Comparison of Lower Extremity Alignment among Taekwondo Athletes of Various Subdisciplines.

Studies analyzing lower extremity alignment (LEA) LEA among taekwondo subdisciplines athletes are lacking. This study compared LEA in the dominant and nondominant legs intaekwondo athletes. Twelve measurements of LEA were analyzed for 157 athletes (63 sparring, 50 demonstration, and 44 poomsae athletes) registered with the Korea Taekwondo Association.

Landing biomechanics in anterior cruciate ligament reconstructed females who pass or fail a functional test battery.

Background: A functional test battery (FTB) has been proposed to determine return to full activity following anterior cruciate ligament reconstruction (ACLR). However, there is little biomechanical evidence of FTB usefulness. The purpose of this study was to compare knee joint landing and cutting biomechanics between ACLR patients who passed (ACLR-Pass), failed (ACLR-Fail), and healthy females (Healthy) before and after exercise.

Normalization influences knee abduction moment results: Could it influence ACL-injury research, too?

Objectives: Normalization of joint moments to reduce anthropometric influences prior to making group comparisons is a widely-accepted practice. However, a seminal prospective study reported greater non-normalized knee abduction moment (KAM) in nine females who subsequently sustained an ACL injury. It is not clear if this finding may have been influenced by the fact that the ACL-injured females were on average 3.
