Muscle Weakness After Anterior Cruciate Ligament Reconstruction
Conditions
Brief summary
The main aims of the study are (1) to examine the impact of contralateral strength training on the quadriceps muscle function after ACL surgery and (2) to compare the magnitude of cross-education induced by NMES versus eccentric strength training.
