description Y-Balance Overview
The Y-Balance Test is a functional performance assessment derived from the Star Excursion Balance Test, widely used in sports medicine and physical therapy. The individual balances on one leg while reaching with the opposite lower limb in three specific directions—anterior, posteromedial, and posterolateral—to form a Y shape. This test measures dynamic postural control, lower extremity reach distance, and identifies asymmetries in balance or mobility.
help Y-Balance FAQ
What is the Y-Balance Test?
The Y-Balance Test is a functional balance assessment derived from the Star Excursion Balance Test. A person stands on one leg and reaches with the other leg in anterior, posteromedial, and posterolateral directions.
What does the Y-Balance Test measure?
It measures dynamic balance, reach control, and lower-limb stability while the person maintains a single-leg stance. Clinicians often compare reach distances between the right and left sides.
Is the Y-Balance Test used in physical therapy?
Yes. Sports-medicine and physical-therapy professionals use it as one part of movement and injury-risk assessment, not as a stand-alone diagnosis.
How is a Y-Balance score interpreted?
Reach distances are commonly normalized to leg length and compared across directions and sides. A score must be interpreted with the test protocol and the person's sport or rehabilitation context.
