Ward et al. dissected 27 muscles from 21 cadaveric lower extremities to generate a high-resolution architectural dataset — measuring fiber length, PCSA, pennation angle, and sarcomere length — to replace prior models built on only five specimens of unknown demographics and without sarcomere length normalization.
When planning lower extremity tendon transfers, use this dataset to match donor and recipient muscle architecture — fiber length for excursion compatibility and PCSA for force matching.
When modeling or interpreting gait data, remember that the soleus (not gastrocnemius) dominates plantarflexion force, and that hamstrings and quadriceps are equally designed for excursion, not opposites.
