Table 3 Electromyography during isometric abduction, isometric and dynamic flexion

From: Enhanced function and quality of life following 5 months of exercise therapy for patients with irreparable rotator cuff tears – an intervention study

  m. trapezius - mean (SD) m. deltoideus – mean (SD)
Baseline 5 months Baseline 5 months
Abduction 138.1 (182.2) 147.2 (179.1) 123.8 (60.2) 141.0 (88.8)
Flexion 45° 108.4 (127.2) 313.6 (909.2) 134.8 (81.2) 117.0 (83.0)
Flexion 90° 169.9 (213.9) 179.4 (158.3) 138.1 (32.7) 109.8 (27.2)*
Dynamic flexion 130.2 (184.2) 147.4 (163.3) 108.1 (52.8) 110.5 (54.8)
  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)
