Fig. 2. Relationship between fiber length and joint angle measured radiographically
without (AC) and with (DF) sarcomere length normalization. (A)
Tibialis anterior (TA) raw fiber length vs ankle angle, (B) Extensor
digitorum longus (EDL) raw fiber length vs ankle angle, (C) Soleus
raw fiber length vs ankle angle, (D) TA normalized fiber length
vs ankle angle, (E) EDL normalized fiber length vs ankle
angle, (F) Soleus normalized fiber length vs ankle angle. Regression
relationships in A, B and C were statistically significant while those in D, E
and F were not. See text for details.
