| Introduction: Postural control is the body's innate capacity to maintain the center of gravity in the support limits. About the effects of spinal curvature on postural stability (balance), there are conflicting results and often have been considered change a special curvature only. The purpose of this study was to study postural control in individuals with sway back abnormalities.
Methods: To conduct the present study, 35 subjects with sway back posture with the average of age 20.65± 1.52 years, Weight 67.39± 12.31 kg and height 171.93±6.84 cm and 35 normal people with the average of age 20.6± 1.23 years, Weight 67.07± 11.31 kg and height 171.81±7.77 cm were selected. Side view photography and calculate the sway angle was used to select subjects with sway back posture (10 ≥). Other tools used in this study were as follows: photography and craniovertebral angle calculating for measuring the forward head displacement, dual inclinometer for measurement of kyphosis and lordosis. COP parameters were also measured by foot pressure distribution software. Pearson correlation coefficient and independent t-test in the significant level of P≤0/05 was used to analyze the collected data.
Findings: No significant differences were observed between natural subject and subjects with sway back on the forward head angle (p = 0.02), thoracic kyphosis (p =0.023), lumbar lordosis (p = 0.017) and sway angle (p=0.001). There was significant difference between COP variables of the normal and sway back subjects (p=0.02). A significant relationship was observed between anterior - posterior COP displacement and forward head angle (r=0.2), thoracic kyphosis (r=0.29), lumbar lordosis (r=0.41) and lordosis, kyphosis ratio (r=0.53) (p≤0.05).
Conclusion: As a result, it appears that the spinal abnormalities in the subjects with sway back posture can cause poor postural control. |
