Selective control of the proximal lower limb may be the main determinant of walking velocity. The compensatory adaptations were similar, except for pelvic motion, in stroke patients with different levels of motor recovery, whereas the poor group walked with synergistic mass patterns and reduced stability.

Stroke patients who exhibited no or low-amplitude muscle activity in the tibialis anterior, associated with premature or excessive activation of the soleus muscle in their hemiplegic limbs, when rising from a chair were prone to falling. The compensatory excessive tibialis anterior and quadriceps muscle activation in the unaffected limbs of stroke patients might have a role in preventing them from falling.
