Comparing the reliability of the single leg squat test using two, three, and four category ordinal rating scales.

ABSTRACT:

Background

The single-leg squat test (SLST) is supported by evidence for reliability and validity across various visual rating methods, but the optimal number of ordinal categories for assessing movement quality remains unclear. The study aims to determine the most informative and reliable number of ordinal scoring categories for visually rating the SLST.

Methods

A total of 58 subjects with lower extremity injuries participated. A single therapist rated the SLST with a 1-week interval to establish intra-rater reliability. Two therapists independently rated the SLST at the same time point to establish inter-rater reliability. Two-, three-, and four-category ordinal scales were simultaneously used to evaluate SLST performance in rating the components of trunk deviation, hip ad
