Methodological study demonstrates refined age stratification and group comparison techniques in sensory testing cohorts, highlighting improved standardization for neuropathic pain assessments.

Key Points

To refine age-related reference standards for quantitative sensory testing (QST) and develop an accessible statistical method for comparing patient groups to normative reference data.
Applied a moving average across age groups to construct decade-specific reference standards from the German Research Network on Neuropathic Pain (DFNS) database.
Evaluated individual deviations via site-, gender-, and age-specific z-score transformations.
Conducted simulations across multiple sample sizes and variances to evaluate paired t-tests against fixed means versus non-paired t-tests against matched reference cohorts.
Women showed consistently higher sensitivity to heat pain across all ages, whereas pressure pain thresholds converged and punctate mechanical pain thresholds diverged with advancing age.
Statistical simulations indicated that the non-paired t-test approach (Method B) provided a more conservative comparison than the paired t-test against a fixed mean (Method A).
Established a simplified calculation method for z-normalized group data that enables researchers to benchmark patient cohorts against the DFNS database without subsampling raw reference records.
