BACKGROUND: Scapular stabilization exercises can improve forward shoulder posture in young women. However, the effects of optimal exercise protocols on neck and shoulder postures, scapular muscle imbalance and thoracic kyphosis are still unclear. OBJECTIVES: To investigate the effects of scapular stabilization exercises on neck and shoulder postures, scapular muscle imbalance and thoracic kyphosis in young women with upper crossed syndrome. METHODS: Thirty nine women aged 1,825 years with upper crossed syndrome were recruited. Participants were randomly allocated into two groups. The exercise group performed scapular stabilization exercises using elastic bands at 10 repetitions/set, 3 setsday, and 3 days/week for 4 weeks. The control group did not perform any exercises during the experimental period. The cervical and shoulder angles were evaluated using the Kinovea program. A caliper, handheld dynamometer and flexi ruler were used to evaluate the length of the pectoralis minor, strength of the scapular stabilizer muscles and degree of the mid-thoracic curve, respectively. RESULTS: The exercise group showed significant differences (p < 0.05) in the increase in cervical and shoulder angle, length of the pectoralis minor, and strength of the scapular muscles, except in the degree of mid-thoracic curve compared to the control group. CONCLUSION: This study indicated that scapular stabilization exercises can improve forward head and shoulder posture, increase the flexibility of the pectoralis minor and strengthen the scapular muscles.
