Leg Muscle Activation Patterns of Sit-to-Stand Movement in Stroke Patients

Abstract

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.
