Figure 2.

(A, B) Isokinetic testing of the left shoulder in 45° of abduction in the scapular plane and the elbow placed in neutral position and flexed at 90°. (C) Sequence in concentric mode with 5 repetitions at 240 deg/s indicating the torque (N·m) of each repetition in relation to time (left figure) and arc of motion (right figure). The red line indicates the torque of internal rotation, and the blue line indicates recovery during external rotation. (D) Peak torque per repetition during fatigue testing with 20 repetitions at 180 deg/s in concentric mode. The green and red lines indicate the internal rotation of the affected and healthy contralateral shoulders, respectively.
