| Abstract | ||||
| Background: Adolescent Idiopathic Scoliosis (AIS) is a prevalent spinal deformity that emerges during the adolescent growth spurt. It disrupts normal sagittal spinal alignment, which may affect posture and the function of deep cervical flexor muscles. Purpose: To examine the correlation between Cobb’s angle and forward head posture, cervical sagittal curvature, and the performance of deep cervical flexor muscles in adolescents diagnosed with idiopathic scoliosis. Methods: A cross-sectional correlational study was conducted on 34 adolescents (25 females, 9 males), aged 11–23 years, with AIS, Lenke types from 1 to 6 (single and double curves). Cobb’s angle and Sagittal Cervical Curve Angle (SCCA) were measured radiographically. Forward head posture was assessed using the Craniovertebral Angle (CVA), and deep cervical flexor muscle endurance was evaluated via the Cranio-Cervical Flexion Test (CCFT). Results: No statistically significant correlation was observed between Cobb’s angle and CVA, SCCA, or deep cervical flexor performance (p > 0.05). However, a moderate, statistically significant positive correlation was found between SCCA and both the activation score and performance pressure index from the CCFT (p < 0.01), suggesting a relationship between cervical sagittal alignment and deep neck flexor muscle performance. The average SCCA of 13.5° indicates that cervical hypolordosis was common among participants. Conclusion: There was no significant correlation between Cobb’s angle and forward head posture or deep cervical flexor performance. However, cervical sagittal curvature, especially hypolordosis, showed a significant association with muscle performance, highlighting its clinical importance in AIS assessment. | ||||
