Experimental
Experimental
Sham Comparator
Arm Label
NMES
eccentric training
sham NMES
Arm Description
neuromuscular electrical stimulation (NMES) of the quadriceps muscle with Kneehab
unilateral eccentric resistance exercises
neuromuscular electrical stimulation of the quadriceps muscle with intensity which causes no visible contraction or displacement of the leg (activation below motor threshold)
Outcomes
Primary Outcome Measures
Change in bilateral quadriceps muscle strength [Nm]
Change in quadriceps muscle activation
Secondary Outcome Measures
Change in muscle architecture
Change in self-reported questionnaire outcomes (KOOS, WOMAClk)
functional test outcomes
Assessment of present functional status by means of hop tests

5. Study Description
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.
