A new 4-item core stability (CS) test battery was developed. For reliable results in future research, administer the test over 3 days, using day 3 data as the best estimate of core stability.

Area of Science:

  • Sports Medicine
  • Rehabilitation Science
  • Biomechanical Research

Background:

  • Core stability (CS) is crucial for athletic performance and injury rehabilitation.
  • Standardized and reliable CS testing is needed for accurate assessment in research and clinical settings.

Purpose of the Study:

  • To develop a reliable 4-item test battery for assessing core stability.
  • To establish an optimal measurement schedule for maximizing test-retest reliability and internal consistency.

Main Methods:

  • Development of a 4-item core stability test battery based on established training and rehabilitation protocols.
  • Systematic administration of the test battery over multiple days to assess reliability.
  • Statistical analysis using intraclass correlation coefficients (ICCs) and stability reliability coefficients.

Main Results:

  • The 4-item CS test battery demonstrated high reliability.
  • Intraclass correlation coefficients generally exceeded 0.90 across test administrations.
  • Stability reliability coefficients exceeded 0.90 for two tests and 0.80 for the other two by the third and fourth days of testing.

Conclusions:

  • The developed 4-item core stability test battery is a reliable tool for research.
  • Administering the test battery over at least 3 days is recommended for optimal reliability.
  • Data from the third day of testing provides the most accurate estimate of an individual's core stability.
