Electromechanical Delay of the Knee Flexor Muscles After Harvesting the Hamstrings for Anterior Cruciate Ligament Reconstruction.

Although the EMD of ST and BF was significantly increased due to fatigue, as expected, their synchronization pattern as identified by the difference in their EMDs remained the same. Thus, the reconstructed knee responded in a balanced manner and the hamstrings firing pattern remained the same, despite the intervention to the ST tendon.
