Various trajectory generation and walking control approaches ranging from open loop walking to systems with many sensors and feedback loops have been reported in ...

OBJECTIVE Persistent weakness is a common problem after anterior cruciate ligament- (ACL-) reconstruction. This study investigated the effects of high-intensity (HRT) versus low-intensity (LRT) resistance training on leg extensor power and recovery of knee function after ACL-reconstruction. METHODS 31 males and 19 females were randomized to HRT (n = 24) or LRT (n = 26) from week 8-20 after AC...
