Background and aims: Excessive mobile phone use increases strain on the neck, leading to muscle weakness and imbalance in the neck and shoulder girdle. This study examined the effects of corrective exercises on neck muscle length, endurance, and strength in female students with text neck syndrome. Methods: In this quasi-experimental pretest-posttest study, 70 female students aged 12–14 with text neck syndrome from Hamedan were purposefully selected and randomly divided into experimental and control groups (35 each). The experimental group underwent an eight-week corrective exercise program, while the control group received no intervention. Pectoralis minor muscle length, neck flexor and extensor strength, and endurance were measured before and after the intervention. Data were analyzed using repeated measures ANOVA and paired-sample t-tests. Results: Significant time × group interactions and paired differences were observed for pectoralis minor length, neck flexor and extensor strength, and endurance, indicating improvements in the experimental group compared to the control (p < 0.05). Conclusion: Corrective exercises enhance pectoralis minor length and neck muscle strength and endurance, mitigating forward head posture and neck pain. These exercises are recommended for students with frequent mobile phone use to improve muscular balance and alleviate symptoms of text neck syndrome.
