Patellar tendon stress between two variations of the forward step lunge

摘要

BackgroundPatellar tendinopathy (PT) or “jumper's knee” is generally found in active populations that perform jumping activities. Graded exposure of patellar tendon stress through functional exercise has been demonstrated to be effective for the treatment of PT. However, no studies have compared how anterior knee displacement variations during the commonly performed forward step lunge (FSL) affect patellar tendon stress.
