Work of flexion during triggering

The graph depicts the work of complete finger flexion through excursion of the flexor digitorum profundus tendon from 0 to 30 mm. The 5 lines indicate 5 identical trials of the same condition. The load exerted on the tendon rises sharply until approximately 23 mm, then experiences a sharp dip, then rises again at approximately the same slope as before, indicating that triggering occurred. TNC, tension normalized by circumference.
