Summary
The Star Excursion Balance Test (SEBT) may be shortened without losing information on dynamic postural control. Hip and knee movements explain most of the reach distance variance in the SEBT.
Area of Science:
- Biomechanics
- Kinesiology
- Sports Medicine
Background:
- The Star Excursion Balance Test (SEBT) involves 8 reach directions, potentially measuring redundant functional components.
- This redundancy suggests the SEBT might be shortened without compromising dynamic postural control assessment.
Purpose of the Study:
- To investigate if stance-leg angular displacement relative to normalized reach distance contributes to measurement redundancy in the SEBT.
- To identify potential reductions in SEBT reach directions.
Main Methods:
- Employed a single-session, within-subjects design in an athletic training research laboratory.
- Included 10 women and 10 men, measuring normalized reach distance and angular displacement at the hip and knee.
Main Results:
- Stepwise regression analysis indicated that hip and knee flexion movements explained 62% to 95% of the variance in reach distances.
- Both individual and combined hip and knee flexion were significant predictors.
Conclusions:
- The observed redundancy in the SEBT can be attributed to the similar functional contributions of lower extremity movements.
- Findings support the potential for a more concise SEBT protocol.
