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.
