Absolute and relative reliability of Pressure Pain Threshold (PPT) assessment in patients with nonspecific shoulder pain.

ABSTRACT: This study investigates the intra- and interrater reliability of Pressure Pain Threshold assessments in patients with nonspecific shoulder pain, focusing on chronic and subacute stages. A sample of 26 adults was evaluated using a mechanical algometer across six anatomical points. Intrarater and interrater reliability were calculated using the intraclass correlation coefficient (ICC), standard error of measurement, and minimal detectable change (MDC). Results demonstrated almost perfect reliability for both intrarater (ICC range: 0.96-0.99) and interrater (ICC range: 0.92-0.99) assessments. Standard error of measurement and MDC values for intrarater reliability showed clinically acceptable error, except for the upper trapezius and mid-deltoid, where MDC value exceeded 25% of the grand mean,
