“…As the head moves forward, the inhalation muscles such as sternocleidomastoid, scalenus, suboccipitalis are shortened, limiting the expansion of the rib cage This restriction of rib mobility reduces the amount of air that enters the lungs [6,8,9]. Another study analyzed the relationship between the craniovertebral angle and respiratory circulatory function, and showed that the smaller the craniovertebral angle, the less carbon dioxide emission.…”

“…The value of FVC may depend on the movement of the diaphragm and the extent of thoracic cage expansion. 12 Also, in order to achieve this forced expiration, the volume in the thoracic cavity must be reduced rapidly, and transversus abdominis, external oblique abdominal, internal oblique abdominal and rectus abdominis muscle must be actively contracted. 23 For the women in their twenties, we can consider that contraction of transverse abdominis by the application of Figure-8 brace caused elevation of diaphragm to the thoracic cavity by the increase of abdominal pressure, and facilitated exhalation of breath.…”

Purpose: To improve pulmonary function and decrease in balance ability with increasing forward head position and vertebral curvature, we applied Figure-8 brace to confirm the immediate effect on vital capacity and balance and to see if it is applicable. Methods: A total of 34 elderly women aged 65 or older and young women in their 20s with FHP were screened to measure vital capacity, measuring the forced expiratory volume in 1 second (FEV1) and forced vital capacity (FVC), and measuring the foot pressure to see the change in balance. For statistical analysis, the difference between pre and post values was compared using pared t-test. Results: As a result of vital capacity measurements, there was no significant difference between FEV1 and FVC for women over 65 years old (p> 0.05). Young women in their 20s had no significant difference in FEV1 (p> 0.05), and FVC had significant differences (p< 0.05). In measuring foot pressure to measure balance, both women aged 65 and above and young women in their 20s had a significant decrease in anterior foot pressure, and a significant increase in posterior foot pressure (p< 0.05). Conclusion: The results of this study did not positively affect the vital capacity of elderly women with FHP. However, the significant increase in vital capacity of young women in their 20s suggests that contraction of the abdominal muscle is necessary during forced expiration. Therefore, it is believed that proper application and therapeutic interventions should be combined when applying Figure-8 brace

“…Han et al 12 ) studied a normal posture group and a forward head posture group and found that FVC, FEV1, and maximum voluntary ventilation (MVV) were all decreased in the forward head posture group. According to Lee and Chu 13 ) , there were positive correlations between the CVA and oxygen uptake and CO 2 emission, which indicates that respiratory activity decreases as the angle of the forward head posture is reduced.…”

[Purpose] The purpose of this study is to determine the effect that secondary postural deformities and chronic postural abnormalities have on lung capacity, as well as correlate the activity of the respiratory muscles. The results provide basic objective data about the forward head posture and respiratory muscle activity that can be used in clinical situations. [Subjects and Methods] The subjects used in this study were 24 patients aged 25 to 35 years old who visited a hospital in Jeollanam-do Province, Korea, between September 2015 and January 2016. The patients were diagnosed with forward head posture because the vertical line between the acromion process and the external acoustic meatus was at least 5 cm. We measured the craniovertebral angle, pulmonary functions, and respiratory muscle activity of the subjects for correlation analysis. [Results] A positive correlation was found between the craniovertebral angle and the forced vital capacity (r=0.63), while a negative correlation was found between the craniovertebral angle and the sternocleidomastoid muscle (r=–0.77). The craniovertebral angle and the anterior scalene muscle showed a negative correlation (r=–0.65). There were positive correlations between the forced vital capacity and the sternocleidomastoid muscle (r=0.71), and between the forced vital capacity and the anterior scalene muscle (r=0.59). [Conclusion] Severe forward head posture increased the activities of the sternocleidomastoid muscles and the anterior scalene muscles, and decreased the forced vital capacity. Thus, it is necessary to develop more efficient interventions for managing forward head posture based on pulmonary function and the activity of the respiratory synergist muscles.
