization exercises). The EG intervention was specifically designed to enhance proprioception in the ankle joint and strengthen the ankle muscles to improve overall stability and function. In contrast, CG interventions aimed to improve neck muscle balance and cervical spine alignment. Paired t-tests were used to analyze intragroup changes and independent t-tests to determine intergroup differences pre-and post-intervention. The significance level for all statistical tests was set at α=.05. Results : We observed significant post-intervention improvements in both groups, specifically, in the CVA, CRA, and LC and CA thickness (p<.05). These results indicate that ankle, McKenzie, and cervical stabilization exercises were useful for neck posture correction, improved muscle balance, and enhanced blood flow to the neck. Conclusion : This study underscores the positive effects of ankle, McKenzie, and cervical stabilization exercises in individuals with a forward head posture. Our study highlights the benefits of these exercises for posture correction and overall neck health and the clinical effectiveness and usefulness of ankle exercises as an important intervention to improve forward head posture.

Objective: The popularization of smartphones can lead to abnormal cervical alignment in university students. The aim of this study was to investigate the relationship among smartphone screen time, cervical alignment, and muscle function in university students. Design: Cross-sectional study. Methods: Seventy-five university students participated in the study. They completed the evaluation of cervical alignment and muscle function, such as handgrip strength, proprioception, and muscle quality (tone, stiffness, and relaxation time). All participants recorded their general characteristics and individual smartphone screen time before the evaluation. They were evaluated craniovertebral angle (CVA) using smartphone application (angle meter 360) for measuring cervical alignment. The muscle function was assessed using a digital hand-held dynamometer, dual inclinometer, and MyotonPRO device. Results: Of all participants, twenty-five university students had forward head posture (CVA<49°, 33.33%). Independent t-test revealed that there were significant differences on smartphone screen time, muscle stiffness, and muscle relaxation between the participants with and without forward head posture (p<0.05). There were significant correlations between the smartphone screen time and the CVA, muscle tone, and muscle relaxation (r=-0.493, 0.250, and -0.500, respectively). Conclusions: The results indicate that the university students with forward head posture had high smartphone screen time and muscle stiffness compared to the students without forward head posture, and smartphone screen time might be associated with cervical alignment and muscle quality.
