About this study
Official title: Does The Static Q Angle Reflect The Dynamic Landing Mechanics? Relationships Between Q Angle, FPPA, LESS, And Body Composition In Young Female Athletes
This study aimed to investigate whether static Q angle reflects dynamic landing mechanics in young female athletes.
Read the detailed description
The purpose of this study was to examine the relationship between static Q angle and dynamic landing mechanics in young female athletes. Twenty-four physically active young female athletes voluntarily participated in the study.
Static Q angle measurements were obtained using digital image analysis techniques. Dynamic landing mechanics were assessed using the Landing Error Scoring System (LESS) and frontal plane projection angle (FPPA) measurements during a standardized drop vertical jump task.Body composition variables including body fat percentage, muscle percentage, and fat-free mass were also evaluated. Correlation, regression, and ROC analyses were performed to determine the association between static anatomical alignment and dynamic knee valgus mechanics. The study aimed to determine whether increased static Q angle values are associated with altered landing biomechanics and increased injury risk indicators.

Where is the study taking place?
The record lists 1 site in Turkey (Türkiye). Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Frontal Plane Projection Angle (FPPA) (time frame: Baseline). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
