Reliability
Acceptable intra-rater reliability was determined
through analysis of pre- to post-control measures of
ROM and PPT. For this study the intra-class correlation
coefficient (ICC 2,1) and standard error of the
measurement (SEM) for ROMwere estimated to be 0.98
and 1.331 respectively. The ICC 2,1 and the SEM for
PPT were estimated to be 0.96 and 10.7 kPa respectively.
This indicates that both the size of the error (SEM) and
the ICC are indicative of reliable measures.
