Data presented as mean ± SD unless otherwise indicated.

^*Pain rating of the 10th algometer pulse before cuff inflation;

^†Pain rating of 10th algometer pulse during cuff inflation;

^‡10th minus first algometer pulse rating before heterotopic cuff inflation;

^§10th minus first algometer pulse rating during heterotopic cuff inflation;

^¶10th algometer pulse rating before heterotopic cuff inflation minus 10th algometer pulse rating during heterotopic cuff inflation. CR Coefficient of repeatability within session, equal to 2(SD of the mean time 1 [T1] to time 2 [T2] difference). ICC Intraclass correlation coefficient
