Y Balance Test (Lower Quarter)

The Y Balance Test is a dynamic assessment that measures strength, flexibility, core control, and proprioception in a single-leg stance. It is widely used to evaluate physical performance, identify functional symmetry, and identify athletes at a higher risk of lower extremity injuries. This article focuses on the Lower Quarter version of the Y Balance Test, which specifically assesses active balance and core control.


The purpose of the Y Balance Test is to assess an individual’s active balance and core control. By measuring the ability to maintain single-leg balance while reaching as far as possible in three different directions, this test provides valuable insights into an individual’s overall balance and stability.

Equipment Required

To perform the Y Balance Test, you will need a Y-Balance Test Kit and a tape measure. These tools are essential for accurately measuring the reach distance and calculating the results.


The Y Balance Test consists of six tests, performed on each leg. The three movement directions are anterior, posteromedial, and posterolateral. The tests are to be conducted in the following order:

  • Right Anterior Reach
  • Left Anterior Reach
  • Right Posteromedial Reach
  • Left Posteromedial Reach
  • Right Posterolateral Reach
  • Left Posterolateral Reach


During the Y Balance Test, the subject stands on one leg at the stance plate, with the toes of the foot positioned at the red line. The non-stance foot is placed lightly just behind the plate. The subject then reaches with the free foot in the desired direction, pushing the reach indicator as far as they can while maintaining balance. It is important that the free foot is returned to the starting position under control, without touching down or gaining support from the reach indicator.

All measurements during the Y Balance Test are taken from the red line on the stance plate, to the nearest 0.5 cm. The distance reached is recorded for each test, and the maximum reach in each direction is used to calculate a “composite reach distance.” This calculation takes limb length into consideration and provides an overall measure of balance. Additionally, the results can be compared between the two legs to assess any asymmetry.

Credibility and References

The Y Balance Test has been widely used in various sports and athletic assessments. Research studies, such as the one conducted by Shaffer et al., have confirmed the reliability of this test. It is important to note that the Y Balance Test was added to the test protocols for the NHL Combine in 2015, further highlighting its significance in evaluating athletes’ physical performance.
