Summary

This observational, cross-sectional study aimed to compare dynamic Q-angle, trunk/core endurance, and lower-extremity flexibility between elite adolescent female and male sprinters with and without patellofemoral pain syndrome (PFPS). Participants were classified according to sex and PFPS status. Dynamic Q-angle was assessed during a standardized step-down task, trunk endurance was evaluated using McGill flexion, extension, and lateral endurance tests, and lower-extremity flexibility was assessed using the Straight Leg Raise, Modified Thomas, and Ober tests. The study also examined whether sex and PFPS status were independently associated with dynamic Q-angle. No therapeutic or experimental intervention was administered.

Conditions

  • Patellofemoral Pain Syndrome
  • Anterior Knee Pain Syndrome

Interventions

OTHER

Patellofemoral Pain Syndrome Status

Participants were classified as having patellofemoral pain syndrome (PFPS) or not having PFPS based on a clinical assessment performed by a sports medicine physician. PFPS classification was based on anterior knee pain symptoms, positive patellofemoral clinical tests, an Anterior Knee Pain Scale score below 80, and a Visual Analog Scale pain score of at least 3. Biological sex was used as an additional grouping factor. No therapeutic, exercise, pharmacological, or experimental intervention was administered.
