| Abstract Introduction: Upper crossed syndrome (UCS) is a prevalent postural disorder characterized by muscular imbalances, including shortened anterior muscles (e.g., pectoralis major and levator scapulae) and weakened posterior muscles (e.g., middle and lower trapezius)(Page et al.2010). This condition is common among wrestlers due to repetitive biomechanical loading and insufficient postural correction during training(Sepehri et al.,2024). The aim of this study was to compare the effects of eight weeks of comprehensive corrective exercises (CCE) versus dynamic neuromuscular stabilization (DNS) exercises on thoracic kyphosis angle, forward head posture (FHP), and rounded shoulders (RS) in wrestlers with UCS. Methods: Thirty elite wrestlers from Alborz Province, Iran, diagnosed with UCS (kyphosis >42°, FHP >44°, RS >49°), were randomly assigned to three groups (n=10 each): CCE, DNS, and control. Kyphosis was measured using a flexible ruler, while FHP and RS angles were assessed via digital photography and Kinovea software(Seidi et al.2020). Participants attended three supervised 60-minute sessions per week over eight weeks(Frank et al.2013). Data were analyzed using repeated-measures ANOVA in SPSS version 21 (p≤0.05). Results: Post-intervention analyses indicated significant reductions in kyphosis, FHP, and RS angles in both CCE and DNS groups (p<0.05), with no significant changes observed in the control group. Between-group comparisons demonstrated superior improvements in the CCE group compared to DNS and control (p<0.05), with larger effect sizes for CCE (kyphosis: η²=0.62; FHP: η²=0.58; RS: η²=0.55). Conclusion: CCE demonstrated greater efficacy than DNS in improving UCS-related postural abnormalities among wrestlers. Incorporating CCE into training routines may effectively correct postural imbalances, enhance functional performance, and reduce injury risk. |
