- Muscle Activity During Gait
- Discussion:
- during last portion of single limb stance & entirety of wt release, tibial external rotation continues, ankle plantar flexion is seen, and sub-
talar joint continues to invert;
- forefoot is now in a less pronated position;
- thru action of the windlass effect, intrinsic muscle activity, and posterior tibial activity, foot increases its rigidity and acts as rigid lever to
prepare for toe off;
- gastroc-soleus muscle activity has stopped;
- elasticity of musculotendinous complex acts against rigid lever of foot still in contact with the ground;
- limb is being unloaded so that the elastic recoil allows the ankle plantarflexion;
- this transfers energy to the limb to assist knee flexion in preparation for the swing phase of gait
