Effect of Body Mass Index on Craniovertebral Angle and Shoulder Angle in Egyptian Adolescents

Abstract

Purpose: To explore the effect of body mass index (BMI) on Craniovertebral Angle (CVA) and Shoulder Angle (SA) in Egyptian Adolescents. Methods: Cross Sectional Study designe was used. Eighty-six physical therapy students were selected randomly, and their age were ranged from 18-27 years. They were divided into three groups according to BMI. The first group with normal BMI (18.5-24.9 Kg/m 2 ), while the second group was overweight (BMI was ranged from 25-29.9 Kg/m 2 ). The third group was obesity class I (BMI was ranged from 30-34.9 Kg/m 2 ). Photogrammetry method used (the photographic sessions by mobile phone Samsung J-7 Camera and use of Corel Draw software to analyze the pictures). Results: A significant difference was detected between normal BMI and overweight (p<0.02) and significant difference between normal BMI and obese (p<0.03). For SA there was significant difference between normal BMI and overweight (p<0.02). However, for CVA the relation between overweight and obese was not significant (p>0.2), and for SA non-significant difference between normal BMI and obese (p>0.41) and non-significant difference between overweight and obese (p>0.2). Conclusion: overweight and obesity change CVA and forward head posture and overweight changed SA and so rounded shoulder appeared. However, obesity did not change SA and rounded shoulder.

The Relationship Between Smartphone Usage Pattern and Cervical Proprioception in Adults with Text Neck Syndrome in Malaysia

“…Furthermore, the CVA correlates with higher cervical proprioception. 24,25 Right neck rotation was associated with CP in this study. Consistent with these results, previous studies showed that individuals suffering from chronic, nontraumatic cervical spine pain and cervical spondylosis had a range of motion of 6.3° in flexion, 5.2° in extension, 6.9° in right rotation, and 4.2° in left rotation of the JPE 10 .…”
