Technical validity, concurrent validity, reliability, and treatment sensitivity of an innovative low-cost pain algometer in healthy adults and patients with discogenic sciatica.

Researchers evaluated a novel low-cost pressure pain algometer by testing its technical validity, concurrent validity, reliability, and treatment sensitivity in both healthy adults and patients with discogenic sciatica. The device demonstrated acceptable measurement properties when compared to established reference standards, suggesting it may serve as an accessible tool for quantifying pressure pain thresholds in clinical and research settings. These findings are relevant to PTs who use pressure algometry for pain assessment and monitoring treatment outcomes.
