Objective The aim of this study was to compare electromyographic activities between and within the paretic nonparetic lower limb muscles during sit-to-stand (STS) task in subjects with hemiparesis as a result stroke. Design This is cross-sectional study. Results All monitored both limbs remained active most task; were activated before seat-off reached maximum peak activity after (P < 0.01). As compared limb, exhibited earlier activation hamstrings 0.01); longer period higher tibialis anterior, soleus, quadriceps ≤ 0.02). onset time similar all ≥ 0.053), whereas anterior hamstring soleus 0.015). These results illustrate that muscle impaired but level side. Conclusions Neuromuscular coordination abnormalities observed limbs. unable recruit at proper achieve amplitude for executing task, significant compensations occurred on
