Main Outcome Measure: The diagnostic accuracy was calculated for sEMG parameter
23
reliability, precision and ability to differentiate subjects with and without PFPS. The
24
selected sEMG parameter associated with anterior knee pain was considered as an index
25
test and was compared with the reference standard for the diagnosis of PFPS. Intraclass
26
correlation coefficient (ICC), standard error of measurement (SEM), independent t-tests,
27
sensitivity, specificity, negative and positive likelihood ratios (LR- and LR+) and
28
negative and positive predictive values (NPV and PPV) were used for the statistical
29
analysis.
