This study evaluated the short- and long-term reliability of selected QSTs. Methods: Twenty healthy women participated in three experimental sessions: Baseline, 2 weeks, and 6 months. Measurements included pressure pain thresholds (PPT) in the neck, upper back, and leg; Pressure-cuff pain tolerance around the upper-arm; conditioned pain modulation during a pressure-cuff stimulus; and referred pain following a suprathreshold pressure stimulation. Intraclass correlation coefficients (ICC) and minimum detectable change (MDC) were calculated. Results: Reliability for PPT was excellent for all sites at 2 weeks (ICC, 0.96–0.99; MDC, 22–55 kPa) and from good to excellent at 6 months (ICC, 0.88–0.95; MDC, 47–91 kPa). ICC for pressure-cuff pain tolerance indicated excellent reliability at both times (0.91–0.97). For conditioned pain modulation, reliability was moderate for all sites at 2 weeks (ICC, 0.57–0.74; MDC, 24%–35%), while it was moderate at the neck (ICC, 0.54; MDC, 27%) and poor at the upper back and leg at 6 months. ICC for referred pain areas was excellent at 2 weeks (0.90) and good at 6 months (0.86). Conclusions: PPT, pressure pain tolerance, and pressure-induced referred pain should be considered reliable procedures to assess the pain-sensory profile over time. In contrast, conditioned pain modulation was shown to be unstable. Future studies prospectively analyzing the pain-sensory profile will be able to better calculate appropriate sample sizes.2023http://zaguan.unizar.es/record/12623210.3344/kjp.23011http://zaguan.unizar.es/record/126232oai:zaguan.unizar.es:126232info:eu-repo/grantAgreement/ES/FPI/CPB09-2018info:eu-repo/grantAgreement/ES/MCIU/FPU19-05237Korean Journal of Pain 36, 2 (2023), 173-183by-nchttp://creativecommons.org/licenses/by-nc/3.0/es/info:eu-repo/semantics/openAccess
