The interexaminer reliability of relative leg-length evaluation was studied on a sample of 30 subjects by examiners. Prone leg length was examined categorically, whether heels were even or whether there was a relative shortness to either side. Relative leg-length differences were estimated by using a ruler. Concordance was computed using Kappa and intra-class correlation coefficients. The Kappa statistic yielded “fair” to “good” concordance (ranges: 0.31-0.75) among the 6 combinations of examiner pairs. The results support the reliability of observing and measuring relative leg- length inequality in the prone position, and are intended to establish a baseline for future investigation.
