Purpose: Changes in the curvature of the vertebral columns of elderly women with increasing age causes various side effects and disorders. Therefore, this study was conducted to evaluate the effectiveness of the 8-figure scapular brace to improve pulmonary function and balance ability based on lung capacity and foot pressure by increasing the vertebral curvature. Methods: Seventeen elderly women with a forward head posture were selected. Women were asked to wear the 8-figure scapular brace and the forced expiratory volume in 1 second (FEV1) and forced vital capacity (FVC) were measured, as were changes in foot pressure. Measurements were conducted three times each and the mean values were used for subsequent analyses. For static evaluation, we used the paired t-test to identify differences between pre and post values. Results: There was no significant difference in FEV1 and FVC before and after use of the brace (p>0.05); however, there was a significant decrease in forefoot pressure and an increase in rearfoot pressure following application of the brace (p<0.05). Conclusion: Application of the 8-figure scapular brace to correct vertebral curvature in elderly women influenced pressure distribution change from immediate effect body arrange of cervical and thoracic. However, wearing the 8-figure scapular brace may interfere with expansion of the chest and therefore respiratory muscle activity. Accordingly, it is necessary to apply appropriate treatment when wearing a scapular brace and to allow a sufficient intervention period while also providing therapeutic interventions such as posture correction or respiration training.

Background: In this paper, the relationship between the Cranio-Vertebral Angle (CVA) and the vital capacity in each position is reviewed, and the vital capacity in the position is studied. Methods: This study targeted 20 non-smoking female students of U university, which is located in Gyeongju-si. To review the Forward Head Posture (FHP) of each subject, CVA was measured, and FVC, FEV1, and FEF (25-75%) were measured and analyzed using a spirometer. Subjects were ordered to exhale three times with ease and then inhale up to their total lung capacity. After then, they were requested to exhale longer than six seconds. Then the inspiration and expiration were repeated. The measurement was executed in three positions, including supine, prone, and sitting. In each position the measurement was repeated twice, and a one-minute break was given between each cycle, so it was measured six times in total. SPSS 14.0 for Windows was used to analyze the data. The subjects' general properties were analyzed using descriptive statistics, and the correlation between the angle and the respiration variable result in each position was analyzed. The result of the respiration variable in each position was analyzed using the one-way ANOVA, and then a Scheffe post-hoc comparison was executed. Results: According to the analysis result of the correlation between the angle and respiration variable in each position, the sitting position and FEF (25-75%) showed a positive correlation (P<0.05). The respiration variable in each position showed a significant difference in FVC (p<0.05), and the Scheffe post-hoc comparison differed in prone and sitting positions. Conclusion: To increase the FVC of FHP patients, different exercises for each position can be applied, and the result of this study can be utilized as background data for further research.

Purpose : The purpose of this study was to investigate the effects of exercise intervention combined with 3D visual feedback and motion observation on postural alignment and cerebral cortical activity in subjects with forward head posture (FHP). Methods : The study included 28 participants with FHP, randomly divided into a 3D visual feedback plus motion observation group (n=14) or control group (n=14). The experimental group received corrective exercise combined with 3D visual feedback and motion observation for FHP, three times a week for four weeks. We examined cervical spine radiographs in the lateral standing position with both arms crossed to measure the craniovertebral angle (CVA) and cervical lordosis (CL). Relative alpha (RA) and beta waves (RB) were measured by wireless dry EEG. Results : The CVA value was significantly different between the groups, and the CL value was significantly different only in the experimental group. RA and RB values were not significantly different before and after intervention in the control group. RB values were significantly decreased before and after intervention in the experimental group. Conclusion : Based on the results of this study, we suggest that interventions combined with motion observation and 3D visual feedback may be effective as exercise methods to improve postural alignment and cerebral activity in subjects with FHP. Further research is required to generalize our results on technical supplementation complemented with 3D visual feedback devices.

PURPOSE: The purpose of this study was to investigate the vital capacity and maximal voluntary ventilationin subjects with forward head posture (FHP). METHODS: Twenty-eight subjects participated in this study (normal 14, FHP 14) and were resident in B city. The mean age, height and weight of subjects was 22.80yrs, 169.36cm and 62.79kg. Subjects were asked to breath maximally for FVC and repeatedly for MVV during 12 seconds. The variables of data were collected as follows: Forced Vital Capacity(FVC), Forced Expiratory Volume in One Second($FEV_1$), $FEV_1$/FVC, Maximal Voluntary Ventilation(MVV). Each trial was performed by 3 times and we used the means to analyze the data. The mann-whitney U test and independent t-test were used to compare the vital capacity between normal and FHP subjects. All statistical analyses were performed using SPSS 21.0 for window versionand p-values less than 0.05 were used to identify significant differences. RESULTS: The FVC, $FEV_1$, $FEV_1$/FVC and MVV of FHP subjects were decreased more than that of normal subjects and the difference was statistically significant between two groups. CONCLUSION: The vital capacity of subjects with FHP was generally lower than normal subjects. This study shows that the vital capacityof subjectswith FHP could be decreased due to the bad neck posture that weakens the respiratory accessory muscles of neck.

Purpose : The purpose of this study was to find out the effect of exercise on the angle and distance between scapular stability and McKenzie stretch exercise. Method : 30 volunteers took part in this experiment and we divided into three groups(experimental group A, experimental group B, control group C). Experimental group A performed scapular stabilization exercise and experimental group B performed McKenzie neck stretching exercise and control group didn't perform any exercise. Experimental group(A, B) received a total of 12 exercise session over a 4 week period (three times per week). Posture and craniovertebral angle changes of the neck using GPS measurements reported. Result : The CVA and distance change after exercise were significantly reduced in the experimental group A and B. Conclusion : Therefore, we have confirmed through experiments reducing a CVA and distance between scapular stabilization and McKenzie neck stretching exercises, whereby we would also be helpful to ensure the treatment of forward head posture.

Purpose : Forward head posture (FHP) is one of the most common postural malalignment of the cranio-cervical region. Previous studies have reported that FHP might affect both temporomandibular joint (TMJ) and cervical muscles, but still remains unclear. The purpose of this study was to compare the changes of craniovertebral angle (CVA) and muscle properties after smartphone use in healthy individuals with and without FHP. Methods : Fifteen healthy individuals aged 18 to 22 years were included. CVA was evaluated using Dartfish motion analysis, and the subjects were divided into two groups according to their CVA: a FHP group (n = 7, CVA less than 48 °) and a control group (n = 8, CVA more than 48 °). MyotonPro was used to measure muscle properties of masseter, digastric and sternocleidomastoid muscles (SCM). Each subject underwent 15-minutes of smartphone task (web browsing or video watching) in relaxed sitting posture. CVA and muscles properties were assessed both before and after the smartphone task. Results : There were significant changes in post measurements of CVA between the groups. Masseter muscle showed significant differences in pre and post measurements of all muscle properties, and digastric muscle showed significance only in muscle tone. Amount of changes (post-pre), however, showed no significant difference in this study. Conclusion : 15-minutes of smartphone task did not affect CVA and muscle properties of masseter, digastric and SCM in both groups, however, there were significant changes in pre and post measurements of CVA and some muscle properties of masseter and digastric muscles. Therefore, CVA, masseter and digastric muscles might be significantly changed in a heavy duration of smartphone usage more than 15-minutes. Further studies are needed regarding duration of smartphone task, assessments in other various TMJ muscle groups, and participants with pathological FHP conditions.

Purpose : This study examined the effects of pain, neck dysfunction, psychosocial level, headache impact test (HIT), postural alignment, and trapezius muscle tone of the complex exercise program using dynamic taping in patients with tension headache and chronic neck pain with forward head posture. Methods : The design of this is a randomized controlled trial (RCT). Thirty-four patients with chronic neck pain were screened using a randomized assignment program and assigned to experimental group (n=17) and control group (n=17). Both groups underwent a complex exercise program. In addition, the experimental group dynamic taping was applied to the upper trapezius muscle. All interventions were applied three times per week for four weeks. The visual analogue scale (VAS), the neck disability index (NDI), short form-12 health survey questionnaire (SF-12), Headache impact test-6 (HIT-6), Craniovertebral angle (CVA), Cranial rotation angle (CRA), upper trapezius muscle tone were compared to evaluate the effect on intervention. Results : Both groups showed significant differences before and after the intervention in VAS, NDI, SF-12, HIT-6, and CVA, CRA (p<.05). In addition, significant differences in NDI and upper trapezius muscle tone were observed between the experimental group and control group (p<.05). Conclusion : A complex exercise program using dynamic taping for patients with tension headache and chronic neck pain with forward head posture are effective method with clinical significance in improving the function and reducing upper trapezius muscle tone.

PURPOSE: This study examined the effects of an exercise program for the thoracic spine and scapula rather than the neck, which is the primary site of pain. METHODS: Thirty-two elementary school teachers with a forward head posture (FHP) were assigned randomly to either the experimental group (n = 16) or the control group (n = 16). The experimental group performed scapular stabilization exercise (SSE) and thoracic extension exercise (TEE), and the control group performed cervical self-myofascial release exercise and stretching exercise. The pulmonary functions, pain, craniovertebral angle (CVA), and cervical range of motion (CROM) were measured before the intervention and six weeks after. RESULTS: The within-group comparisons showed that the VAS and CROM (except for extension) in both groups were significantly different before and after the intervention (p < .05). The changes in the maximum inspiratory pressure (MIP), maximum expiratory pressure (MEP), forced vital capacity (FVC), forced expiratory volume at 1 sec (FEV1), and CVA were significant only in the experimental group (p < .05). The between-group comparisons showed a significant difference in the FVC, FEV1, VAS, CVA, and left lateral flexion (p < .05). CONCLUSION: The combination of SSE and TEE in the experimental group was more effective in improving the FHP and breathing ability. Moreover, the experimental group and control combination appeared to be effective in reducing pain and improving the CROM. The combination of SSE and TEE, which are exercises that do not target the cervical spine directly, was effective in improving the posture, respiration, neck pain, and CROM in elementary school teachers with FHP.
Forward head posture (FHP) is a musculoskeletal disorder that causes neck pain. Several exercise interventions have been used in South Korea to improve craniovertebral angle (CVA) and relieve neck pain. There has been no domestic literature review study over the past 5 years that has investigated trends and effects of exercise intervention methods for CVA with neck pain. This domestic literature review aimed to evaluate the trends and effects of exercise interventions on CVA and neck pain in persons with FHP. A review of domestic literature published in Korean or English language between 2018 and 2022 was performed. Literature search was conducted on Google Scholar and Korea Citation Index by using the following keywords: "exercise," "exercise therapy," "exercise program," "forward head posture," and "neck pain." Ten studies were included in this review. All of the studies showed positive improvements after intervention programs that included exercises. Notably, four of these studies demonstrated significant differences in results between the experimental and control groups. Among the 10 studies, nine measured visual analogue scale or numerical rating scale scores and reported significant reductions in pain following interventions, including exercise programs. Five of these studies showed significant differences in results between the experimental and control groups. Furthermore, six studies that used neck disability index exhibited a significant decrease in symptoms after implementing intervention programs that included exercise, and significant differences in results were found between the experimental and control groups. This domestic literature review provides consistent evidence to support the application of various exercise intervention programs to improve CVA and relieve neck pain from FHP. Further studies are warranted to review the effects of various exercise interventions on FHP reported not only in domestic but also in international literature.
Main cause of low back pain is a poor posture. Most low back pains are due to a poor posture. The poor posture induces muscle tension and finaliy low back pain. The poor posture arehabitually trained from the childhood by the environmetal factors. In general, maintaining good posture during working and sleeping hours are the first line of defence against back pam. (1) Supine posture is the easiest posture that relaxes and fixes muscles. Supine posture is thus a starting position for on exercise. Lying down releases the weight pressures of head and shoulder and thus body can be relaxed and extended which are helpful for treating back pain. However, supine posture can increase the pressure in ribcage posture aspect and disphragram due to visceral oragans. (2) Sitting in one position for a long time results in fatigue and relaxation of spinal muscies. Finally, body strength is weakened and sitting posture will become poor. If this poor posture continues for a longer time, pain will be accompanied due to overelongation of muscle ligaments. The habitual poor posture could induce intervertebral disc distortion. If the intervertebral disc is damaged, sitting in one position or movement causes pain. (3) Abnormal lumbar curve induces the tention of abdominal muscle and paravertebral muscle groups as well as tention of lower limb muscle group connected to pelvis. For a person with weak body strength, muscle relaxation increases curvature in lumbar, chest and cervical regions. This will induce a pelvic anterior tilting of the imaginary line between A. S. I. S. and P. S. I. S. Hip joint extensor muscle acts on releasing the pelvic anterior tilting. Contrections of hamstring muscle and femoral muscle recover the imaginary line between A.S.LS. and P.S.I.S. from pelvic anterior tilting. thus, contraction of rectus abdominis muscle are required to maintain the normal lumbar curve.
