It has become common for physiotherapists to report the reliability of the measurements they have used in a study or to report the reliability of new measurement procedures they are promoting. While this is a welcome trend in physiotherapy research, some of the approaches used in these studies to document the reliability of measurement procedures are less useful than others. In particular the use of the t test and Pearson's product moment correlation can give misleading results when used as reliability indexes. This short report will highlight some of the problems with these statistics and suggest their discontinuation as reliability indexes.
