The purpose of this study was to investigate the effects of leg lifting on the anterior and upper trapezius muscles when scapula protraction exercise was performed in a prone bridge exercise posture, which is a common waist stabilization exercise for a subject with a winged scapula. In total, 20 normal adults and 20 subjects with a winged scapula participated in the experiment. Surface EMG recordings were collected from the upper trapezius muscle and anterior muscle during a scapula protraction exercise. The status of the scapula was measured using an electronic digital caliper for the lifted distance of the scapula medial border during a backward movement. In both groups, with both legs supporting, the dominant leg was lifted, and then the non‐dominant leg was lifted, while simultaneously, scapula protraction was performed in the prone bridge exercise posture. Two‐way analysis of variance (ANOVA) measures were used to compare muscle activity differences between the two groups with respect to leg lift differences. In addition, two‐way ANOVA was used to compare the condition of each group. To investigate the differences between the groups, the Bonferroni correction was used (significance level α = 0.017). The statistical significance level α was 0.05. The results revealed that the winged scapula group showed a significant decrease in the muscle activity ratio of the anterior and upper trapezius muscles compared to the control subjects, and the muscle activity of the upper trapezius muscle increased significantly. There was no significant difference in muscle activity between the anterior and upper trapezius muscles regarding differences in leg lifting. However, in the winged scapula group, there was a significant increase when the dominant leg was lifted. In addition, high muscle activity was observed in the anterior muscle of the dominant side during dominant leg lifting. In conclusion, lifting the side leg while simultaneously performing the scapula protraction exercise to strengthen the anterior muscle can be suggested as the most effective exercise for subjects with a winged scapula.
