Response to Letter to the Editor: Reliability of lumbar movement dysfunction tests for chronic low back pain patients; Methodological concerns to avoid misinterpretation

We are pleased to have the opportunity to respond to the letter to the editor from Prof. Dr. S. Sabour regarding our recent publication (Bauer et al., 2016). We will attempt to address the issues raised in this letter. Our study assessed the reliability of interval-scaled outcome measures of eleven different movement dysfunction tests (Bauer et al. 2016). As stated by Prof. S. Sabour, the reproducibility of such outcome measures is generally quantified by intraclass correlation (ICC) coefficients.
