Comparing the effects of Pilates, corrective exercises, and Alexander’s technique on upper cross syndrome among adolescent girls student (ages 13–16): a six-week study

Abstract Introduction Upper Cross Syndrome is a pattern of muscle imbalance and postural dysfunction that can cause discomfort and pain. This study’s objective was to compare the effects of Pilates exercises, corrective exercises, and Alexander’s technique on upper cross syndrome in adolescent girls aged 13–16 years: a six-week intervention study. Methods The present study was Quasi-experimental, and its statistical population consisted of 13 to 16-year-old female students. Forty-five students who were diagnosed with upper cross syndrome were purposefully selected as samples and randomly assigned to three groups: Pilates exercises ( N = 15), corrective exercises ( N = 15), and Alexander’s technique ( N = 15). The participants performed exercises for 60 min per session, three sessions per week, and six weeks. This study’s objective was to compare the effects of Pilates exercises, corrective exercises, and Alexander’s technique on upper cross syndrome in adolescent girls aged 13–16 years: a six-week intervention study. This study was retrospectively registered in the Iranian Registry of Clinical Trials (IRCT) on 2023-09-19 to comply with the journal’s policies. The assigned trial registration number is IRCT20230810059106N1. Results The results of the dependent t-test showed significant decreases in forward head angle ( p = 0.0001), rounded shoulder ( p = 0.001), and kyphosis ( p = 0.0001) as a result of corrective exercises. There were also significant decreases in forward head angle ( p = 0.0001), rounded shoulder ( p = 0.002), and kyphosis ( p = 0.001) after six weeks of practising Alexander’s technique. However, in the case of Pilates exercises, a significant decrease in forward head angle ( p = 0.110), rounded shoulder ( p = 0.598), and kyphosis ( p = 0.371) was not observed. The one-way analysis of variance revealed a significant difference in the forward head angle ( p = 0.012), rounded shoulders ( p = 0.013), and kyphosis ( p = 0.009). Conclusions The effect of Alexander’s technique and corrective exercises on forward head angle, rounded shoulder, and kyphosis abnormalities was almost similar and more effective than pilates exercises.
