  1. Data from the electromyography of m. trapezius superior and m. deltoideus anterior. Data are normalized to a maximum isometric contraction and therefore displayed as present of a reference value. Data are presented as mean and standard deviations (SD). Only 14 patients were able to perform flexion 90°. * indicates significant difference (here p = 0.021)
