Intertester reliability of judgments of the presence of trigger points in patients with low back pain.
The purpose of this study was to determine the intertester reliability of assessment s of the presence of trigger points in the region of the lumbar spine of patients with low back pain ( LBP ) . A total of six trigger points described by Travell and Simons were studied . The trigger point examination procedures described by Travell and Simons were used by 12 physical therapists . R and omly paired therapists examined 50 patients for 197 trigger points . The Kappa coefficient , percent agreement , the observed proportion of positive agreement ( Ppos ) , and the observed proportion of negative agreement ( Pneg ) were used to describe reliability . Kappa values ranged from .29 to .38 . Percent agreement ranged from 76 % to 79 % . Ppos ranged from .43 to .52 . The low Kappa and Ppos values suggest different therapists are unable to reliably determine when a trigger point is present in a patient with LBP . This study suggests the usefulness of examining for the presence of trigger points in patients with LBP should be question ed
