A Systematic Review of the Star Excursion Balance Test to Define Clinically Meaningful Psychometric Values.

Area of Science:

• Biomechanics
• Sports Medicine
• Rehabilitation Science

Background:

• The Star Excursion Balance Test (SEBT) is a widely used tool for evaluating lower extremity strength, range of motion, balance, and functional performance.
• Existing evidence supports the SEBT's utility, but a comprehensive review of its psychometric properties is needed for clinical application.

Purpose of the Study:

• To systematically review and define clinically relevant psychometric values for the SEBT.
• To consolidate evidence on the reliability, validity, and responsiveness of the SEBT.

Main Methods:

• A systematic review of studies reporting SEBT reliability, validity, and responsiveness was conducted.
• Searches were performed across multiple databases (PubMed, Embase, Medline, CINAHL, SPORTDiscus, Scopus) up to November 2023.
• Data extracted included intra-class correlation coefficients (ICC), minimal detectable difference (MDD), minimal detectable change (MDC), and minimal clinically important difference (MCID).

Main Results:

• 102 studies were included, analyzing SEBT reliability (ICC: 0.51-0.99) and validity.
• SEBT demonstrated ability to differentiate between healthy individuals and those with lower extremity injuries, correlating with various outcome measures.
• Responsiveness data identified MCID values ranging from 4.2 cm to 10.9 cm within two weeks post-ACL reconstruction.

Conclusions:

• The SEBT exhibits acceptable reliability and validity for clinical use.
• Established psychometric values (MDD, MDC, MCID) enhance the SEBT's clinical relevance and application in patient assessment and monitoring.
• Standardized protocols derived from this review can improve SEBT's consistent application.
