Observational Ratings of Frontal Plane Knee Position Are Related to the Frontal Plane Projection Angle but Not the Knee Abduction Angle During a Step-down Task (original) (raw)

The study analyzes the relationship between observational ratings of frontal plane knee position and two measures: the knee abduction angle (KAA) and the frontal plane projection angle (FPPA) during a step-down task performed by female collegiate athletes. A total of 81 participants were assessed, with observational ratings categorizing them into good, fair, or poor based on knee positioning. Results revealed no significant difference in KAA among the groups, while FPPA values significantly varied, indicating that observational ratings are a suitable clinical tool for screening FPPA but not KAA. This highlights the importance of using FPPA in clinical settings while assessing risk for knee injuries.
