Fig. 7. Variations in stiffness among the five segments studied at
Po or 0.25 of Po. Stiffness declines
from the tendon to the aponeurosis, and the tendon was significantly
(P<0.05; indicated on graph) stiffer than all three regions that
did not include any overlap between tendon and aponeurosis. In addition, while
the general pattern holds for contractions at 0.25 of Po,
the tissue is much more compliant. TEND, tendon; PTDA, proximal tendon/distal
aponeurosis; DA, dorsal aponeurosis; MA, middle aponeurosis; PA, proximal
aponeurosis.
