Gender differences in core strength and lower extremity function during the single-leg squat test

This chapter discusses the principles of core stability in terms of its importance on lower extremity function. The use of the single-leg squat test to measure core stability is described, which is a practical tool that can easily be used in the clinical setting. The test protocol and methods for interpretation of the results are provided. Reliability and validity data are cited. Associations between core strength, neuromuscular activity, and lower extremity function during the test are described. Differences in core strength, lower limb position, and posture between male and female subjects depicted by the single-leg squat are summarized.
