Overview

Supports reliable group-level pain assessment in young adults; leaves open individual-level clinical utility due to variation.

Structured PICO

P
Population
10 healthy volunteers aged 18-25 (mean age 21, 40% male) with no current or previous major medical or psychiatric condition, and no spontaneous or chronic pain complaints.
I
Intervention
Pressure algometry and ice placed at the hand and head (test-retest assessments 10 minutes apart)
O
Outcome
Reliability of pressure and thermal (cold) pain threshold assessment using intra-class correlation (ICC), coefficients of repeatability (CR), and variability (CV)

Pressure algometry and strategically placed ice are reliable techniques for assessing pain processing in young adults, though complementary estimation of CR and CV is recommended due to inter-individual variation.

Limitations

  • Small sample size (n=10)
  • Large intra-individual variability in repeated pain threshold assessments which may have inflated the ICCs
  • Possibility of systematic over-estimation by the investigator of the actual application rate applied during testing
