Abstract

This study investigated whether peak joint angles during clinical lower extremity functional tests (Small Knee Bend [SKB], Single Leg SKB, Lunge and Hop Lunge) were related to peak angles during more dynamic landing tasks (Running and Drop Jump). Peak three-dimensional angles were quantified for each movement for 25 uninjured adults (22 ±4 years) and 23 uninjured young athletes (11 ±1 years) using a nine camera motion analysis system. In young athletes Pearson correlations between SKB and Drop Jump were moderate to very large (r=0.39 to 0.87). In adults and young athletes correlations between SKB, Single Leg SKB, Lunge and Hop Lunge with Running were moderate to very large (r=0.45 to 0.90). Clinical lower extremity functional screening tests are useful for estimating dynamic lower extremity alignment in adults and young athletes.
