Other related information
The gastrocnemius, soleus, and tibialis anterior muscle activities during stretching of triceps surae muscle are assessed by surface electromyography. Furthermore, we assess electrophysiological tests of spinal reflexes (reciprocal and presynaptic inhibition). We assess the correlation between muscle contraction status during stretching and spinal reflexes.
