The Star Excursion Balance Test (SEBT) is an essential tool for assessing balance, especially in clinical and athletic settings. By evaluating how well a person can maintain stability while reaching in various directions on one leg, the SEBT identifies balance deficits that can lead to injuries. This is especially important for athletes who often face dynamic movements in their sports. In this post, we will uncover what the SEBT entails, why it matters, how to perform it, and how to make sense of the results.
Understanding the Importance of Balance
Balance is vital for nearly every physical activity, from walking to competitive sports. In fact, a study published in the Journal of Sports Medicine found that good balance can reduce the risk of falls by nearly 30%. Poor balance can not only increase the likelihood of injuries but also hinder athletic performance.
The SEBT helps assess dynamic balance, which is our ability to stay stable while moving. This skill is crucial for athletes who frequently change direction, like soccer players, basketball players, or gymnasts. By recognizing the significance of balance, we can understand the true value of the SEBT for both assessment and training.
What is the Star Excursion Balance Test?
The SEBT evaluates a person’s balance and stability through a series of reaching tasks while standing on one leg. The test incorporates eight reach directions:
Anterior (forward)
Anteromedial (forward and to the side)
Medial (to the side)
Posteromedial (backward and to the side)
Posterior (backward)
Posterolateral (backward and to the side)
Lateral (to the side)
Anterolateral (forward and to the side)
Each reach direction is measured to determine how far the individual can extend without losing balance. The results provide critical insights into potential balance issues and can guide training or rehabilitation efforts.
How to Perform the SEBT
Equipment Needed
To conduct the SEBT, gather these items:
A measuring tape or ruler
Tape or chalk for marking the starting point
A flat, non-slip surface
Optional: A protractor or goniometer for angle measurements
Test Setup
Mark the Center Point: Use tape or chalk to create a central point on the ground where the test will start.
Create Reach Directions: From the center point, measure out and mark lines at 45-degree angles to indicate the eight reach directions. Each line should extend about 90 cm (35 inches) from the center.
Warm-Up: It's vital that the individual warms up properly to prepare their muscles and joints before the evaluation.
Test Procedure
Single-Leg Stance: The individual stands on one leg, lifting the opposite leg off the ground.
Reaching: While maintaining balance, the individual reaches as far as possible along each marked line without losing stability or touching the ground with the lifted leg.
Recording Results: Measure the distance reached for each direction. Ideally, the test should be performed three times for each direction, recording the best score.
Switch Legs: After testing one leg, repeat the process with the opposite leg.

Safety Considerations
Ensure the testing area is clear and safe. Having a spotter nearby can help individuals who may struggle to balance.
Interpreting the Results
The SEBT results are valuable indicators of a person's balance abilities.
Scoring
Scores are usually calculated as a percentage of the maximum reach distance. For example, if the farthest reach in the anterior direction is 70 cm, and the maximum goal was 90 cm, the score would be calculated as follows: (70/90) * 100 = 77.78%.
Identifying Deficits
Analyzing scores from different directions can reveal specific balance weaknesses. For instance, if someone scores lower in the posterior direction than in the anterior, it suggests a potential instability in that area.
Clinical Relevance
In rehab settings, the SEBT can track recovery. Athletes can use the scores to tailor training and address specific balance deficiencies, ultimately avoiding up to 50% of injuries linked to poor balance.
Benefits of the SEBT
The SEBT is advantageous for various reasons, making it a preferred choice among trainers and clinicians.
Comprehensive Assessment
This test evaluates balance in multiple directions, providing a holistic perspective on stability. This multidirectional focus is particularly useful for athletes who often use a range of movements in their sports.
Easy to Administer
The SEBT is straightforward to conduct and doesn’t require specialized equipment. This accessibility makes it suitable for clinics, gyms, and training facilities.
Identifying Injury Risk
By pinpointing balance weaknesses, the SEBT can help forecast injury risks. Studies indicate that athletes with poor balance are twice as likely to suffer injuries, underscoring the importance of this assessment.
Enhancing Performance
Targeted training based on SEBT results can boost athletic performance. Improved balance enhances agility, coordination, and overall control during sports activities.
Training for Improved Balance
If the SEBT indicates balance deficiencies, incorporating specific training exercises becomes necessary.
Balance Exercises
Single-Leg Stands: Stand on one leg for as long as possible. To increase difficulty, close your eyes or use an unstable surface.
Dynamic Movements: Engage in activities that require quick direction changes, such as lateral lunges or shuttle runs.
Balance Boards: Utilize balance boards or stability discs to enhance proprioception and stability.
Strength Training: Focus on strengthening the core, hips, and legs with exercises like squats, lunges, and deadlifts.
Progress Monitoring
Retesting with the SEBT every few weeks can help track improvements. This allows necessary adjustments to training plans and ensures continued progress.
Final Thoughts
The Star Excursion Balance Test (SEBT) is a crucial assessment tool for measuring dynamic balance and identifying potential stability issues that could lead to injuries. By learning to perform the test and interpret the results, you are better equipped to enhance your balance and stability.
Incorporating specific training based on SEBT findings can not only boost athletic performance but also lower the risk of injuries. Whether you’re an athlete, coach, or clinician, the SEBT can significantly contribute to improving balance and promoting overall physical health.
