The Relationship Between Lower Extremity Musculature Strength, Q-angle, and Single-Leg Balance. -- In Proceedings: 10th Annual Symposium on Graduate Research and Scholarly Projects.

The purpose of this study was to examine the relationship between quadriceps angle of the lower leg, hip strength (measured by dynamometry), and balance (measured by Star Excursion Balance testing). Studies have shown that lower extremity alignment has an effect on both muscle strength and balance. However, there is a lack of research on how quadriceps angle, hip strength, and balance relate to one another. Data from 31 healthy participants between 20 and 30 years old was analyzed. Results suggest that hip flexion and hip abduction strength in males is correlated with larger quadriceps angles. Hip flexion strength was also correlated to Star Excursion performance in females. This may have important implications for lower extremity injury screening and rehabilitation interventions.
