OBJECTIVE: To evaluate the measurement variability of quantitative sensory testing (QST) in persons with post-stroke shoulder pain. DESIGN: A test-retest design. PARTICIPANTS: Twenty-three persons with post-stroke shoulder pain (median age 65 years). METHODS: Thermal detection thresholds (cold and warm), pain thresholds (cold and heat) and mechanical pain thresholds (pressure and pin prick) were assessed twice in both arms, 2-3 weeks apart. Measurement variability was analysed with the intraclass correlation coefficient (ICC2.1), the change in mean (đ) with 95% confidence interval (logarithmic scales), and the relative standard error of measurement (SEM%Downloads
