  1. Data are expressed as mean ± standard deviation (initial length – final length). The initial length was set as a reference with 100%. Δ Distance% was calculated by dividing the final and initial lengths by the initial length. The P values were calculated to compare the elevation of the coronal plane (from 20° to 120°) and horizontal adduction (from 20° to 100°)
