Brief Summary

The Lower Quadrant Y-Balance Test (LQYBT) is a landmark test used in assessing lower extremity performance, determining risk factors for injury, and making return-to-sport decisions. Studies have shown that the individual's focus of attention affects balance. The literature, has shown that the use of external focus is more effective than the use of internal focus in the execution of a movement.Consistent with these findings, the use of an external focus instruction during the LQYBT may lead to achieve more realistic and a higher performance outcome than the test result with standard instructions. The primary aim of this study was to investigate the effects of using different instructions and focusing techniques on test performance on the LQYBT. The secondary aim was to investigate the reliability of the different instructions and focus tests we used for the LQYBT. Hypothesis of the study that test performance can be further enhanced by differentiating the instructions and focus techniques. A more effective assessment of individual performance may help us to make a more realistic decision to return to sport.

Outcome Measures

Primary Outcomes (1)

• Investigate the effects of using different instructions and focusing techniques on test performance on the LQYBT.

  To ensure normalization, the average distances measured in the anterior, posteromedial, and posterolateral directions were obtained for each command, and the results were divided by the length of the leg and multiplied by 100. The total score for the dominant side in the LQYBT was determined by aggregating the average reach distance (cm) across three directions, dividing it by three times the length of the leg, and then multiplying by 100. Repeated Measures Analysis of Variance (ANOVA) was used to analyze comparisons of different instruction.

  40 minutes for each participant

Secondary Outcomes (1)

• Investigate the reliability of the different instructions and focus tests we used for the LQYBT.

  Performed 2 times in 3 days apart, 40 minutes for each participant

Interventions

Lower Quarter Y Balance Test BEHAVIORAL

The LQYBT is a widely used test for assessing lower extremity dynamic balance and neuromuscular control. Participants' lower limb balance was performed using The Y Balance Test Kit™ (Move2Perform, Evansville, IN).
