Demographic/anthropometric data,19 20 measurements of pain pressure thresholds (PPT), peak pressure at the back of the head, time-to-pain and the self-assessed severity of the experienced pain (0=no pain, 10=worst pain possible)21. Average (±SD) results are presented separately for the entire tested population, male and female participants.

  • *The relative participant stature to stretcher dimensions is presented by dividing stature over stretcher canvas length (ie, 1.91m).

  • †The p values of the independent samples t-tests that were used to assess differences between genders.

  • ‡Statistically significant difference between genders (ie, P<0.05).
